i just got a new muffler installed on the left side of my car slanted...its a pretty big one and i expected a big sound...when i started it it sounded loud then driving it it sounds so low =[ i checked for leaks and found some...got it fixed but still a low sound...anyone have any ideas? i was thinking it was all the bends it has to get to the left side...its 2.5 piping with no cat...maybe more leaks?
