Mount M340i exhaust tips to 330i - compatibility?
Hi,
I am getting my new G21 330i M-sport at the end of October and currently planning all my mods and purchases. Among these are swapping out the diffuser and exhaust tips for the ones on the M340i. I just like the square ones better . My question is whether this would be possible without too much effort? I have tried to do my due dilligence on realoem, but I could use some input. The tips on the 330i M-sport are 90mm in diameter, but what is the diameter on the ones on the M340i? Also, does anyone know the placement of the exhaust between the two, i.e. the length between each tip? I am hoping the this is a simple swap with parts: 51128058659 + 51128058660 + 51128069391. Simply pull of existing tips, diffuser and mount the new tips. As far as I can see, the rear bumper is the same on both, so the diffuser should match. Thanks a bunch to anyone that can help with this! |

Det passar nästan har själv tänk det samma mycket snyggare med m340 slut blåsen, tyvärr måste du kapa slutblåsen på din 330 för dom sitter högre upp på 330 än 340in Får min nästa månad |

Hej! For the sake of everyone reading this I'll keep it in english. So what you are saying is that the exhaust sits higher on the 330i vs the M340i? Do you know by how much?

I would like to know this too Have you found extra info?
Edit: By comparing pictures I would say the exit pipes both sit at the very low end of the bumper. Would just need to measure both of them to see what the spacings are but seems like an exhaust company would be able to make that fit without issue (perhaps a little bit of cutting and welding) if the diffuser and bumper trim are just interchangeable.

No, I have not been able to confirm it yet. My local dealers are also unsure and unfortunately there are no M340i nearby, so I am unable to go out and take measures on my own. As I see it, the exhaust sits further "out" on the 330i, it almost look like it goes as far out as the tips sit. If this is the case, it will definitely require some cutting. In addition, it also looks like the diameter of the exhaust on the M340i is smaller than on the 330i, but again, I only have pictures to go by.
I am probably just going to buy the parts and see if they fit. Mine is a lease, so not really able to cut and weld . |

Not sure if you've done this by now but guy from my country with a 330e did this conversion and said it was basically plug and play in this picture thread:

Quite a chunk of the original pipe had to be cut off. They had a 340i in the showroom which they used to measure How much had to be cut off. Parts needed: -51192455859 : diffusor 340i m perf -51128079607 : bumper bracket -51128093303 : 340i exhaust tip 1 -51128093304 : 340i exhaust tip 2 Love the outcome, pics attached. Few shots of the whole car as well, had the entire m-perf kit fitted. Last edited by Stefferd; 12-28-2021 at 05:40 AM.. |

Hey guys! Does anyone purchase G20 330i M Performance Exhaust without the M Performance Tips, then try to modify it with the stock 340i diffuser set up? I know you might of to cut the Exhaust a little shorter. I think that just save about $600-$700 just for tips.
Let me know what you guys think? Cheers! |
