I've been looking around the web for aftermarkets exaust and not finding much for the EFI's. And if I switch, would I have to do a tuner? I see that there are several out there for the 500 HO carb and the 700-800 sp but not 500 EFI. I'm pretty happy with the power but would like a little more aggressive sound and any hp bump would just be a bonus.

 

Looking for the same thing. Suggestions would be nice.

 

Aaen

 

Aaen makes a great pipe and you don't have to re-map. They are a bit on the loud side so if that isn't your thing then try HMF.

 

May you just can add a aftermarket pipe and the EFI will adjust itself like they can with elevation changes?
Or do these aftermarket pipes advertise "Not for efi" of for carb models only?

There the exact same motor just one has a 39mm throttle body and the other has a 40mm carb.

 

Aaen is showing one for my model but many of the sites are showing pipe for the 05-06 but hardly anything for the 07. Makes me wonder why? But does'nt matter now, till I figure out this over charging problem which could cost me $300-$500 to make it right. I'm hoping it's somthing petty but seems like lately s#!t is running down hill at me every time I turn around. Every time things are looking to good to true, Somthing always happens.

 

HOTSEAT performance makes one for our 07's. They're $265. Look up speedwerx.com, they make alot of after market stuff for arctic cat(speedwerx) and polaris(Hotseat perf). I've heard the HSP can sounds real nice and not too loud unless you go deep and get the baffling inside wet. There's a couple sound clips on you tube, when I get some extra coin I'm gonna get 1 of these. The Aaen cans are pretty loud so I've read from guagedholes, I like a nice tone but not so that my brains rattling between my ears. The only thing that sounds good that loud are late model race cars or cup cars or better yet offroad trucks like Robbie Gordans !
