Ok give me your vote on GYT-R, White Brothers R4 , or White Brothers E-Series and finally the hmf system since it is cheap going with the one with the most votes.

 

"e" series

 

GYT-R they tested them on ATVtesting.com and the GYT-R performed the best.

 

That was with the head pipe. We're talking just Slip-On!

 

Of your choices. "E" series.

I would also look into the Yoshimura slip on. Graydon, CT sonic also have slip ons I believe.

 

I have the e-series, it melted the little refector on the grab bar[img]i/expressions/face-icon-small-mad.gif[/img] So if I were to do it again it would be the Yosh.

 

From those listed.......HMF

 

GYT-R Carbon fiber slip-on. Were talking slip-on not head pipe! Guard dog. They never tested full pipes in atvtesting.com just slip-ons.

 

I have the E-series and love it - I've had it for 15 months with absolutely no problems. I also have a deflector disc on it to deflect the exhaust away from the grab bar. I have JUST purchased a W.B. headpipe to go with it!! The E-series canister with the K&N and proper jetting woke up my Raptor quite a bit. But after 15 months I am looking for just a little more so I am going with the headpipe now as well. I will also be port matching my carb boots to the head for better flow.

 

Gotta go with the E-Series. Works great for me!;
