Is the mid pipe the same diameter as the stock mid pipe? The M235 MPE does not have a slip fit connection (relies on clamp) the M240 MPE slips over the midpipe.

Mid-pipe is larger than OE as indicated in an earlier post and slips over the stock muffler inlet being tightened with an 80mm clamp. We base muffler design by set stock points--- one of them being the stock inlet pipe location for guaranteed fitment. If the MPE uses an 80mm clamp as part of its kit then that would indicate that they do the same thing as us --- just in reverse--- assuming you are correct in that the M240i MPE slips over the midpipe. If that is the case it would technically work but would require a coupler and not a clamp to tie the 2 pieces together.
This is all just guesswork though based on loose information since we haven't seen a MPE equipped M240i in the shop however.
