VOTE--- Fast Intention vs. Stillen
 

A **** load of people take Fast Intention long tube headers over Stillen headers+HFC.
On the paper work, FI long tube headers will gain between 7-15 whp, and on the other hand Stillen headers gain 14 whp, HFC gains 15 whp.
FI long tube headers weights 21 lbs is lighter than Stillen headers and HFC.
The price range is almost the same, $1100~$1300 for FI long tube headers and $1000~$1200 for Stillen headers+HFC.

PLEASE vote the best one out of these two. Thanks Z-guys.

Cannot compare, they are two separate setups.
Fast Intentions are long tube headers v. Stillen short headers.

I vote for full open exhaust, no headers, no cats, no catback.

put a HFC on that short headers, works the same. what is your opinion?

sure, that sounds perfect, but who makes it? i know a friend has the only one GTM 370z supercharge, and is getting the one piece headers all the way to mufflers.

lol

:icon14: ??

Other: PPE Engineering headers in stainless.

Not even close.
HFC still are restricted and the design of a single piece of pipe versus two pieces bolted together play a large factor in why long tube headers are superior to shorty plus other items.

:confused:

I have to give my vote to FI

I heard GTM only made one supercharge for 370z, which my friend has it, and he getting a custom made one piece exhaust all the way from header to the muffler.

GTM has a stg I and stg II SC kit, and they will make as many as people want to buy. There are quite a few out there already, if your friend tells you he has the only one out there then he's full of sh1t.

I found this article. Header - Exhaust Manifold - Tech - Jack Burns - Popular Hot Rodding

I know it is written for American V8s but the principles are the same.

You do not need a custom exhaust setup for a GTM supercharger kit.
I ran F.I. LTH with F.I. exhaust and it sound & performed great.
