Ever since I put on a custom flowmaster muffler I get a loud backfire type bang out of the exhaust when my 2017 Cruze "L" auto starts (for example when light turns red to green adn engine auto starts). I have learned how to bypass the system by putting shifter into "L" then plus button (+) up to 6 which is highest gear on my model. But am looking into purchasing an electronic start/stop Eliminator. Anyone out there ever find one, purchase and use it? Thanks.
