OK, stock cat is plugging up and is ridiculously priced to replace.

Aftermarket cat considered is RB Supercat, but there have been some reports of the matrix crumbling.

I'd like as much performance increase as possible (I know this will be minimal), no CEL, a more aggressive (but responsible) exhaust note (the rest of the system will remain stock), and reasonable price.

What are my other options?

Is the RB Supercat a decent unit or are there really quality issues?

Thanks, all!
