BMWPE arrived today.

Didn't have the information about where to cut the pipe. Can anybody help me out with the info?

You have to remove your old mid pipe and place the PE's y-pipe over it and mark where to cut. Its pretty obvious once you hold the y-pipe up to your mids.

Have some sand paper on hand to get a nice clean connection(your old mid pipe will have some surface rust on them) for the slip on clamps. I also used some LiquMolly assembly exhaust paste inside the clamps/pipes.

I reinstalled my N54 mids(with working secondary cats) and used the PE's y-pipe. I really LOVE the way the PE sounds with the N54 mid pipe cats. And after you put a few thousand miles on... the exhaust just seems to get better and better sounding.

false. The 128 has a different exhaust setup than the 135i. you cut about and inch or two behind your stock muffler, line your PE up, slide it over and clamp it down. 128 doesn't have the Y pipe at all due to different mid pipes, so its literally just a muffler swap.

It's just a muffler back. It makes sense as soon as you jack it up and look underneath.

Finally got around to this after getting back from a business trip to NYC yesterday.

Did a best-guess measurement on the old and new pipe (they're not exactly the same) and it came out fine.

Yeah, you can pretty much just eyeball where to make the cut. The collar included with the kit gives you some wiggle room for fine tuning. And glorious is a good word for the new sound. Just wait until it breaks in a little bit!
