More exhaust sound needed... F10 550i

Hey fam.

So I want some more noise, but not a nasty, drone-y noise, ya know?

What're my options if I want to keep the original 550i exhaust look, but want some more noise?

Muffler delete? If I swap mine out for the M5 mufflers, will I be able to keep the 550i exhaust shape?

What would yall recommend.

Thanks

if you swap out for m5 mufflers then you can either take the quad tips and leave those on and then replace your diffuser for any diffuser / bumper adapter with one from an m5.

you could probably cut the quad tips from the m5 mufflers and weld on the exhaust openings from the 550i exhaust.

make sure you get the m5 cross member and bushings (that bolts to the frame/exhaust towards the center of the car) which eliminates droning.

Do you have a pic of this M5 cross member? I know my 535i came with a rod that connected the two original pipes before I cut them out and did an X pipe all the way to M5 mufflers.

My understanding is it has a reduced drone as compared to a straight pipe, helps with airflow, and overall helps with breathing
