2018 F31, B48 swapping to dual muffler

Milkman670 · 05-15-2020, 08:41 PM

So, I know there are lots of swapping exhaust on here but couldn't find this one. Been given 16 m235i n55 xdrive muffler onto a 2018 F31 330i b48 xdrive. Anyone attempted this? Fitment? Sound? Any advice appreciated.

Guess I should give an update. With a little work the muffler shop made it work and I couldn't be happier. Considered cutting out 2nd cat but $$ wise, will wait until I do the catless downpipe and take 2nd cat out then. Also flashed BM3 stage 1/93 and that really improved the sound.

Wowzer. That wagon is stunning! Any sound clips?

Thanks, just a cold start and couple revs.

That sounds pretty nice. Not too crazy but not too quiet either.

Nice F31. Keep us updated once you add the downpipe. Did you tint your taillights?

Yes I did, still have to do rear reflectors and I have new smoked reflectors for the front.

Looks good! I retrofitted the MPE on mine.

Big improvement over the single, couldn't get a good diffuser shipped in, so found a f30 340 rear valance and CF wrapped it for now.
