Hey, I haven't posted in while but I am looking to upgrade my 2016 F82 OEM downpipes and mid-pipes with a high flow setup. Back in 2016-2017, I had catless downpipes but I had to revert that back and never got back to putting my catless back on after doing the first emissions.
This time around, in order to avoid that. I am thinking about getting the Active Autowerkes Catted GESI downpipes so that I don't have to deal with emissions testing in Virginia. I'm also thinking about upgrading my mid-pipes to either the AA High Flow Single or Equal Length. Leaning towards the Single. Currently I have my MPE exhaust that I am very happy with. As I understand, the stock MP has two secondary cats and a resonator. I shouldn't be expecting a CEL after swapping to AA MP? Appreciate any experience/advice. Thanks!

You can touch/remove resonators with no problems.
Only thing that throws a code is when you touch the Downpipes. If your tuned then that takes care of the CEL, if not tuned then Match schnell module or JB4 should solve it. |

Do you think a resonator is needed or I'm good to go with non-res MP?

High flow catted + the single midpipe is an excellent option
i prefer the resonated midpipe for a cleaner sound, but either option would work

I'd go with the midpipe alone and start there. Is there a reason you need to swap the factory dps other than sound?

Would you suggest I go with resonators in case I decide to upgrade the downpipes down the line?

Gotcha. However, the downpipes I mentioned are the High Flow CATTED downpipes from AA.

Tough pill to swallow especially with the costs involved. If you're flashed you won't have any issues with a cel which is the main reason to go with the more expensive Gesi cats. Stick with the factory downpipes or go with a higher flow option and get the power as well.

Currently I am running a JB4 Map 1. Will set it to Map2 with the GESI HF cats and single mid-pipes. I'm also on the fence if I want to get the MHD with JB4 BEF but I'm not certain yet.
