I know most are probably running a single custom exhaust but I'd like to maintain the stock look with dual angled tips and was considering the standard replacement eBay/IE stainless cat-back system. At the time, I certainly don't want to choke the S52. Are any of you guys running this system?

That's pretty similar to what I did. Ended up going with custom 3" with v bands, a resonator and magnaflow rear muffler. It sounds great but a little loud for my taste. I should have gone with a larger rear muffler but didn't because I thought I was going to use the stock muffler brackets. Oh well.

Zionsville Autosport has a detailed writeup in their Project Orca build (they charge $10 for the info). They use a combination of E36 and E30 parts for theirs.
While we're talking about exhausts, does anyone know why the 1995 325i exhaust that I am working with has downpipes (from the exhaust manifold) that are two different diameters? It looks like a stock system.
