AA Catted downpipe or alternative?
I have a 2020 M340i currently tuned with a stock downpipe. I have ruled out getting a catless downpipe as I don't want to deal with the smell and the significant increase in sound. I see that the AA catted downpipe costs much more than others. Other than not throwing a CEL and better quality, is it really worth it to get the AA catted DP over other catted options if my car is tuned already? If not, what are alternative catted DPs that have good fit and finish?

The MAD catted is an excellent option if the check engine light is not a concern.
its a little louder than AA but everything else is the same

MAD is a little louder from what i have seen, the smell is the same (not noticeable in my opinion)

^ Best of both worlds. 200cel so it's cheaper and louder than AA and it won't throw a cel even on a stock tune. |

The new chassis is much more tricky than the old one, so Active had to upgrade their cats to the newer GESI. The original GESI did not trigger a CEL on the F chassis but was not as reliable on the G chassis. I want to see more customers try the CG precision on the G chassis before I can say it won't trigger the check engine light.3 As a personal choice, if I'm spending $1000 on a downpipe, I'd rather spend another ~ $300 for the guarantee.

^^^^ This! Not always, but sometimes it really is worth it to pay a high premium for piece of mind and quality.

OP is tuned, wouldn't care about a cel, so MAD dp be a lot cheaper, flow better and just as good quality. Why spend that much more for AA on a tuned engine.

if the CEL is not a concern, the MAD downpipe is the best value in my opinion
