Has any one used one of these? Any suggestions on aftermarket exhaust?

Heard one on an XR250 that a USFS Ranger was patrolling on. Was impressively quiet but I don't know about the performance? I'm waiting
to hear some feedback cause I would consider shelling out for one if it ran like my uncorked stock pipe. Thta's not asking for too much..is it? Posted Image

I have one on my ’01 YZ. It does not run like a stock corked WR pipe, I do think it robbed a little low end over a stock YZ but it may rev out even quicker.

It is quieter than a stock YZ, but a little louder than a stock 520 EXC for example (and as large as a stock EXC silencer). But my bike does sound very much like that bike would if it revved to 11k.

Much, much, much quieter than my old PC T4, that is for certain.

If you want a lighter pipe for your WR that will gain power but isn’t excessively loud or expensive your best bet is a used YZ can IMO. Beyond that I don’t think there is really that much difference among the zillion aftermarket pipes you can get. White Brother’s and FMF products are tried and true, although that new Dubach pipe is supposed to work well. The Arrow system that is starting to be imported is supposedly quieter than all these but it is even MORE expensive, if you can believe that, and doesn’t have an S/A that I am aware of.

Hope this helps.
