Dave Barton was running the unit that ADP Turbo sells. Looked to be much higher quality than the one I've got on my sedan.

However, my engine certainly isn't 300ponies.... can't speak for his B21. Still, a nice quality 3" high flow cat.

I used this before, pretty inexpensive at $99.


But I prefer this one in SS if you only have a visual emissions check:

My setup uses a 3" Carsound which I believe is a Magnaflow brand if they even still make them. It's the same one on there since 2003 when I got the system. Last time I had to check emissions it still passed even being over ten years old.
