One last piece to my mod puzzle before I go for a tune. HFC's.

Preferably resonated since my car is already a rumble monster with CAI, an M370 manifold, and CBE.

I wanted to see what you all had and what your experience is with your HFC. I'm looking for performance, not sound.

Thanks fellas!

 

i have Berks...felt the difference soon as the put them on!!

 

Berk here also. I haven't tried any other but have no need to swap them out since they perform great and don't care for test pipes. If I really felt compelled to change them, I'd go with Motordyne's ART Pipes though just for the added performance and sound combined with my M370 and E370.

 

Went with FI's RHFC's (Fast Intentions) for a few reasons:

-2.5" piping which will make my system 2.5" straight through from headers to my Ark GRIP CBE's
-Resonation (no nasty rasp that I am hearing on other non-resonated makes)
-Proven track record. I had a complete FI TP and CBE system on my old G35 with never an issue.
-Customer service. Both Tony and Blake are phenomenal to deal with.

 

Went with FI RHFC's also for same reasons.

 

I went with FI HFC for the same reasons. Fast intentions customer service is top notch and is one of the best companies I have ever had the pleasure of dealing with.

Get in touch with lance (1cleanG) on here for all your fast intention needs and questions.

 

I went with FI RHFC's also. Couldn't be happier with the sound and performance. Just need a tune now...

 

The Berk HFC option is a great way to go. We just received our shipment of these.

 

Thank you all for the business and support.

Tony

 

I have personally used the FI RHFC on my 08 G37 and they everything they are claimed to be, FANTASTIC!! I will be getting these for my 2013 G coupe soon.

 

YA...cuz your gthaus needs moar loud


right?

 

pssssh that man is never satisfied, he wants moar loud and moar low.

i too have FI RHFC, and although i cant tell you how much of a difference the cats alone made, i installed the cats and full catback exhaust at the same time, i definitely noticed a difference from both of them, and couldn't be happier. Tony didn't disappoint!

 

Before my car was supercharged I had FI RHFC's with R2C intakes and ARK catback. The car sounded amazing better then it does now and you could feel the difference between stock cats and these ones. The only downside was the droning, if this car wasn't my DD I wouldn't mind but I just don't want to hear that all the time.

 

These cats are the only ones I would add to replace my stock cats and gain just a little more sound. Anything else I feel will just be overkill.
