With all this talk about loud pipes ...

[Dogmeat]

The other thread got me thinking ... I'm not advocating super loud pipes, but with that said, I have an aftermerket exhaust on my quad, and an aftermarket can on my RMK...

The exhause for my quad has a "US forrestry service approved" spark arrestor, and right on the muffler it says it meets "96 dB sound requirements" and says that it will not exceed that number...

This got me thinking, is there a standard such as this for snowmobile cans?

The SLP can I have I didn't think was obnoxiously loud, but are there actual metrics for snowmobile exhausts the same way there are dirt bikes and quads and stuff?

If not, it might be a good thing, because this way aftermarket manufacturers could legally claim that their silencers are not too loud, etc .... might do us all some good?

I dont know what do you all think?

I believe there is.
The forest service has been saying for a couple years that they are going to be doing sound test the same way they do with ATV's.

My SLP can that came with the KK when I bought it wasn't much louder then stock but the sno stuff rumble pack I put on it now braaap's pretty loud. I love the tone of it, and I'm out in the mountains so there isn't really anyone to bug. Most riders I meet have similarly loud exhausts for the most part except for the 4 strokers. They are pretty quiet.

Several years ago alot of the aftermarket companies signed an agreement to not design or sell "loud" exhausts except for racing. We all know that gets abused, but SLP has been the leader in quiet performance. Their silencers weight a little more but are generally quieter than most others.
ALot of states are implementing sound regulations but the testing procedure is a sticking point......do you test on the snow or on asphault? RPM? MPH? What side of the sled?

 

[powdersledder]

In many states and national parks it is illigal to modify the exhaust. That means no cans and no pipes

It's weird, but after riding my Nytro for 1,700 miles with the stock quiet exhaust I would never own a loud sled again. I put a loud pipe on it and sold it after one ride. It's nice having a quiet sled, especially if you load really early or late at night.

Why not just get some walkie talkies instead? They are much more useful too.

SLP is the only way to go for a lighter than, but quiet as stock can nowadays. Dumbazzes that like loud should just port your helmet or ride without it. Riding responsibly and knowing where your buddies are at all times is what saves lives, that is a lame azz excuse and is old.
It is alot better to be able to hear the rest of your drive system and engine instead of an abnoxious can. Have fun changing your hearing aid in a few years.

Maybe.........
if they happen to break loose an avy when you are a mile away!
(except pity the poor rascal on the hill at the time!)

I know what you all are going to say " You are a flatlander "
But.................here in NYS you cannot LEGALLY modify your exhaust.
Not to say some don't but even an slp system is not supposed to be on the sled and you can be fined for it.
Sucks to be me

I have a slp complete exhaust, its not really loud but as for listening to the engine and drive system, I ride with guys that have rumble packs, they can hear the slitest things, you just get used to it

I thought noise could not trigger avy's.

I used to think the same thing about not being able to hear anything over a louder exhaust... well, I got a Rumble pack, and I can hear every little detail sound from the engine, track, chaincase, you name it... not hard at all when you know what to listen for.

 

[powdersledder]

I hate race cans on the trails because they are so retarded. Nobody cares if your little 500 sounds just like johnny snocrosser's sled. But I love pipes, I can tell exactly what is happening with my sled just by listening to the exhaust. not to mention the extra kick they give

 

[MARCUSO]

This is true!

I thought noise could not trigger avy's.

HUH??? WHAT??? WHAT???

Noise is not supposed to trigger avalanches. I was told from a reliable source that U.S. armed forces tried to trigger an avy with a jet fighter's sonic boom, and were unsuccessful.

People think that because you are in the backcountry, you do not affect anyone with your noise.... What about wildlife? You know, if some people would not be so selfish, I think that the backcountry would be a place welcomed by everyone.

I, Myself have a stealth thing can on my REV, and it is not too loud, but it has a nice exhaust note.

 

[KingCatz]

Wildlife? There's wildlife back there? I never see any! lol... Eh, personally I would rather have the deer and moose, etc, far away. There is plenty of room out there.

I guess I think it might be a beneficial thing if snowmobiles were held to the same sound standards ATV's are ... I think the 96dB standard appears to be a good compromise, at least judging from the exhaust I just put on my quad. It's loud enough, but not too loud. It's sure one hell of a lot quieter than a similar quad with the baffle removed at least.

I'm sure the guys running full-on modded out sleds with twin pipes would be very upset were something like this to come to pass, but I think it's pretty safe to say those guys make up the small minority of snowmobilers as a whole, and if this was something that would help us fight land closures, then I'd be all for it.

I just read what I wrote and it kinda makes me shake my head because I really hate the idea of having to make concesssions, but I mean you gotta admit that if you have a group of 5 or 6 guys and their sleds are all wrapped out at like 110 dB it's kinda loud ... heh

I dunno. I guess the bottom line is that if something like this actually gave us a benefit in not having riding areas closed then it would be a good idea ... whether or not that would be the result, who knows ....

Perfect ammo for the greenies. way to go dork.

It's called disrupting habitat. It's like building a subway right next to your house. It used to be quiet and all, now there is a big noise every once in a while.
Guys like you probably litter the backcountry too.

my exhaust exits about 6 inches after my turbo so my sled is pretty loud but a nice tonefell sorry for the guy in nys who cant do anything legally to his sleds exhaust
