yea this kid is talkin with his head up his ***. plus hes talkin about a Raptor 350.

 

Yes the quiet core will drop your power a little.Think about it its common sense the reason you buy the hmf is to unplug it let it flow freely and the when you go pluging it back up of course its going to hinder the power a little i dont think it will alot but im sure you will feel a diffrence.

 

hey where are some good sites for raptor 350 performance parts

 

Sweetquads.com, he has good deals on HMF and pro design, Rockymountainatv.com for whatever else you could need. Tom at sweetquads is the man, great guy to deal with.

 

thanks hey do you think a uni slip on muffler is worth a try from like fmf or white bros

 

I "obvisouly" dont know what im talking about but i will welcome you to the forums!!!

 

ok

 

On the raptor 350 the stock headpipe is so good that you really can't make power by replacing it so i suggest only getting a slip-on. I like HMF, for the money its hard to beat. A good slipon and a filter will wake up your bike, but you have to rejet. The sell those powerup kits that have a filter and jets all in one package, but the stock replacement k&n that comes with it blows, and you'll end up throwing it away. If i was you id go for a jet kit or just have a shop jet it, a slip on and a pro flo intake.

 

is it hard to jet

 

not at all, expecially on the 350 its easy.
