What flanges needed to fit 135i muffler
EDIT:
Changing my approach since the 128i resonator is a different size compared to the 135i. At this point, I'll need two types of flanges. Anyone know the size of the flanges for:
Looking to bolt on the 135i muffler on my 128i. The idea is to cut my muffler near the resonator and weld a flange on there so I can install the 135i muffler as if it was stock versus having to weld it on. Wondering if anyone know what kind of flange I would need to do that and where can I get one? Last edited by WgSo; 12-01-2021 at 09:55 AM.. |

The easiest solution would be to cut/weld from a 135i mid-pipe. However, the 135i has a shorter resonator and the flange occupies some of the same space as the 128i resonator. So you wouldn't be able to attach it there. You'll at least need to use the 135i resonator as well.
This may provide some useful information: https://www.1addicts.com/forums/show....php?t=1735292

Any reason you want to put in a flange for bolt on? If you want a 135i rear muffler, you can just weld it directly to the resonator output (had a shop do this for me when fitting the 135i muffler). As the other poster said the 135i resonator is shorter so you just cut off the flange and weld direct.

Finally have a chance to revisit this project again after dealing with other things.

At this point, I'm thinking about these 3 options:
Honestly, the third option at this point seems the most compelling because the price people are asking for the entire midpipe or resonator is pretty absurd at the moment. The total cost to get them to work on my car exceeds a custom midpipe, if not matching the cost of it. Another benefit of the third option is I can do a double resonator like how the berk or maddad midpipe works. Quote:
