Can't Decide what HFC's

birdman71

Hey all,
Been debating on where I should go with my HFC's, I know that since I got my car back yesterday from my clutch install that my OEM cats and Pulley system are shot and need to be replaced here soon. Already figured out the pulley system now for the CATS.

Currently running Nismo R-Tune Long Tube CAI with (blown) OEM cats and the FI 18" resonated CF exhaust.

Have had my eyes on these two:

ARK High Flow Catalyzers
Fast Intentions Resonated High Flow Catalyzers

Don't want to do the Long Tube Headers due to the amount of time the car will be down.

Anyone have any insight that may have either of these two HFC's?
