OP, it's been about a half-year with your RHFC. Still happy?

Any O2 Sensor CEL in the time that you've had them?

Bumping this thread so more people can see the OP's excellent video.

It's been a year since I first asked these questions, and just this morning I ordered a pair of resonated cats from 1cleanG.

I'm loving mine more every day. Mpg has gone dramatically down, however, due to winding it out away from almost every stoplight just to hear it

Hate to bump something so ancient but I wanted to hear some recent feedback. I'm interested in a set of HFC's and hear the resonated version of Fast Intention seems to be the way to go. I'll be ordering probably Thursday or Friday unless I just get huge replies saying otherwise.


In case anyone else was wondering, this is what sold me, watch the whole thing!:

Are you going to be running a stock exhaust or aftermarket?

Mine with the berks and ark inside the car

Thanks OP...I have Berks and will be going to FI this spring/summer. Can anyone comment on the CEL light with the FI on the Coupe FI RHFC ? Will be selling the Berks after the FI install.

I have the FI RHFC with ARK catback no CEL lights and no complaints.


Just curious what would happen if you put a Coupe RHFC on a sedan? Because I believe that's what I have... since mine are 2.5"

the 2.5" is what I would go for on my sedan as well. the ark grip exhaust is a 2.5" system so it would make sense to run a 2.5 hfc to keep flow consistent and keep rasp out of the equation.

i have a coupe's RHFC on my sedan so the 2.5" matches up nicely with my ARK CBE and i absolutely love it

no rasp at all

That sounds beautiful.

Can anyone comment on the sound increase (decrease?) that the RHFC give to the exhaust not compared to a regualr HFC? Maybe a 1-10 scale

Has anyone tried to pass emissions with their HFC's?

I ran both Berk HFCs and RHFCs with my stock sedan exhaust. If 0 is a stock cat and 10 is a test pipe in terms of volume, I would say the FI RHFCs were a 2 and the Berks were a 4-5. With the stock exhaust, the RHFCs barely changed the volume. The Berks were much more noticable but came with some rasp. I went from RHFCs to Berks then back to RHFCs and now welded in a coupe midpipe to give me a little more volume with the shorter resonators. I'm still wishing the RHFCs were just a bit louder.
