M5 Exhaust on a 2012 550i M Sport?

Need some technical insight. Will the exhaust system (cat back) from a 2012 M5 fit on a 2012 550 M Sport? Thanks in advance.

It should fit. Remember that the engine in the F10 550i is basically the same engine as the F10 M5 but detuned so the diameter of the exhaust should be the same pipe wise as both are V8's. Changes are likely due cat back and muffler back on the M5 vs 550i. However since someone has already easily retrofitted the M5 mufflers into their 550i and used the OEM rear valence it should NOT be too easy to do the full system. Check around some more and I am sure you'll find a willing shop/tuner shop. Dealer will likely balk tho as if anything goes wrong they won't want the blame..however it does depend on your relationship with them tho. Good luck and keep us posted.

Did you guy confirm if the M5 exhaust will fit a 550i F10?

Akrapovic does not offer an option for the 550i F10 only for the M5 F10, I'd like to know what things will I have to modify besides the diffuser in order to fit it in the 550i

should be a direct fit with very minor adjustments most likely between down pipe and exhaust.

I jumped into the pool and ordered the Akrapovic evolution M5 F10 system even thouigh my car is the 550i F10.

As I see on these pictures there will be some modifications but it should work ok if I change the rear diffuser for the M5 one.

It works, I have it on my 550i. The competition pkg is what I have and boy is this thing loud now. Thinking about putting on the primary muffler back on to tone it down some as it's giving my GT500 a run for it's money.

You'll need to have a shop adjust the downpipes and move the resonators back some to clear the transmission. Then you'll just need the M5 diffuser, insert and bracket which holds the trunk proximity sensor.

Exhaust

Most definitely. I have an m5 exhaust on my 2011 f10 550. I am even using the stock diffuser. Muffler shop can make it fit.

Do you have the complete catback system?, do you know what does the muffler shop had to do in order to make it fit?

Bolts up to the stock downpipes. I am using the M5 xpipe but you don't have to. Muffler shop said it was a bit of a pia but not that big of a deal. They had to move the hangers and adjust the tips. Not sure what else ... I didn't really ask for details.
