Hello, F30 335i owners,
What's the most reliable high-flow downpipe for the F30 335i with the stage 2 Bootmod3 tune? I've been looking into the Fabspeed catted downpipe, the ER catted downpipe, and the AR design downpipe.
Before anyone says anything about going catless, I don't want to do that because I already have the Meisterschaft SGT exhaust (no muffler nor resonator). I'm going the high-flow catted route to avoid sounding like a complete a**hole and to avoid the awful smell from going catless. If anyone has any of these downpipes on their F30 335i, please let me know your experience with them and their reliability so far.
