I'm looking for a moto-cross pipe.  Not a drag pipe.  Has Jerry made a 250 pipe yet?

to answer your question the paul turner is a motox pipe with no powerband like the fmf.

if what you want is a zingy hit on the top end.....you neeed a rev pipe. nothing motox about it.

more hp takes more revs or it needs to breath better in every way.

how much you want to change can take it from 35hp to 45 hp.

whats the question- im not a salesman.....

**Edit 1**

basically the paul turner and dynoport and shearer are the best. the dynoport is the most well rounded and not expensive but again no powerband zing... so  the shearer is the next best pipe but its expensive and the ftz makes it sound crumby in comparison. the ftz is no longer in production.

paul turner and dynoport are torque pipes with no zing. the shearer has some zing. nothing else available....
