Borla exhaust problem
I bought a 2014 Z51 stick shift C7 when it had 4800 miles. It had a Borla exhaust installed. Recently one of the exhaust actuators failed; it striped the gear set and began to make a loud banging noise when in the Eco mode. The dealer replaced the actuator, but the computer fails to 'learn' the new one. They have called GM, Borla all kinds of things for over 4 weeks now and still can't get the check engine light to go off. The new actuator works fine; no more noise. They now tell me the only way to fix this is to reinstall a new OEM exhaust ($2600). I thinks it's a computer setting problem, has anyone else experienced this?
