I'm thinking of removing the front muffler/resonator (not the cat) from the exhaust of my R56 JCW
and replacing it with straight pipe to get a louder sound from the exhaust plus more crackle. Anyone got any comments, will this need a chip re-map, will it possibly cause error lights, will it make the exhaust sound noticebly louder or would it make it more buzzy/rattly? Does it have any noticable effect on acceleration/power? No problems with roadworthiness, S.Aust. is pretty slack- no annual roadworthiness checks- could almost get away without any mufler!
