Please get a video when its complete. I'd like to hear this setup, I know there's other videos in existence but I need another to help convince me.

Hey, look at that... the resonators are stamped Sebring Tuning. Were these always Sebring parts, or is that something new for FI cats?



I had the FI RHFC matched up to the OEM exhaust for about a year. You get a little deeper tone, and a small but noticeable added grunt of power. Here's a link to my initial review on the cats:

https://www.myg37.com/forums/build-t...ml#post3752394

Tip: after the install, remove the rubber dampers hanging off your mid-pipes. With the FI cats, those actually *create* vibration, rather than absorb it. Kind of weird, but true.

I don't have a direct before/after on the cats, but I do have a before/after on the cats+catback.

My set (order placed in July of 2015) had the Sebring stamp.

Definitely, I don't think there is one with just RHFC.

Thanks for the tip, I'll keep that in mind. I'll check out that review.

Mine didn't (order placed on January of 2014). That doesn't mean the resonators aren't Sebring Tuning, but it doesn't mean they are, either. IDK

I literally just posted that very thing. The first half of that video is the FI RHFC with OEM catback.

As mention before, there is a small noticeable tone to it. I haven't launced on it yet, from 0. At Wot it sounds and feels nice. Did a video, but its too windy, tomorrow morning I'll do a cold start vid...

Stillen CAI next??

Nice, this is what I am wanting to do but I read so many conflicting things that make me hesitate. I don't mind the slight increase in tone but I just don't want the smell or rasp and I was concerned the FI HFC don't have mounting brackets.

Is the power increase noticeable? I just did the Takeda CAI and now I am wanting more power...

There is no smell. These are catalytic converters, not test-pipes.

I wouldn't say there is no smell 100% if you stay stopped at a light long enough you'll get a little bit of it but not as bad at test pipes.


I get more of a smell since my RHFC decided to **** the bed

Although its probably too early for me to say this, I haven't smelled anything too.

Sometimes after I park my car, I get a burned oil or rubber smell, happens every now and then and especially noticeable in my garage. Because I work in sales, I don't want any smell in my car and I can't have loud exhaust tone either. A decade ago, I had a Supercharged RSX-TypeS with full bolt ons, those raceheaders made my car stink. Wife hated it.

What happen to your RHFC?
the honeycomb inside the cats went bad or something. when i m stopped and start to accelerate it rattles/rasps. you can really hear it in a drive thru.

But when the cats were good it sounded beautiful. I might pick up some Z1 HFC since they are cheaper and throw them on since i did the RHFC not too long ago and the bolts wont be too bad this time around.
