hey guys,
so i have 2001 camaro SS it only has a lid and an SLP cat back (loudmouth 2) and when im not in gear(m6) if i rev over about 4000 rpm she will make a crackle noise when im leting off the gas. sounds to me like a back fire but im new to LS1 .. does anybody else have this problem with LM2? is this even a problem?
thanks in advance you guys are always great help!
