Putting M4 aftermarket exhaust on the N54 335i?

z19930612 · 08-18-2014, 03:40 PM

Since my car has the M3 rear bumper so I have to weld on the E92 M3 back box with quad exhaust, And it sounds crap at the moment....
So I am thinking about getting a aftermarket M4 back box and replace the E92 M3 one from my car, looking to hear some advice from here

I thought about 1M back box but the width between the tailpipes is different, so it won't fit into my bumper.

No.

The M4 sounds worse than the E90/E92 aftermarket offerings available and will certainly cost way more than what you can currently get for the N54/N55
