Widest diameter exhaust tips for e46 m3 vert

Haven't begun to research the various options for a full, top quality catback exhaust system. What's the widest diameter unit leading to the widest diameter quad pipes? I love that oversized GTR look and I'm looking for the most aggressive (high quality) system in the market for e46 m3 verts.

I'm guessing Eisenmann?

go custom. your imagination is your limit. typically 83-90mm should fit into the std valance.
you can modify the rear valance, then go for 120-150mm gaping holes. no reason why 200mm tips wouldn't work.

just be careful of people sticking their heads in it, and trying to gas themselves off a cold start.

I just had a custom exhaust done with 76mm dual piping from the cat into 80mm tips. Much better than a standard bolt on stuff imo.

I saw eisenmann makes 83mm. For some reason in the vids the tips didnt look that wide. I'll keep looking.
