Went with a single system on a 08 crf 250r, easy fit, smooth and crisp power, nice tone love this system.
Great sounding exhaust and noticeable gains throughout the rpm range. Easy install. has taken allot of abuse and has not dented or broke at all. Packing has held up great also
Ive had a few rides on this exhaust so far and i love it. after being frustrated from constantly getting dents out of my titanium fmf factory 4.1, i decided to try the stainless steel pro circuit out. i don't notice any difference in weight and the power is so much better. its also a lot quieter that the fmf and was a million times easier to install. and of coarse, it looks great
I bought this exhaust for my 09 CRF450R. It's absolutely amazing how it totally changed the powerband. It took away a couple horses from the low end and added a few to the top end. Very smooth long powerband with a ton of top end. I don't like 450's with massive low end hit, so for me this pipe makes the CRF450R very easy to ride.
