Gibson Performance Exhaust used my 2011 Dodge Challenger SE to protype a new exhaust line for the new 3.6L motor.. I am extremely happy with it, it sounds amazing, as well as it gave the car 13rwhp.... The exhaust makes the car sound like an f-1 style race car and the exhaust actually has a detonating sound inside the exhaust when the transmission switches gears..... hit me up if you want to know more... this has got to be the best sounding v-6 on the market.... Thanks Dodge & Gibson
