For a very limited time Fabspeed motorsports is offering a forum member special on 996 and 997 Turbo headers. There headers are in stock and ready to ship, they include everything needed to install on your car to avoid any potential down time.


Specs:

• <LI class=font15>Fits all 996TT/X50/GT2 Vehicles 1998-2005 <LI class=font15>Copper gaskets included.
• +12HP and + 14lbs of torque for faster acceleration.
• Equal length1 piece C.N.C. mandrel bent headers for all 996TT, X50, and GT2 cars. These MAXFLO headers have a better more efficient primary tube to perfectly match the exhaust travel from the heads to the turbochargers for better boost response and power throughout the RPM range.
• Formula 1, NASCAR, Indy Car style high velocity MERGE collectors for maximum flow. Fabspeed Motorsports headers are absolutely the highest quality and best constructed headers in the world.

 

these look like the ebay/schnell/gmp ones? are they made in-house?

 

Yes please confirm this is not another made in America but actually fully imported from Taiwan case

 

& changing headers, unless you are bypassing a set of cats, which you don't on a 996TT, bring you extremely marginal benefits, there are more effective mods to do

 

Subscribing to this thread. Interested in responses.

 

If you look around a little and do a search you will find that a number of very reputable tuners have stated that aftermarket headers provide zero, zilch, nada improvement over stock up to 800 hp or so and then its still very marginal. We just did a suspension on a 900 hp 996tt built by Protomotive and guess what, it had stock headers. I don't know if they were ported or not but they were stock. For the most part, aftermarket headers are sure to provide a fatter pocketbook to the seller and some bling to the buyer who likes to crawl around and look at shiny stuff under the car. I personally have heard of numerous aftermarket headers with cracking issues but none with OEM. YMMV...

 

i used OEM non-ported headers up to 900hp

 

scott /divex also ran stock headers past 800 whp ....so pwrhound is right,

 

I would love to see independent back to back dyno tests on some headers. Until then, ported stockers for me

 

Anyway Fabspeed made in the USA or not, simple question to answer ?

 

There is a old thread about this where things are made.. Anyway I do not think the stock header will perform as well as a real collector with larger primary's but then on second thought its always tested on a hybrid's that makes stupid back pressure anyway.. So the header is useless and might as well be a log type.

 

i remember that thread, and form what i recall they are made somewhere in asia , cant remember exactly if it was china.... or somwhere else.

 

Lols all the tuners used these cheapies back in the early 2000s and sold them for $1300ish. I had an original set when my car was 1st built that cracked to **** after 4years. i got another set off ebay (paid 150) they looked EXACTLY the same...

and are showing signs of cracking now...

 

This is an interesting thread. I have no perspective on how headers can enhance a 996 TT. That said, I do have lots of experiance on really big horsepower Twin Turbo offshore race engines making over 1,900 HP and can tell you first handed that those motors make just as much HP and Tq with die cast log manifolds as they do with custom fabricated tubular headers. We did much testing and could not believe it. Bottom line the inlet/header side of a turbo is not near as sensitive to back pressure as the outlet/exhaust side is.

 

Hmm..I wonder what BBI has to say about these posts?
