Don’t let the price fool you, FMF didn’t take any shortcuts with this pipe. This is a full race exhaust featuring a titanium canister and formed rear endcap as well as FMF’s exclusive Factory Forward Engineering – lowering the center of gravity and centralizing mass but that’s not all. The titanium PowerCore utilizes advanced multistage packing material and a Hi-Flo stainless steel formed front endcap and midpipe - all for less than what you expect to pay for an aluminum muffler. The titanium PowerCore performs better than stock, is lighter than stock and has a sound output of only 100dB.
