F95 X5M OEM quad-tip exhaust retrofit to G05 X5-M50i.... w/ VIDEO!
(edit: Video is post #13 below)
Soooo.... I expected a 2-3 hour job...... and it actually took me 10 hours...... But It's done. A few questions I know will be asked: Yes, the X5M flapper valves are compatible, and work correctly with the G05 Front of axle hangers are identical. Rear (behind muffler) hangers are different. I had to re-use the G05 hangers, and I had to cut the alignment pins off, and shorten the rubber hanger. Most of the under trunk heat shield had to be removed. Much of the plastic surroundings from the old exhaust bezels had to be removed. All underside panels required removal, as did the chassis braces, to get the exhaust in/out. (a lot more work that initially expected) It sounds INCREDIBLE. I'll post a cold start video once it's daylight, and the neighbors don't start yelling at me in French. The day the exhaust arrived on a sloppily built pallet:

up in the air..... old exhaust out.
I kept the double-H pipe I made 2 years ago.... in the car. Resonator is long-since gone.

F95 X5M and G05 X5-M50i flapper valves connections are identical.

I lined the muffler hangers up exa tly in the same place..... by the tile line on the floor.
X5M exhaust tips obviously protrude out further..... which is perfect. Then figured put how much I needed to cut from the X5M exhaust to mate it with my H-pipe.

First (rough) test-fit...... the moment of truth. Will the pipes from an X5M go through the exhaust holes of a G05???
Yes. But you have to remove a lot of the plastic on the inboard side.

As much as I love the X5...... Sorry....
The Alfa 4C takes precedence..... back in the garage. I'll post a sound clip tomorrow..... it's 11pm now. It sounds INCREDIBLE.

Amazing job. I can’t wait to hear how it sounds.
On a side note, there’s a X5M exhaust for sale locally. But too bad I don’t trust anyone to install it but you lol |

Thanks.
There's no way those X5M tailpipes are fitting through those X5 tailpipe shrouds. They had to come out.... no way around it. And I hope I never have to pull another set out again.

I thought about cutting them off and replacing them with aftermarket pipes... but I'll lose the flapper valves if I do that. I welded the flapper valves open full-time on the M50i.... but with the X5M exhaust, I'm now using them again. It's quite a bit louder with all 4 pipes open (Sport plus)... but for daily driving, I like having the ability to quiet it down a little. I will say, that when in Sport+ and all 4 pipes open??? The burbles on decel and downshift and absolutely vicious. Love it.

I used the section from the middle of the car - back.
But the dimensions of the M50i engine are the same as the X5M engine. Intake, turbo placement, etc... all the same. I feel strongly that an entire X5M exhaust would mount directly, including the downpipes. The only "modifications" required.... were to the plastic parts on the rear bumper, to allow the tailpipes to poke through.
