Will the BMW GT4 Midpipe connect to a M performance exhaust?

[godkin826]

Hey guys, I am just curious if anyone has any experience or videos of an exhaust setup that has the catless GT4 midpipe going to a BMW m performance exhaust?

Talking to a guy online with a system for sale and that is what he says his setup is but I can't find anyone else online with that same setup

according to the parts diagram, the m4 gt4 uses catless downpipes, stock secondary cats and a no muffler section. the midpipe I believe is all titanium like the gts m4.

so I'm not sure what the guy is selling. the m3/4 has 2 primary cats, then bolts to 2 secondary cat, then a midepipe to rear muffler section. after the secondary cats is where you cut to install the m performance exhaust or gt4 exhaust.

the m performance muffler does not bolt up to a gt4 midpipe as the flange section is different between the 2
