Do Diffusers Made for a 1M fit a 1M "Style" Rear Bumper on a 135i?

highbrowed · 03-24-2016, 12:38 PM

Searched and searched but found no conclusive answer.

Need a diffuser that will fit a muffler with 1M tip spacing (58cm I believe) on a 135i. There are a few diffuser options such as Hartge and Rieger, but they are either prohibitively expensive or NLA.

Wondering if anyone has a diffuser that's made for a 1M fitted to a non-OEM 1M style rear bumper on their 135i, like a Kerscher?

I'm curious as well.

Yes. I had a 1M replica rear bumper on my 135i. I installed a RevoZport 1M diffuser and fit like a charm.

This is a 135i with 1m style rear... it fits

This is fantastic. Thanks for the info, guys.

Interesting that the rear bumper doesn't look as awkward on the "narrow body" of the 135i as the front bumper does. Looks great IMO.

Wonder what this would look like put together with the perf front bumper.

That looks nice! Are the parts as follows?:
- 1M battery tray conversion
- Akra Slip-On axel back
- Revosport Rear Diffuser
- Kerscher 1M replica rear bumper?

So that is a factory diffuser with an aftermarket 1M bumper? I just wanted to be sure before I pull the trigger on buying it.

Nah its a aftermarket diffuser with an aftermarket rear bumper. The aftermarket rear bumper supposingly fits the 128/135 no problem and the diffusers are made to specs just like the 1m I believe. So any 1m diffuser should fit with the 1m style rear bumper.

If you switch the bumper to the 1M style, do you have to buy a quad exhaust made for the 1M or one made for the 135?

If the diffuser is made to 1M specs, do you think you will need a 1M spec exhaust tip spacing, or a 135i spec exhaust tip spacing?
