Stock Exhaust Dimensions?

Perostahov · 01-09-2011, 07:52 AM

Hey guys, I just have a quick question, does anybody know the dimensions of the stock exhaust on the 135i?

like the size of the piping?

Im looking for some shops that will make me a custom muffler delete, but my car is in storage since I live in canada and in the past two days it snowed almost 4 feet.

I just want to provide the shop as much detail as I can to get a estimated price so as soon as this white shit stops falling and melts I can get it done.

Cheers.

BMW starts with 60mm for the midpipes & 70mm for the axleback but because of the crimps and non-mandrel bends they use it is much smaller in many areas.

A fair warning about muffler shops, most of them are complete hacks! In this case it is much better to buy something that is already manufactured.
