that bigger muffler sounds to me like what's commonly known as a muffler, forward exhaust assembly, or more factually as the Resonator.


At the end of the exhaust, just before the tip is the actual muffler, aka the "lunchbox". If you take out the lunchbox your exhaust gets louder, you take out the resonator and it sounds comparitively the same. But as I said most people incorrectly refer to the rear exhaust assembly as a resonator rather than muffler.

... also, cutting the lunchbox out is a common exhaust modification for sound.
