Bought the BMW performance exhaust...

Keidame · 03-04-2018, 08:47 AM

What's up guys, I finally pulled the trigger on my first car part(s) by ordering the PE from ECS (with the clamps). I was wondering what bolts I need to have to connect the exhaust to the (stock) headers. I don't know if any of you guys have the part number for those bolts, or if you're just going to tell me one of the clamps comes with them, any info would be helpful!
It's a 2011 328i N52 with 84k on the clock, so the bolts will need to be replaced haha
Cheers guys

Use

http://www.realoem.com/

to find the part numbers.

OP,

The only thing you should need is the clamps. The stock headers remain all the way past the cats. From there the stock mud pipe is cut out. The stock muffler is connected so this will come out in one piece. The new midpipe clamps to the cut pipes just beyond the cats and then the new muffler clamps to the new mid pipe. No bolts should have to be replaced.

All you need is a saw to cut the stock midpipe after the secondary cats. Then use the two smaller band clamps to attach the resonator delete pipe then change the muffler

I think Nos. 5 and 7 are what you are looking for:

Most assuredly not. The PE mounts to the secondary cats, not the exhaust manifolds, and there are no flanges at all; band clamps are used.

If this is the oem kit from ecs you should not need to buy anything. You need to cut your exhaust where the performance exhaust connects up and slip on the clamps that are included in the kit.

atmosphericM · 03-05-2018, 02:18 PM

Yup have fun cutting!

Enjoy the exhaust. After a month or two it will sound even better.

Phyrexia · 03-05-2018, 02:58 PM

I'm looking forward to hearing mine once I fix the mounts.

Hey everyone, the part number for the 55mm forward band-clamps (or clamping bushes) is 18307560778 and the part number for the 63.5mm clamp is 18307536425.
