135 exhaust onto 118i

RobbyF40 · 11-05-2022, 05:26 PM

Hi all
I have a 118i and i'm wanting to fit a 135 exhaust onto it purely for looks.
I know it'll fit as i've seen the youtube vids but was hoping for some info on a couple of things.

1. Diffuser - i'll be fitting a 135 diffuser with the twin exits but have read various things - some say the bumper has to come off to remove the old 1 and some say once the fixings underneath are removed it can be pulled off 1 clip at a time while still on the car?

2. the 135 has a flap - how do you keep this fully open?

3. does the centre pipe also fit from the 135 or do you cut the pipe near the backbox and fit a sleeve?

Thanks

Hey, I have a 116i, basically the same as a 118i, but just coded so it has less power. I have an RCP m135i exhaust on it, and it sounds amazing. I do not have the m performance diffuser, but a maxton design one. The flap is not an issue since I have just removed it. And about the centre pipe, I have cut it and used the regular one and only added the backbox. Hope this helps
