This exhaust is top notch!

This exhaust is top notch! Quality is better then any exhaust I've had in the past and would highly recommend it! The sound on the xsr 700 is perfect! Loud but not obnoxious! I've had a bunch of different exhausts for the cp2 motor akra, M4, two bros and this sounds better then all of them by far! There aren't too many exhaust sound clips for this on the cp2 so I was taking a chance and I can say I am not disappointed in any way!!
