My bro's exhaust is just about done on his 300D, it has been ghetto repaired twice and a few weeks ago another piece fell off. I'm fixing it real-deal, its getting a brand new center section and MB rear muffler on Saturday, full stock system, a thing of beauty!! It wasn't easy finding the rear pot, just about everywhere is out of stock....I managed to find a genuine MB one for a pretty good price.

Personally I run a straight pipe.....
