2011 covert exh. butterfly thingys..
i found out only on the convert gm decided to add this pos.. i went under there and loosed the tension to the damper to wide open all the time.. and man its sounds great.. before at low rmp take off you got that stuffed tailpipe sound that sounded crappy... i guess will be my temp fix to an actual axle back system.. has anyone else done this.???
future mods cai, axle back and custom tune... thanks
