This is my 35K mile g37s with a 6MT. Recently I installed my first exhaust component. The valvetronic universal muffler. Also included are the 3 inch carbon fiber tips. Not as loud as other axel backs mufflers with valves open, but louder doesn’t mean better. Noticeable exhaust burbles when shifting up and down. Excited to get a high fly cats and see how well the mufflers do at minimizing that sound so I don’t get in trouble with my HOA.
