^^Well for one thing Stillen doesn't make a CAI for the G37. Maybe that is why he didn't answer. The Stillen intake does make power for the G37 at least until it gets hot in the engine bay and then I hear it losses power But since no one has a dyno showing this it is still speculation. Proof needs to be submitted.

Nah, that's no reason to just ignore the issue and fail to answer a simple question for a potential customer, IMHO. Oh, well. They're a large company. It happens.

Hey Buddy, I apologize for not replying to your question earlier.

I know that independent testing and experiences are key when it comes to product reviews so I have been researching customer's experiences with our intake. Here are a couple of threads that discuss the intake's...

This was a test of ALL of our products...Intake, exhaust, HFC's and headers...

Again, I apologize for the delayed response.

Thanks for the info, Kyle. I'll read up on those links you posted. Did Import Tuner not get any gains with your intake or did they just choose not to test it for that article?

I didn't want to post a new topic, but need a little direction.

I can't find anywhere where I can buy the FI HFC's. Do I need to PM Tony or is there a vendor that is selling these.

whats teh difference beween hfc's and a regular exhaust system?

HFCs are cats... Exhaust system on our cars are X or H or even Y pipes... a mid pipe and rear axble back pieces with mufflers...

For HFCs ... Id go with Berk HFCs or you can go with FIs which are 99% the same thing.... choice is yours... I personally Have BERKs..

Exhausts... Id go with Borla exhuast for power... should 18rwhp on my car on the dyno ... and if your going show...go with Tanabe or FI...Tanabe being an axle back and FI being a catback.....choice is yours... I personally went with Borla for a certain reason and I love the Power it yielded... I also had the Stillen exhaust...I like having the best exhaust out... may change again pending on a companies decisions... but right now Im loving the Borla Power and Sound...

IM me on AIM if you have more questions... bbeeler12... Ill tell you more about what is what and what to get

Thanks to you all.
I just purchased FI HFC and scheduled the installation this Saturday.
I also call my Dyno shop where I originally got my stillen intake/cat back exhaust dynoed and set up the dyno afterward.
I'll keep you guys posted on how FI HFC will increase performance.
I hope see 7~9 HP/TQ increase but will see.
I believe this will be a first independent dyno on FI HFC.

congrats!

bboysteele had double digit increases on his HFCs and saw nice increases across the bowerband and under the curve. You'll be happy with the power it produces for sure!

Thanks.
I hope so too.
Will see this weekend.
