Is almost time to replace the muffler on my 560SL, some one took the cat out already, i was thinking maybe putting or custom meke make a complete dual exhaust for it, has any one tryed this? is there enough room under the car for it? Do i need to make a crossover pipe to conect the two? I was thinking maybe putting some of those strigth thru mufflers on it, is it gonna be too noisy, would the inyection sistem make up for the richer leaner condition? Finally am i gonna gain anythig doing that?
