Default Best Universal 2.5" High-Flow Catalytic Converter?

What are my options?

I know Dave, from SMSP, used to sell the 300 cell spun version, but as I found out, he no longer carries these.

Carsound #93506 sounds like an alternative, but most stores don't ship to California.

Any other ideas?

Thanks for your help!

Im not sure on car sound, but I figured i'd chime in and say I had a 2.25" Catco universal high flow, it was great to start with but within 2-3 months the honeycomb broke apart and clogged the exhaust up and I had to gut it, I sold the car shortly after before I found a replacement so I never had a decent universal lol Just figured i'd warn of that one. It was model 6005.

I'm running a Vibrant Performance Spun Metalic Converter. Zero rattles or problems so far.

How long have you been running the Vibrant? I've heard some cats on higher output motors tend to burn out pretty quickly.

Why not run the SMSP 200 cell?

Thanks for the input guys! I ended up buying a 300 cell spun metal core catalytic converter from John at Hytech Exhaust. Here are the specs:

Inlet Diameter - 2.5"
Outlet Diameter - 2.5"
Outer Shell Size - 5.25" O.D.
Overall Length - 10"
