I think I had a pretty good write up on this pipe last year when I got mine....but that would be on the other site. It'll pull...and then pull somemore....and then keep pullin....then again I have a Bartlett ported motor workin together with the pipe and the over rev and pipe workin together it well, pulls some more even. At first my PV wasn't adjusted properly and it made my bike seem pipey sorta like a Shee. But I adjusted the PV and it 'came on' sooner and was less pipey and alot more fun!! Never rode my 250 with this pipe and stock port work, but with this pipe, Bartlett porting, and a 39mm pwk I surprised/upset quite a few people on their thumpers. Except for that DS650 i think it was....and the Zillas I was with....my buddies with just a piped 450 lookin at my "little 20 year old ring ding dinger".....well.....a couple tried n tried but it wasn't happenin. I put a 20 yr old a$$ whoopin on them!

Its a great pipe!
