I got tired of sounding like a vacuum cleaner so I’ve swapped out my mid muffler for a Flowmaster Super 10 and the rear muffler for a GLI rear muffler. Now I have an exhaust note that can be heard without being excessive, there is no droning, it doesn’t shout out treble, it’s subtle but responsive. The rest of the exhaust system is unchanged, just the mufflers are swapped
