Does anyone use this pipe on their raptor? Ive heard that this pipe is really good for other quads, but need to hear a lil more reviews with it on the raptor. The slip on R4 is only about 200 bucks so definetely priced right. I've heard that a lot of white bros pipes dont require jetting, and in fact, say leave the jetting stock. Is this true with this pipe? Any help is greatly appreciated.

 

i have only seen a raptor with that pipe go up a hill in the dunes it looks like it does a does a good job but im not sure there might be something better

 

I have one you can see on my pics near the bottom..I think it's o.k but am taking it off to put on either a CT Racing pipe or a full Yoshimura system.
If you like the White Bros pipes... The E series puts out more power than the R-4 and yes I had to jet it I went to a 140 145 and even works good at a 145 150 with no air box lid and a pro flow intake

 

Ive got an E-Series and my friend has an R-4, they are both good pipes but I like the looks of the E best. I dont know which one performs better since Im more modded than my friend's raptor and we never raced just piped and jetted. I rejetted when I put on the pipe since I got a k&n filter at the same time so you might/might not have to rejet, every quad is different.

 

go for the full Yoshimura system that is nice
