OK, I am deciding on purchasing a test pipe and HFC for my car. Appearntly they are only avaliable for the G37, but I heard from someone that both the G37 test pipe and HFC will fit our 07 sedans. Can someone confirm this for me?

I am leaning more on the test pipe.

here is the site that I will purchase from if it works.

Do you mean Test Pipes OR HFC's? I don't think you can do both. I believe that both Berk and Fast Intentions have HFCs that work with our cars.

 

+1 I'm sured that FI has HFC's for both 07-08 G35 Sedan.BTW Do you mean 300 Cell or 400 Cell..,right?
but this is not street legal? anyone?

Correct, Test pipe AND HFC are both available as posted above. Neither of the two are street legal in California.

 

Fast Intention and Berk's Technology both carry HFCs and test pipes.

But, you can only put either one... NOT both.

 

Terrycs and Blueslate.. Have you try it? I want to try it but not sure if it the 300 cell or 400 cell gonna fit to the stock exhaust.I'm only install Stillen Intake no upgrade exhaust.Should it work..ha?

 

o...icic.....i am pretty new to these...i thought you can put both test pipe and hfc together lol.

i am thinking of the test pipe i posted as above, it will def fit our sedan right?

because HFC is too expensive.

 

so no word if this will fit the 07 sedans.
and if it actually would have any power gains with a stock exhaust.

 

Yes, FI and Berks BOTH fit the stock exhaust. They work by essentially replacing the stock catalytic converters. Both companies mentioned have shown slight HP gains with the stock ECU. Gains should thoeretically be better with an ECU re-flash.

If you do some searching, you should be able to find links to video clips of both company's HFCs installed on the late model sedan. I don't think I've seen/heard one with test pipes yet though.

 

I bought a set of HFC's for a G37 and they did not fit. The upper attachment was perfect but the y-pipe attachment to the base of the HFC was at an angle and 1/4" away from a tight bolt up like the stock cats. I sent them back.

 

Don't do it test pipes make the car sound raspy but you will definately turn heads. People will be like WTF? is that but in all honesty it doesn't make the car sound sexy actually more like RICEY. Only at WOT does it sound OK but come on when you're driving around around 3-4k all you hear is RICEY RASP.

 

I think i will call FI tomorrow and see if HFC'S will fits our 07-08 G35 Sedan
both top and bottom fitment.

 

plus with the test pipes i'm almost certain you'll get the cel

 

What about NYC?

 

Did you purchased from Berk Tech or Stillen?
