Yoshi, HMF, Sparks, CT, Big Gun, FMF, MBRP

 

Sparks and then CT and the rest just play catchup!

 

Going to have to agree with you there.

The FMF and HMF pipes are great for trail riders though, excellent low and midrange power.

 

what about the yoshi? where on the powerband does it give its full effort? Is it very loud and is it worth the money?

 

Ct sonic is the best then sparks, hmf, yoshi, and fmf.

 

I would have gotten the CT but i noticed that it stuck out from the back of the quad about 6 inches. i do a lot of wheelies and flip it occationaly and i wanted a pipe that wasent going to get ripped off if if went back too far.
