I don't know much about speedwerx but I know that jaws builds a good pipe. But you are going to pay for them and I think Jaws buils pipes for modified engines and they don't always fit the best (hood/belly pan problems). Aaen's are a good bet. His pipes seems to fit in the chassis nice and have a nice sound. We have a set of his trail pipes on our 670 and they work great. Aaen is a very smart guy and easy to talk to. I would ask him what he has for stock motors.
Chubby, How much gain did you notice with the D-port pipe? More than just noise? Or did it really make a difference? Also, does anyone know if Crankshop makes a single pipe for the 800 twin? and how does it work?
i'v have had the dyno port pipe it worked ok but the crankshop pipes i have on them now works great they have alot of mid to top end and i did not loss any bottom end the dyno port pipe made 91 foot lbs of tork and the crankshop made 95 lbs of tork but you have to have them set up wright if not they will not work plus i do have a dyno port pipe for sale
