I would like to eventually add HFC to the car but want the best option that won't cause rasp or crazy noise. What's the best company to go with in that regard? Gains/minimal noise.

Thanks

 

Gains are about the same across the board for HFC. Cell count and design will determine how loud each will be. Gains are noticeable, even more so with a tune but I would suggest staying stock if you are picky about sound.

 

I think Fast Intentions is your answer. Their Resonated HFCs are awesome.

 

If the noise is a issue I would say FI RHFC. Do you have or are you gonna put CBE? This would make a big difference in sound also.

 

I plan to add a ypipe and I already have the Sport Muffler as an option, so it's much louder as is. I just don't want vibration or any obnoxious sounds. If it makes the setup a bit louder then I am fine with it.

 

Has anyone heard FI RHFC with ark grip catback? might be getting a hfc this week and M370 manifold.

 

Have the E370 with FI RHFC's... M370 and tune next weekend! Pure awesomeness is all that I can say

 

What are the true gains of getting HFCs on our Gs.. All else is stock?

 

I would suggest looking at FI RHFC also. I have them on my G along with their Traditional RCBE. Awesome sound.
