4in vs 5in exhaust. Yes i know another one.
I know its been covered to death but i couldnt find quite what i was looking for. How does a 4in straight pipe compare to a 5in with a resonator/muffler. Im mainly concerned with the drone i really dont like it. As far as actual noise well, currently it has a 3.5in straight pipe that exits right...- Daniel McCurdy
