Fellow Enthusiasts,

I have been looking to increase my exhaust volume (without a CEL) and ended up looking at different downpipes to install on my 2015 M235i with an MPE and a resonator delete.
I'm not too interested in the power gains since I barely get to use all of it anyways and I am personally not a fan of the sound of a catless downpipe. This also means I don't plan to get a tune quite yet.

So then my question: is the AA downpipe worth the money? Can someone who has a similar set up also give me your experience with it?

Thanks!

Yes, it certainly is worth it. More sound, no fuel smell, and no CEL

I have it, had it Cerokote coated. Worth it ? I enjoyed the extra growl on acceleration, also cold starts. It does nice lil bump in power, plus if you ever tune, its ready. No CEL in 8 months

(I'm assuming you have changed out upper chargepipe piece, stock it can blow, start increasing power like this, def. messing with lol)

Just had it installed and very happy. No drone, definitely a bump in HP. Then I installed BM3 stage 2 (I have replaced charge and boost pipes and upgraded intercooler as well) - absolutely awesome in sport and sport+, BIG change in HP vs JB Stage 1. Wheel spin all the way through second gear and chirp into third (auto with BM3 transmission tune in addition to Stage 2 multi on 93).

I've had mine for over a year and a half. Last 3-4 months with BM3 stage I tune and so far no issues or Cell.
