I agree except for the MBRP, in most cases it fits where you put it, but the MBRP can for the PRO is the trail version and has a 6" body instead of 5" like previous Polaris models, thus I would say if is about the same decibels as the HPS etc.

I wish someone had a video of a pro with a Dynoport Big Core Barker, I heard one on a Ski-Doo 1000 once that sounded absolutely awesome on-off throttle, and was just a touch loud full throttle, Just didn't want to be in front of hit when he pulled a wheelie out of a ditch.

 

[PalousePoo]

My BMP powder light is hella loud and super light. It also causes a slight bog sometimes around 6500 rpm! Only other cans I've had is a HPS on dragons. Nice sound and not as load. Gonna go with one of those on my 13. BMP has held up well for 2000 mi though.

 

[druchti]

HPS is 7 pounds lighter than stock.. Holz racing sells them on there site and aslo claim a 3.75 Hp increase. first I've heard of a Hp increase.. can anyone verify this?? http://www.holzracingproducts.com/s...-pro-rmk/hps-lightweight-silencer-pro-rmk-800

where does the GGB fit in the lineup ?

Power addiction also sells them. They don't claim a horsepower number, but claim a 100 rpm increase, which means a slight horsepower increase.

Agree I run an MBRP and it's not loud at all. My take:

noise

They don't shut you down for noise..If your riding inn a park or a community where people live then I will agree. However when you ride inn the high rockies at 11,000 feet where no community lives then noise is not a factor. What shuts us all down is when riders damage property, vegetation,fences,litter, etc..... A loud can ONLY effects riding inn a area where the decibel rating is set in place.. Loud can does not affect in the areas of riding that is away from the trails and parks. When you travel thru a area of this nature parks,trails,sightseeing,communities etc.... then yes be respectful to the area your inn and do not stab the throttle. Treat it like the wake less area of a lake. Boaters have what is called captains choice on their boats. You can it noisy boat or quiet quiet boat be responsible enough to know when too use it. A noisy can inn a area of no man land is like saying you can't shoot a 300 ultra mag rifle during the hunt your better to shoot a 22LR due to the muzzle blast noise. Wildlife are not at 11,000 feet inn 10-12' of snow if YOU!! do come across some wildlife then yes again be respectful enuff to try not to scare or chase them. Animals are as scared from a stock sled just as much if you harass them or chase them again do your part to respect ther habitat they live inn. If you get harassed in the higher elevation then your riding inn area(s) that is closed then they will add to it for noise. Be aware of where your at and when and time too use it.. A great sounding sled does not make your parks or riding areas shut down!!! It bad choices on our part that shuts areas down.

Agreed, Have never seen an area closed due to noise. In my area closed off because of supposed impact to certain species of animals.

 

[Nooby]

My 09 RMK with BMP powder lite is throaty and a bit noisy at WOT. My 16 pro with the same powder lite is F-ing LOUD !!!!
The old one weighs in at 5.9 and the new one weighs 5.8 fwiw.

 

[goridedoo]

You guys are dead wrong if you dont think loud sleds get riding areas closed.


BMP powderlite and GGB mountain cans are both ridiculous loud, I would highly recommend choosing a quieter option.

You would have to give me an example. If loud got things closed then harleys couldnt ride anywhere. They are everywhere and LOUD and around everyone to hear. Modded chain saws are everywhere in North Idaho in the woods and can be heard 2-3 miles away but no restrictions on those in their 50 year history.

From previous posts in the following thread
http://www.snowest.com/forum/showthread.php?t=169992

OK... I'll start up a nice "HOT" topic that, IMO, needs to be discussed more... especially as we see more and more lands getting closed to sled access.

Non-Snomobiler impressions of snowmobiles are being directed by some people that primarily show loud exhausts in videos etc to ruin the public image, of snowmbile riders and their machines. Non sledders/offroaders outnumber sledders/offroaders by a Gargantuan margin.

"They'll have to pry it out of my cold dead hands" ??? Well, "they" just might

And "they" wont just be granola crunchin greenies... I've met plenty of card carrying, large carbon footprint, ultra conservatives that could give a rats azz about sledding and find them to be very irritating... so lets not make this into a Conservative Vs. Liberal thing.

Loud exhaust does not equal "PERFORMANCE"... It just makes you feel that your sled is making more power... compared to a Well Designed quiet exhaust. You can design a quite exhaust, be it 2 or 4 stroke, to make just as much power or more than a straight exhaust...It just costs a bit more.

"Screw the Greenies... I'll run as loud of exhaust as I want to!!" is actually "Screwing" ourselves as snomobilers....

I like the sound of a nice loud engine running in good tune...Weather that is John Forces funny car or a good running MX bike.

But we live in a shrinking world today

What sounds "Sweet" to you can sound really BAD to others.

Look at it this way... if you were sitting in your living room, with your best buddies, watching the Superbowl on your new surround sound equipped 50" plasma TV... beer is flowing / steaks on the grille...... and in the middle of the second quarter....the neighbor kid and 6 of his buddies decide to "tune" their chainsaw-engine powered Go-Peds for the next 2 hours, on and off ...with straight pipes..... Would you sit down and say... "Heck, junior has the right to run what he has....I'll just turn the volume up a bit"

OR

You are fishing a great little trout spot... and 6 loud dirt bikes decide to ride there while you fish...

OR....

You are hunting and somebody keeps ripping buy in their modded turbo RZR for a while and scares off that prize 12 pointer....What would happen?

Others may say "Well that analogy doesn't apply to me....I only ride EXTREME backcountry and there are no other people around"... Is that ACTUALLY true??? Do you live and ride in the Yukon hinterlands?? Can no one else hear you... when you unload in the lot, or take the fire/logging road to get to your favorite spot??? If you really can say yes to this... then you are in the 0.05% of the snombilers out there.

"Loud pipes save lives"... That dog just don't hunt anymore... that excuse has far too many negative consequences to it.

IMO, Loud cans/stingers or straight Turbo exhausts are bad for the public image of sleds...
Those that ride with loud pipes are causing more damage than just "pizzing off a hippie". They are taking away from the future of snowmobiling in the backcountry....

Radar guns, speed limits on trails with Police watching....boy, that sounds good!

Bad public image of snowmobiles...even from people that are NOT 'greenies' starts a chain reaction from other people that don't care if motorized access is closed.

It is sad to say... but the PUBLIC OPINION will decide weather or not we have sledding access in the future.

We don't need any new people that want to take away sledding access.

Manufacturers that make loud exhaust products are actually hurting, IMO, their own long-term ability to make a living off of snowmobiles...if sledding areas keep getting closed at the rate they are = big problem.

FLAME AWAY!!​

Why is it ok for Harley riders to have bikes that are so darn loud they can be heard from MILES away, when 1/2 way across my town on the hwy?

I see your point and respect it.

I live in a big Harley town.... people get pretty big tix left and right for loud pipes here on their scoots... as they should IMO.

BUT....Harleys dont have endangered riding grounds like sledders do... and there are a whole lot more of them than sledders....

Lets keep this on track about snomobile exhaust and not "It just not fair"...

It is NOT the extreme environmentalists that will close down the lands to motorized access....It is the PUBLIC at large that will...Thier opinion is based on things they can see and hear....



The quietest Stock sled made would Still scare off a deer or other animal.... this is not even really a point is it 583?


Actually it is... Don't take something as easy as this to 'fix' and refuse to do it.



Not going to happen....the sleds should be quiet to start with....just like the Harleys with straight pipes....

Citys have noise ordinances so that YOU are not bothered by every motorhead that would run open pipes on their bike/car/truck...
There really are not that many noise ordinances for the sleding world, YET, compared to the large amounts of riding areas out there... sure we have yellowstone and the new Colorado dbA rulings... but this is a drop in the bucket.


It boils down to this.... People who dont have feelings one way or another about sledders WILL become opposed to them if the exhaust noise remains high...

Fact is also....There are MANY MORE sleds out there than there used to be, heck look at the population of this site alone.... There are more people that think it is cool to have a loud exhaust on their sleds.... same as the 1950's on the streets with hotrods.

How many straight dump exhausts do you see driving around your town without getting tickets. Probably very close to NONE.



Noise MAY have something to do with it... maybe the skinny skiers in this group got buzzed by a close flyby of some obnoxious Apex with straight dump turbo or a twin piped 1000 with race stingers (they call them stingers for a reason). Maybe that happend just the past weekend... Maybe a snowmobiler , as one member of this forum put in a past post, went "clickity click over thier planks with thier cutter carbides, f***ing treehuggers, they make me sick"... maybe that is why they scowled at you. Maybe you image of "skinny skiers" is why you probably scowled right back.

By not acting like responsible people....just like the loud Harley guys.... WE, as Snowmobilers are becoming our own worst enemies.... much more so than any environmental group because we are making the ammo that is being shot back at us and the public at large that Does have the power to shut down sledding and other motorized public land access.

AGAIN... it is the PUBLIC OPINION that matters here.... Those people are NOT GREENIES or Motorheads... just people that vote and pick representatives that decide what is going on.

I hear "I'm not going to give them the satisfaction" OR " They wont tell me what to do".... Well, the public is NOT asking for your permission.... That is just the way it is.

Police ourselves or someone will do it for us!!

True True...

But we are not talking about ONLY greenies here.

Lets make that clear.

Loud exhausts can turn someone, that is not opposed to sleds, into a 'greenie' on the topic of snowmobiles real quick though. Most aftermarket exhausts are borderline obnoxious (or full blown)... the less expensive ones especially....even more so as the packing burns out and it is not replace. There are more cheap exhaust sold OR turbo systems without mufflers than quiet units.

If your extra 3.8 hp comes at the cost of me loosing my priveledge of snomobiling in the backcountry... the choice is easy for me.... and it should be for you too.

Race pipes don't belong on the mountain, IMO.... unless you can make them sound reasonable.

And.... Snowbilers are still looked at like the Koresh Branch Davidians of the backcountry world by the public at large.... those things that stand out like littering, loud exhausts, sleds that are out of tune and belching smoke, destruction of property... all these little things that can be fixed easily are going to give us the same fate a the Waco group if WE dont fix them.

There are more sleds on the mountian than ever before...

More interaction with the public, on our sleds, than ever before...
More snowmobile triggered avalanches in the News....
More encounters with snow shoe'rs, skiers, SAR crews, trail maint crews, forestry service, people at the gas station...

In general, more people actually see snowmobiles than they have in the past.

If this "interaction" is less invasive to others around us, as we enjoy our sleds... the better chance we will have to access the lands we enjoy riding in the years to come.

Our loud exhausts won't be taken away... The sledding lands we enjoy will be.

I want to be sledding for many years to come... I want to see lands remain open to backcountry snowmobiling, parts and sleds to be made and the happiness of my fellow sledders shared!!

The fact is, we will continue to lose land usage rights... that is not an "If" but a "when"... I want to see as much remaining as possible.

[mountainhorse]

X2M3.... I know what you are feeling.... Remember, we are all sledders on this forum and we all care weather or not we'll be able to sled in the future.



The groups that want to close off access to the trails are NOT asking for you to "GIVE" them anything... If we as sledders don't choose to interact with the public in a civil way... closure groups will continue to use our own lack of control against us.

"Why give them and inch, they'll take a mile" Also works from the oppositions view, for the same stubborn reasons that sledders with loud pipes/Turbos use.

Now about outboards....

I'm in the marine industry (Yachts), and in the antique boat preservation business for some time now.

Underwater exhausts have been around since the 50's....at the request of the Users/Buyers of the engines so that they were enjoyable to use. Run a 250 hp Optimax outboard and tell me that the engine lacks power.

I've used small lakes in Michigan and all over this country since the the early 70's (before that when I was a kid).... Going to cleaner burning engines and taking away the ability for people to mix too much oil has been a benifit to all those that use the lakes... The oil residue on some of those lakes back in the day was pretty bad. That is the reason for going to injection and getting away from premix. I have ZERO problem with that as a user of the lakes, a mechanic and user of the lakes in general. If it adds to the complexity and cost.... so be it...gotta pay to play. 4 strokes on the lakes are the best solution... I see plenty of bass boats that can do 60mph + with a 4 stroke on the back.

I could go on Ad nauseum... but what does this do for SNOWMOBILING?

I see the rest of the sarcasm to try to prove a point... but really, does it?

ICR, the builder of your exhaust chose to use the least expensive mufflers available for your install, I can see the many reasons for it... from keeping the customers business by not making the price too high, to keeping the profit margin so he can pay his heating bill... But like you said in your earlier post, you would pay more if something was available. Did you ask him to make it somewhat quiet when you had the pipes made?

You also, I noticed, live in Fairbanks... lots more friendly "others" and much less dense in population than say Colorado, Utah, Wa or Ca...
A snowmobiler in Colorado has different levels of exposure to the public at large. In short, you run into less people that don't like sleds than your average sledder on mount hood or Togwotee.

Is your need for the last drop of power more important than others need for an enjoyable outdoor experience... including other sledders? Is it more important than keeping lands open for as long as possible?

Don't get me wrong, I consider you as a brother in the sport, and I mean that sincerely, that is why I'm taking the time to present this topic... If you and I sat down in your garage with a beer, we'd probably end up talking for hours about how we love snowmobiling and wrenching... so please don't take this discussion as disrespect for you.

You want to make your stand on exhaust... Normally, I'd say go right ahead, but your decision to do this gives the opposition more PUBLIC justification to close down access for everyone.

I am a firm believer that if WE, as snomobilers act on our OWN behalf to participate more responsibly with the public we share the mountains with, we have a better chance of enjoying the mountains in years to come... Right now, the writing is on the wall, and it does not look very good for access for OHV's.

When the closure groups show videos of sledders to prove their point, they dont show Mom and Dad on their clean burning XP or Nitro with little Sally sue on the back in her pink helmet.... they show the guy on the turbo sled with straight dump exhaust using trees for traction Brappin loud enough to be heard in the whole valley.

When it comes to legislation for land closures.... ESPECIALLY in this economy... if it comes down to the cost of sound sampling out in the field or closing down the area and not having to pay for this.... well then, often times these days... that is an easy question to answer.

I feel for you and the point that you don't want anyone to tell you what to do... but at some point, we need to step back and take a look at how much we enjoy what we do here and regulate ourselves.

I'm a mod sled owner... Love the wrenching, the performance and hanging out and just talking about it sometimes...BUT, most of the mountain sleds out there are run BOX-STOCK for their entire life.... way more than are modded, even with just a can.

Like I said before, your loud exhaust will not be taken away, your abiliy to sled in the backcountry will.

The New Colorado sound check system is in place because the sleds were too loud, there is not a stock exhaust, in functioning condition, made in the last 10 years that wont pass this test, I doubt that there are any of the SLP systems or other companies that make it a point to invest in technology to make exhaust that performs well, and controls sound output. Companies, like SLP, have helped stave off a govt mandated ban on aftermarket exhausts being manufactured.. that will be the easy way to limit it. They do it with aftermarket car parts, it would be much easier to do it with sled parts.

[Yaeger34]

the pro I bought came with a SPI exhaust (not slp). Hoping its not too loud and annoying. Can't find much info on a search. Any input? (loud sleds give me headaches).
