Dear all,

I recently purchased the AA resonated single mid-pipe for my 2019 BMW F87 M2 Competition.

I’m now thinking of adding the M Performance exhaust and was wondering if I can do this without having to cut the MPE to cater for the set-up as I had to cut 1” and 6.25” from the original back box to fit the AA mid-pipe.

I’m reaching out in the hope that someone can let me know if this is possible and also your advice on the set-up that I’m planning which consists of OEM down pipes, AA resonated single mid-pipe and MPE back box.

Thank you.

Sorry but my last sentence referring to my current set-up is OEM down pipes and rear exhaust with AA single resonated mid-pipe.

My setup was OEM downpipe with MPE then added the AA single resonated midpipe later on. My OEM midpipe was cut to accommodate the MPE but the MPE does not get cut ever.

The MPE connection points actually won’t reach the connecting pipes. The previous owner of my car tried to scab in a short length of pipe to make up the difference but it was a leaky mess. I chose to extend the connecting pipes via welding an extension.

I did exactly what allinon72 did as well. Weld extension piping to the AA link pipes to utilize the MPE clamps. My pipes were able to connect, just barely, using the AA provide clamps but wanted a more secure connection.

Mirroring what others have already stated: you need connecting pipes to mate AA EL to any back box. They normally come with your AA mid pipe purchase

Here is my AA EL (non resonated) connecting to Dinan axle back.

I highly recommend paying a small fee to have a shop tig-weld all connections. The brackets are at best a temporary solution and you will have exhaust leak.

AA EL midpipe mated to a Dinan rear section with custom piping. All TIG welded.

Sweet - that is exact same setup up mine. Due to Dinan's larger pipe diameter vs. AA's, my shop had to use a reducer too...think the delta is like 0.5" larger; certainly the tig welds are MUCH cleaner than mine. Not that it really makes a difference, since I'm under my car ~ 2/year; as long as the welds are solid and don't allow exhaust leaks, all good.

The shop is top notch - master welders!

P.S. can you post other shots showing different angles for the AA - Dinan mating portion?
