This weekend I finally went with a buddy who is running a sprintex supercharger to get the last piece of exhaust installed; "resonated front pipe" which cause his exhaust to sound as raspy as a honda fart can. He is pro tuned with ECUTEK and running catless UEL tomei header, tomei over pipe, resonated invidia front pipe and resonated & muffler invidia N1 cat back. Two resonators but still raspy AF. Does anyone know if this will eventually go away, wil a revision tune get rid of this raspy sound? I've searched all I could and cant find a solution, any help is appreciatted.
