I've got a pair of 17747 mufflers behind a 496" and full seperate 2.5" system.
Idle was a bit too loud for my taste so I added resonators.
Want to add an X or H as well to tone it down a tad more.


On my daily 318 Dart I'm (was) running dual Super Turbo's.
One of them literally blew apart after and exhaust backfire so I mounted a regular muffler which was slightly larger.
I actually like the tone of the car better now, eventhough I would like to have a bit more grunt at firm accelerations. But that might be an engine thing.
