[midnight.240i]

Been thinking about getting my center section of the exhaust removed so its a straight pipe flowing into a twin pipe from the downpipe to the back box.

I've been to a reputable company who did the inspection and couldn't guarantee the car wouldn't go into limp mode because of the change in exhaust pressure etc. and the car being basically brand new. its a 2024 240i xdrive with all the new interior, new software...

Has anyone done this yet? did they have any issues? I don't want to map the car or do anything else really power wise just wanting a bit more noise...

UK spec car also for info

Any help is much appreciated

Thanks

Don’t know the answer to your question but that exhaust part is described as “ RP Gas.particulate Filter W.front Pipe”. *If* it contains the filter, removing it is illegal.

My only question would be why?

Taking a shot in the dark here but my guess is sound + flow improvement.
