2009 Saab 9-7x Aero with 6.0L LS2, all stock (for now)
Before/After Magnaflow 12259 muffler Installed and resonator deleted.

It didn't sound terrible stock but now it has a deeper sound that you can feel and it sounds a lot cleaner. Performance wise this is a wash, maybe shaved a few pound, the stock muffler was huge.
