Can't Decide what HFC's

birdman71 · 02-16-2016, 03:08 PM

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?

I had FI RHFC's on my previous 12' G37 and they were awesme. I went with some cheap HFCs for the Nismo and I can tell the difference but I really don't care because the plan is to go FI very soon and I'll be dumping all the NA stuff to pay for guages. You do have an opportunity to be homogeneous with your system by having ALL Fast Intentions part from the factory header to the tips.

Fast Intentions Resonated HFCs, no question about it.

We've been a vendor over on myg37 for nearly 5 years now and over 100 clients w/ them and not a single complaint. If you need any info or feedback on them, there's endless information about them and reviews in this Thread (clicky)

Cats run through a 300 cell catelytic converter followed by an 8" resonator. Its a complete win win product, added gains, no raw fuel smells, and still resonates. WOuld also be a perfect compliment with your current setup!
