46SF Muffler
Kallikrates, Do yourself a favor and buy a MVVS .40 exhaust system. I have Knife and Spinsaion with an OS46SF and the MVVS exhaust and this combonation is unbeatable!!! You will have to file (elongate) the holes in the header but it is only a small amount on each side.
With this combo you have instantaneous throttle response. :thumbup:
