Steve williams with decades of experience confirmed from borla exhaust etc... as well as corso and magnaflow exhaust expert reps said the same thing about GM plastic 4 actuators which are located on the C7 Corvette mufflers have been melting! melting can cause a fire and at the very least causes the muffler system to be inoperative and the four flaps which open and close to allow air flow to either be stuck open or damaged because of the actuators located on the mufflers melting! mine although they might be inoperative as I hear sticking in the flaps opening and closing as engine accelerates which is a symptom of failure or potential failure! please order a nation wide recall to avoid someone's life being jeopardized and also engines being ruined because of these horrible design! call steve williams 805 986 8600 at borla a muffler guru and expert to advise you further. This plastic nonsense GM put as actuators has been a known problem for a very long time, especially affecting the C7 2013 and newer Corvettes! please help put a stop to this and order GM to fix these problems! see photos of actuators on vehicles which have melted. Please help! thanks!!! one of many complaints on Corvette forums! chassis this is an improper design by the GM team, putting a plastic cased electronic module directly on the exhaust pipe. Just bound to fail when the going gets hot. Actuators are expensive with a list price of almost $400 each, so it's well over $1000 to repair each time at the dealer for every one of my track outings. So far it's covered under warranty, but this can't really continue. If GM doesn't come up with a fix, I might have to sell the car. I bought it to go to the track and for now it fails every time I go.
