I refently replaced my Dynomax SuperTurbo muffler with an Flowtech Terminator and it gives out a great tone. Very different and not your every day run of the mill sound, its great. Gives a nive grumbling growl when you step on it too. Using some Dynomax I pipe 2.5, and same diameter tailpipes. I will change the setuo in time 20 3 inch I pipe but for what I have planned for now it will suffice just fine. So if anyone wants something a little more unique I higly recommend the Flowtech. Also noticed the muffler does breath beter as well which is always goos for the L03 engine.
