Dr D Exhaust?

[sdexrider]

Anybody have this exhaust on their 400? My buddy has it on his yfz450 and he love is but haven't seen it on any quads yet? Just wondering if it's worth the $$ or If I should just save up a little more for the Sparks X-6. I need a new pipe soon I have the E-Series but it keeps cracking Thanks !:grr:

DOnt know about the DR. D... I heard it is good for the YFZ, but never heard of anyone running it on an EX. The X-6 is proven, so you cant go wrong with that. Theyll have to pry my X-6 from my cold, dead fingers to get it away from me!!!

As far as I know Dr.D only makes pipes for yamahas. But maybe they are starting to get into the market for other manufacturers.

i have seen them for other bikes now. Dr. d doug dubach was one of the men behind the yzf400. he knows four strokes and i'd trust anything with his name on it
