M235i Tuning
Hi,
I'm a new member to these car-forums, but here we go: I've had my M235i since the summer of 2020, instantly put Vossen HF-3's on it (20"), and this is the "tuning" I've done so far: - 2021: I got a tune done by Celtic Tuning (on paper 301hp -> 360 hp, 450 NM -> 515 NM) - 2022: I got a Remus axle back exhaust done, which later got turned into a catback exhaust by also getting the OPF removed a couple of weeks later. -2023: on the 13th I am getting a Cobra downpipe (with a 200cell, so not catless) and an Eventuri intake installed. AMA, ask me anything, and also tell me about the tuning you have done to your M235i's! Just for the record, I do also own a P-Gear -device, and can also provide data from that.

I do, but honestly speaking my iPhone microphone serves the exhaust zero justice. When it comes to the sound of the exhaust, getting the Remus axle back did not really make the car necessarily louder, or I don't at least recall it getting noticeably louder. It rather changed the tone of the exhaust seemingly towards more of a low-pitched sound. Therefore trying to record the difference between that and the stock one was really tough. But there was a difference live, for sure.
Removing the OPF was the REAL difference maker. The car became so much louder. It is like a whole new car, and you can hear that from the loudness of the exhaust, the tone of the exhaust, and also how the "pops" are really amplified now. Also, even with a slighter acceleration, you can hear the exhaust making a more of a raspy sound, and downshifting while going down an even small downhill will almost certainly make a few loud pops. The pops on startup can also now be REALLY noticeable, and they sound really aggressive. I would most certainly get the cat back version of the exhaust and I am really glad that I went back and took the OPF off to make it so. When it comes to the downpipe, I'm not sure how much it will change the exhaust sound of the car. Although, I most likely won't have the cat removed from the downpipe, I'll keep you updated on the sound when I finally get that put on to the car. P.S. I'm not a native in English |

And I can say this confidently since I was also browsing the web A LOT and listening to many videos of the exhaust and how it changes with different aftermarket ones - so trust me on this.

Yeah I get what you’re saying mate, do you still have any videos just by chance I’m just trying get a gist of whether or not it’s worth doing as your car should sound similar to mine with you being from Finland

Has anyone looked into Future Design's aero kit? Judging by the pictures it looks fantastic..https://cargym.com/products/bmw-2-se...-future-design
Thoughts? E: Especially the rear diffuser is crazy-good-looking! Last edited by mandariinimake; 07-19-2023 at 04:27 AM.. Reason: x |

Hey, sorry to bother. Can you please tell me what downpipe you went with for the BMW F44 M235i Gran Coupe ? Like the specific downpipe, the name or maybe a link ? Cause it’s very hard to find down pipe information on this car. I would appreciate it a lot if you let me know, thanks.

Thanks for the head ups. If i get the sports cat, thats to pass emissions ? And if i get the de-cat that’ll give me more performance supposedly but I won’t be able to pass inspection basically ? Is that how down pipes work ? And what does it mean to remove your OPF ?

Did you manage to code out the opf? Surely when you remove the opf it displays a fault on the car |
