i have a 1988 xr250 and i was wondering if anyone knew of a good pipe that would increase the bottom a little increase the middle a lot and add a little to the top. I basically want to give it more power everywhere but more to the mid. I was currently looking a xrsonly, white brothers e-series, or the fmf mega max. Also is the xrsonly complete system (pipe and headers) any good?
Thank you:p
