Has anyone installed all twins on the 9r yet? If so what’s your feedback
9r outlaw twins

Fixed it for you.
I see people stop in for advise on why they don't run right. Get upset when they realize they're a waste of money. Proceed to throw a tantrum about how awesome they are when they do work. Keep asking for fixes for all the issues. Get even more mad and leave.
They add weight and they are finicky about pipe temp. For the tiny bit of hp they can make when they're running good, they're a pain.
I'd like to see SLP concentrate on making a lightweight single pipe that adds power.

Kind of what I thought. They run pretty dam good stock, hate to screw that up for a bit a tiny gain. Thanks for the feedback!
Actually you drop 6 pounds over stock set up FYI. Yes they like heat.
There are guys who've got the SLP twins to run right, but it's not a simple bolt and go plus an ECU flash. Changing the port timing and relocating the EGT sensor are the key, I'm told. The downside is, I think it'd take a lot of tuning to avoid losses in on/off throttle situations. Somebody might be able to do it, but the pipe heat issue is huge in situations where you can't stay in it enough to keep them warm. So you stand a good chance of losing the thing people are raving about the 9R on - the responsiveness. For more open country riders, a twin-pipe 9R could be the ultimate sled.
900r needs a Terra Alps Racing billet head, muffler, ecm flash tune,then porting if you want the full power of it.
A good set of twin pipes will be good for more top end power.
There is no egt relocating needed, port timing is fine , but the 9r is expensive as mentioned. An 850 with head, ecm flash tune and muffler will outperform it.
If you have an 850, add a few good bolt ons and enjoy it.

Well there's the heat problem right there. They don't have enough thermal mass, and each only has the heat from a single cylinder so they're handicapped compared to a single to start.
It would be cool if someone made a 6lb lighter ceramic coated single pipe that had a real power gain.
Problem is the factory pipes are so good that there's so little left on the table nobody wants to spend the money. I'd be down for $500 to dump 6 lbs off the nose if it at least ran like stock with no other tuning necessary.
The twins with can drops 6# vs stock pipe with stock can.
Stock pipe with just about any can is lighter.
The “thermal mass” you’re talking about is actually greater in the twin pipes so it takes longer to heat them up.
It’s not 2003. It’s 2023.
Best thing for a 9R is throw the P-22 and the 2.75 in the trash can and replace with a P-85 and a Lynx track.

Hell IDK. Twin pipe thread correct? Then yes, correct thread. Twin pipes worked well pre-2003 era and achieving similar gains in 2023 can be found in the clutch and track for this sled.
If you could really gain 17hp with the twins, combined with the Lynx track and P-85, you’d really have a killer set up
If my Polaris had wings I would be the first to top every time as well...
