Light, powerful, trick
I have ran this system on my race bike for the past 2 years. As a fast Vet intermediate level rider I need power everywhere and this system delivers. Where the stock system falls off in the upper rpm's these bad boys keep producing power. Not only is there no sight of sign off with this pipe and header, it is light! I mean really light!

A little loud, but nice sound
I have had this exhaust for many years after running both the stock exhaust and an XR's Only exhaust which was super loud. This one has better mid range to top end than both the other two exhausts mentioned. It pulls to the moon, just like my 2 stroke pro circuit exhaust. Finish is nice.

Strong running Pipe
Pro Circuit makes a very high quality pipe. Fitment was excellent on my 2008 CRF250R except for the fact that the can presses out on the number plate (which is the only reason I gave it 4 stars for fitment). I also didn't like how far the muffler stuck out past the # plate (I liked that the duals didn't stick out at all) but that's just cosmetic. Now the performance... Seems like it added power everywhere in the rpm range and really punched up the throttle response! Can't wait to see what it's like with a Hi-comp piston!
