The forward bracket on my Big Gun Race exhaust finally broke completely off. Interesting rattling sound while riding. I installed a spare FMF Q pipe i had in the garage. A few things I noticed: less overall power, but smooth powerband. Harder to start(?) Nice engine braking. Just takes a while to get used to the new exhaust note. Can't tell what gear I am in and when I should shift. Other than a noticable decrease in overall power, it is really a nice pipe. And who really needs the power of a wide open 450?
