I'm back with question:
On EU car with opf/gpf and akrapovic slip on, can I replace the resonator with x pipe, h pipe or straight pipes to have louder sound, without cel/limp mod? |

Thanks for this helpful writeup. Without the OPF it sounds like the problem will still be downpipes. On my OG M2 this was a major upgrade even without tune. I will still do this first. The only thing I don't like about the stock muffler is how it looks.

Hi all,
I've been doing a lot of research in the past few months on how to deal with the OPF. I'm still not clear on a few topics and namely the issues arising from deleting the OPFs... Does anyone have answers/opinions on the below:
I suppose there are a few issues here in the EU with deleting the OPF: 1. Risk of getting errors on the dash / car going into limp mode. 2. Passing inspection. I've been told here in Germany they still don't check exhaust gases, and I've heard of people with the AA midpipe passing easily with a warm engine. 3. Risk of losing your warranty if you tune the ECU. Am I missing something? |

I am in the market for an exhaust setup that won't require a tune. I previously had the OG M2 with only a fab speed sport cat and wished it was a tad louder. Would the Remus Sport + AA mid pipe be what I am looking for? I'm not looking for obnoxious loud but a little louder than the previous setup I mentioned before.

I will note that I wasn't really sure about my feelings on the sound at initial install; I felt like it may have removed some character from the car and had some issues with minor droning at 3200-3700 RPM, mostly in Sport, but now that everything has had time to settle and heat-cycle I've grown quite fond of it; no more droning, though that same RPM range is still probably the worst-sounding on this setup. Anything over that RPM range has been awesome ever since install, and I like the deeper tone on the low end. Edit: Upon re-reading your comment I realized you didn't specify which AA mid-pipe. I will note that I actually didn't mind the stock sound too much and was strongly considering moving to the AA Single until I had some more time with the EL / it had time to settle.

(have currently installed catless DP and AA single channel midpipe, the sound is godly but unfortunately I get limp mode... Even with an opf delete module & a can module to disable secondary o2sensors... going on a roadtrip through europe in a few days/weeks and starting to get frustrated. Bought opf delete module, was a real mission to install them, mounted the mid pipes and downpipes, and still get limpmode because the company didnt state on their product page that the pressure sensors still need to be mounted on the DP pressure pipes for the deleter to work (only on the instructions which are read when installing...) Uninstalled everything except the opf delete modules, got a welder to help me out and mount pressure pipes on my catless downpipes so I then could mount the pressure sensors as needed. Installed everything after all this headache and still... limp mode.) Mad but not much I can do other than continue trying to resolve this however possible. Appreciate you taking the time. edit: only option now would be if a bmw service point could install the NA map on my m2, or I need to get a hold of a jb4/bm3 (no flash since I want to keep warranty) but really sucks since i spent the same amount for the opf delete module and secondary o2 sensor disabler (for the catless DP's). Really shouldve gone for that right in the beginning, so much headache for nothing:/ Anyway wish for you (and everyone with the same issue) a lot less hassle than what I have had to go through and will keep on going through til I get it running properly.
