n54 smoking on decelaration

Just go single turbo or mmp stage 3 twins. its not that much more money!
and then your car really becomes a MONSTER!

I would love to... Although its about double the money over stock replacements...

Off topic but I'm planning on doing my exhaust the same as yours. Any sound clips of it bud? Thanks and hope you sorted asap with regards to OP

I just want to update and close this thread.

Turns out it was then turbos - had them Redone and now the smoke is gone!
