I run a full Curtis Sparks X6 on my fully built 426 and love it. Much larger than stock, allowing the engine better exhaust flow. If youre looking for a monster low end pipe, I would go with something else though, since the larger diameter reduces the back pressure and doesnt do much for the bottom end. If you ride hard with the bike midrange to upper RPM, its one of the best pipes out there...

I run a full HMF (ceramic coated inside and out) courtesy of C&D Racing.

Couldn't be happier...

Your gonna get ALOT of variations on that on whats best and price differences too. HMF,Yoshi,sparks seem to be the popular pipes that riders like the most. I run a Yoshi full system in mine .
