Caps a three-piece exhaust system that features a titanium (or stainless steel) header system, a titanium (or stainless steel) mid-pipe and the Titanium 4 muffler itself
Standard 14 unit offers the greatest power gains at the expense of a louder sound level not the best choice for sound-sensitive places
Ti 4 muffler requires an FMF mid-pipe to fit properly (the header pipe is NOT required, but highly recommended over the stock unit)
