Hey people,

I got a F36 428iX Gran Coupe and I'm considering doing the dual exhaust conversion. I'm thinking of getting the AWE axel-back exhaust (https://www.awe-tuning.com/awe-bmw-f32-435-exhaust) that they make for the BMW 435i and in some forums, I'm seeing that you can't install this 435i axel-back exhaust on a 428i. Now obviously I will be changing the diffuser to have exhaust tips going out from both sides, but would anyone know/did anyone install an AWE axel-back exhaust that was made for the 435i on their 428i. Assuming that I'm not chaning the mid-pipe, this conversion should go flawlessly...

Also for anyone who did a dual exhaust conversion for F36's, are there any differences between the exhaust of a 4 series coupe (F32) and the gran coupe (f36)? Kinda new to this exhaust modification thing hahah

Sounds great man!
I ended up going with Remus's dual axle-back exhaust. Spoke with a representative from mod bargains and he said it's possible. I'd just have to get an adapter piece or weld the axle-back to the midpipe.
