I have the ESR TRX5 pipe, and its hands down the best 250R pipe I've owned or tried (Paul Turner, LRD, FMF, or DG)

it has low end, mid and topend, I know it sounds too much to be true, but its not. I trail ride my dune ported 250R all the time with it, and the quad will almost idle around by itself, plus I drag race in the dunes all day long with it.

if you're not sure, go with the ESR TRX6, which is their MX style pipe, with even more low and mid (I can't imagine having more low than the trx5)

good luck

 

Hey dill did you have ESR do your porting?

 

nope, I had MP Racing do my porting. I highly recommend them, in fact, nothing I own will go elsewhere [img]i/expressions/face-icon-small-smile.gif[/img]
