Had a mid pipe to go with me downpipe and greddy exhaust on my FD. With no cats the car was strong, blew flames, popped, crackles, you name it.

At some point I burned up one of the gaskets on the intake and had a water leak right on top if it, which sucked water into the rotors and trashed the motor.

I replaced the motor and put the stock main cat back on, but its clogged and old, and I want to upgrade to a high flow, so the question is...

What is the best high flow cat for the money?

P.S. I've got PFS computer, intake, intercooler, popoff... and a new motor. Stock twins.
