BM3 E30 OTS Map on stock downpipes

Has anyone here ran the BM3 E30 OTS map on stock downpipes for extended periods of time? If so what are your thoughts on it and have you had any issues? I'm currently on a stage 2 93oct tune, but I can't stand the smell and the sound with my exhaust setup( VSRF+AA+Remus).

We are running this map on the shop's M4 with stock downpipes, i would not recommend it for customer's cars though. But send a log every now and then to PTF and they can check how the car is handling it

Does not smell bad with Stock secondaries in place.....Maybe change midpipe so u can run the e30 map and keep some performance.

I know a few ppl who have been running E30 OTS on M3 Comp Pkg. Being that the Comp Pkg exhaust is less restrictive than Base m3.. These cars have over 2yrs running E30 OTS with stock cats and also still holding 60-130 E30 OTS Dragy Record and daily driven!

Valid_F80 has over 40k miles on his 17' M3 Comp Pkg (The First one to run 7.8s 60-130 back in March 2018)
No smell from his car guessing since the E30 cleans up the bad gas smell but I've also not noticed any smell from Comp Pkg w/ CTS Turbo DP and E30.

Other guys are not on the forum

The Stock Secondary Cats/ Midpipe will remove the majority of the odor.

Hi, is there any cleaning needed when running E30 in the long term? Do you need to do injector cleaning? Is there anything else need to maintain for running E30 in long term? Thanks!

In the past I've chatted with Halim at PTF and he said catless or sport-cat downpipes are only "recommended" but not needed on the Stage tunes. Stock cats flow great.

To protect from people roasting their catalytic converters (if too much burble aggression) I believe they've updated the text to say "required".

I ran Stg2 93 and E30 on stock build no probs.
