This lightweight silencer reduces weight by 3.25 pounds (4 pounds on the 2013 models). Its slim design and ceramic coating reduces underhood heat and gives more clearance from the side panel. It also has a more positive silencer to belly pan seal to ensure exhaust gases cannot re-enter the underhood area. This product is SLP tested and passed SAE J-2567 stationary sound tests below 88 decibels. It retails at $299.95.
