Well in my opinion you should go with the Yoshi, you can get a full system for around $400, also I would recommend getting the pro flo kit with K&N, you can just run a regular K&N, and cut some wholes in your lid if you want also. As for jetting a dynojet kit works really well on the raptor, it changes the springs that are in the carb, also, and bump your pilot jets up one size from stock. That should be pretty close with a lot of the top exhausts!

 

what kind of riding do you do?
are there noise restrictions?
How much do you want to spend?

theres a lot of brands out there. personally ive had yoshi very good low/mid and teh sound is low. and now i have the fatboy 4 and it has more mid/top and it is very loud, the fatboy has jets included.

 

i also like the yoshi...but there r alot of good exhaust. i have the full yosh comp, pro flow with K&N, no air box lid with outerwear cover, dynojet 146/148 with stock pilot.

 

i dont own a raptor so i dont really know which exhausts are good but from everything i heard alot of people like Yoshi as for air filter i'd get the k&n with pro flow adapter and outerwear and remove your airbox lid i got one on my banshee and its great

 

Get a Sparks for the pipe and a UNI for the filter, but I dunno about the jetting.
