I have a healthy 451 and am using a stainless magnaflow 2 1/2" system and it's pretty loud, especially when I get on it. I'm thinking of using something at the end of the tail pipe to act as a resonator? It's not too loud in the car but behind somewhat.... not REAL loud but enough to attract attention. I figure sooner or later the police will be on my case.....
