128i BMW Performance muffler install doc?

Ilovemountains · 12-10-2014, 06:21 PM

I have to tell you, I ordered a performance exhaust yesterday afternoon from Sun Motor Cars BMW "no affiliation what so ever" on Fleabay, its in my hands!

It was on my porch when I got home today at 5:30, very very well packed, probably packed by the manufacturer but I'm not sure, no installation instructions included!

Anyone know if they came with at least a guideline to follow?

It looks pretty strait forward but Ive never worked on a BMW, been a Mazda guy for nearly 20 years and really don't want to guess.

Thanks! Matt

I don't have a performance muffler but I remember looking up the DIY awhile ago. There was a good one on this site.

Measure carefully where to cut your exhaust pipe. I marked all around my pipe with an indelible pen (aka sharpie).
Easy to cut pipe with a new hack saw blade.
I couldn't remove star bolt so I just cut the diamond shape rubber mounting. Used a new universal one for a week or so until I bought a proper BMW one for $16 (18 20 7 578 238). You could also just repair the cut one with black tape until getting new rubber mounting (what BMW calls it)

Yours is packaged from factory. When I bought my wife hers it showed up the same way. It's very straight forward. Measure, mark, cut, install, enjoy.
