or an NMotion 7" or 9"

i heard the ron woods are pretty good too

The ones said are the best IMO, Nmotin out of frame, Nmotion/JSR 9inch, Ron Woods Inframe pipe, Ron woods Pug. Careful on the pug, I know two guys that melted there rear resi with them.

Ive dynoed pretty much all the GOOD pipes on the yami and the dasa and the n motion out of frame make the most power. The dasa is what stayed on the bike we tested them on. It was a 60+whp nmotion480 yami. The dasa did everybit as good as the nmotion pipe but sounds ALOT better and is more rider friendly. DASA hands down. If not dasa then ron woods or the NEW Jsr pipe. Supposably they built a pipe that can compete with the dasa. His old system was good but 1.5whp down from the dasa. Ive yet to test that new one.

Some pipes with some combo of motor parts will work much better or worse then on another motor with different motor parts... but for the average motor build.... DASA, 9" Nmotion (used if you can find one), and possibly the newer JSR pipe.

I have looked at the pipe shootouts but they don't really say which would be better for racing up and sand hill. I know top end is important as the throttle is wide open the entire drag race. I would go towards the Ron Woods because it makes a lot of power on top but don't know how much it will effect the lower end.

my Ironman is a top end pipe but it also gave me a bit of bottom end. I do have the ScaryFast PowerNow in it just to let you know. It pulls and pulls and pulls now, right from idle all the way to the limeter. Pulled amazingly hard and hard to keep the front end down when i raced a KFX (beat him) up our drag hill at my dunes. Awesome pipe IMO.
