M2 N55 Valvetronic Exhaust Retrofit to 135?

rexlex · 08-31-2023, 09:11 AM

I have a buddy that has a N55 Valvetronic exhaust (https://valvetronic.com/products/bmw-f87-m2-n55-exhaust) that was used on his old M2 that he no longer owns. He is willing to trade my detailing services for this which I find very attractive. I was wondering if anyone here has done a retrofit to a N55 135i and if it is worth thes modification cost to take this full catback exhaust. Thanks!

Start looking for threads where people have converted to the 1M style exhaust.

The shape of that one's nothing like what you have now. At a minimum there would be changes to the trunk, the rear bumper, etc.

"Worth it" is totally up to you.

Yeah I figured some modification but if I have to re do the rear and like I was making a 1M clone then it might not be worth it. I don’t want to have to move the battery and tray around, while not hard just a pain in the ass for a free exhaust.
