Connecting a Supersprint X Pipe to OEM Muffler

[NotYnohtna5798]

Hi Everyone,

I recently acquired a set of Supersprint exhaust parts for my E92 M3. They consist of the test pipes + HFCs (#980702 & 980722) and the resonated X Pipe (#980703).

I was wondering if there was a way to connect these to my OEM mufflers. Also I’m 99% sure these two connect to each other but I wanted to confirm that as well.

Also, I’ve found connecting pipes for sale but these only seem to connect SS mufflers to the OEM mid section. Do they work for the other way around (SS mid section to an OEM muffler)?

Any guidance is much appreciated.

This is needed and required for SS axle-back connection to a non-SS X pipe...

I believe these are for a SS muffler to an OEM center section. Do you know if these will connect an OEM muffler to an SS center section?

It won't. You need the 644713 X-Pipe to connect to OEM style muffler. The spacing between the pipes on the other SS rear specific X-Pipes is too wide, plus the ends are located differently so you'd need to do some fabbing to get it to work. Something like what this person did:
