I would look into the Trinity or Yoshimura pipes. Just my 2 cents.

 

Look up on LRD pipe

I have it on my bike and it rock. I used to have WB E-serie and not awhole lot of grunt compare to LRD. When I put LRD pipe it really woke up and come alive. It is alot better then WBE-serie.
Also other reason went to LRD due to nosie level at Oregon Dunes. WB E-serie ia alot louder even with the silcener core on it.


Give them a call.....

Is noise a concern for you? if so the Yosh is pretty quiet compared to some, and it has seemed to produce a noticeable gain in power for my raptor(01') a friend has told me though that some of the complete systems (he has heard) may take away from the bottom end a little. Also the Yosh is stainless, won't rust up like some. Good luck.

 

Yes...noise is a factor.we like to ride at the dunes.I hadnt heard about the full systems taking away,I DO know that on the 400 ex power was increased quite a bit. We have a Yoshi slip on 400ex,but the full system made a huge gain...

 

They had a pipe test for a raptor like last year, ct racing came in first for the highest HP gain... They sound cool to.
