surely I know that the 135i has a larger pipe... is the 130's exhaust diameter identical to the 128i's ? |

Look up Super Sprint exhaust on their website for 125i, they have measurements for the twin pipes & the single rear pipe.
I posted them in the No Love thread or the No regrets thread. I think it was 50 mm and 70mm

I have a 130i, and the rear portion is for sure 2.5in. I think that is one of the differences with the 125/128i. Looks like the 130i shares exhaust dimensions with the 135i.

it's definitely a small diameter piping 2.25 sounds very close to what i remember what the exhaust guys were telling me when they were ordering piping for my car. If I have time i'll left and measure and let u know.

Thanks for looking into it guys...
reason i'm asking is because im working on a retrofit, but need a temporary solution. hence need to know the exact diameter before ordering parts. |
