Exhaust Help For A Friend!

[danniheyj82888]

My friend has a 06 yfz and wants to put an exhaust system on it. What pipes make the most power. I ride a 06 450r, and know a lot about exhaust systems for it, but Im not too sure about the YFZ. I told him, probably Rossier or HMF. I know Rossier is one of the top performers for the 450r. I have an HMF and love it, but I dont know how well it performs on the YFZ. Any suggestions? My friend was thinking about the NMotion, but I thought it was mainly a top-end dune pipe... and it is extremely loud.. I think my HMF is too loud.. and it makes that sound stock.

Rossier, NMotion, Sparks, Yosh are all great pipes. The NEW GYT-R is supposed to be within a couple HP of the Rossier and NMotion and quieter...

Big Gun is really powerful, and it looks really good. Lemme just say, out of the Big Gun's, i think the Evo Carbon looks so good. I love the carbon fiber pipes

I have a 06 YFZ SE and I have the Dr.D and I like it alot and 5 out 6 Pipe shootouts the Dr.D won.

the build itself will determine what pipe shines. i do have a HMF i will sell if you are interested.

SPARKS OR NMOTION. Nmotion is not a drag pipe at least not their 9inch pipe. Nmotion makes an out of frame drag pipe for drag racing.
