Re: Fat Cat Expansion Pipe
I have ran a few of these with excellent results and the difference between this and the stock pipe is substantial. As for noise, well I control that with my right hand. It is easy to come off the throttle and quiet things down as I motor by people. I do improve them by cutting off the stock flange and using my own ported flange. I also tuck it up and back towards the bottom bracket when I do the flange swap.
