When I went to my local exhaust place to get them to take my M Performance Exhaust off my F20 M135i and replace with stock they weren’t interested as not enough profit in it apparently for them! We don’t have res boxes on uk versions I believe but there is a guy who is well known for modding BMW backboxes but is all done pretty much under the radar to maintain warranty OEM etc. Cheap start to things and if doesn’t work out then nothing major lost so think this will be my first port of call. |

F20 M135i was a hoot. It's the first car I have owned that I really didn't want to see go back. I had the M Perf Exhaust too and the sound was amazing especially on cold starts in the garage. Ultimately it was quick point to point but on most of the country roads round where I live it would get unsettled at speed quite easily. Fair bit of understeer on entry but the fun was to be had in getting your foot down on exit firing yourself up the road. Michelin PSS were amazing tyres. 14k out of the rears with a lot of punishment is pretty good to me! Once they had a bit of temp in them the grip level just went through the roof but to me this could only be achieved when it was around 8 degrees or more. Any less ambient temperature and I just couldn't get heat in them the same.... Have two little kids with car seats etc and trying to get all the kit in for one day a week for the school run was a nightmare even with 5drs. This was kind of what put me off getting an OG M2 as a daily in the end but time will tell if I made the right choice or not.... Car never missed a beat and still got attention at 3 1/2 years old. Always put a smile on my face starting the engine and having the car wobble from side to side! Made it feel like an experience in a weird way....... |

The M2 would be worse as it's a 2 door but a great car.. it is such an experience to drive! I miss my six cylinders however after getting an exhaust on mine and having to hear the true exhaust sound, the car is much better to drive especially when it does little pops when changing gears at low revs and letting off the gas at about 2.5k revs. |

So I’m sorry that I’m posting here because I have a F44 not a f40 but they are basically the same car. My exhaust system looks exactly like yours. I don’t know if that’s the opf or resonator but I deleted it together with the muffler. The car had pops and bangs stock but now it’s wayyy louder. Only thing worrying me is I got a CEL but my car is a 03/2020 so it’s before the dme lock. I used bimmerlink to code it out but it comes back every few days with this error. If someone could help me with this I would appreciate it! I’ll try to post sound clips for you guys.

I still have the stock cat in. Car isn’t tuned or anything. The person who made my exhaust said there where no cables connected to it so it didn’t have any sensors. Idk why I’m getting the CEL, when he said I’m not supposed to get any error code🤷.

Jumping under the car, mine looks exactly like yours and had the silencer had part # 8619455 and the shorter cylinder was #82192830 which is a catalytic converter. Took me awhile! Last edited by Nikysan; 02-27-2024 at 01:58 AM.. Reason: Fact check update |
