PE clamps are not cheap from BMW...

Well it looks from your picture that the exhaust comes with a clamp already in place, so I guess you could use that, or remove the clamp to give you enough pipe to employ the PE clamp.

You could always buy a BMW clamp as used on the PE and fix it that way. The Eisenmann box looks virtually identical to the PE...
My problem isn't the clamps. My problem is that they are no identical. I tried to explain how earlier. If you look at the rear of each of the mufflers I posted, the PE has a bit of pipe at the rear so you can slide it in or over the the midpipe of the car. The Eisenmann muffler has no such pipe - just a hole.

I'm confused on what's going on. The mufflers gets replaced with a cut and weld. If you go a different route they may delete a resonator/box. You either slip it through by having a shop open up the diameter and clamp it, or line them up and weld.

To reduce any chance at leaks, just weld it in my opinion.

For what it's worth, here's a pic of my PE and you'll see there isn't a lot of pipe before the clamp...

To my knowledge the PE doesn't require the res. delete, which is why I'm wondering why the Eisenmann muffler would.

Not a lot, but certainly enough to where it wouldn't require a weld....

I'd like to also add that I would prefer to do this myself partly because there aren't any muffler shops around me.
