Selling my Stock GT3 Headers. They were on the car for ~10K No issues just upgraded.. These are a plug & Play for standard 996 3.6ltr. engines and are a good upgrade. SORRY EVERYONE>>> THE ABOVE INFORMATION IS INCORRECT THESE WILL NOT FIT ANYTHING BUT A 996GT3 Thanks
Dave, are you sure that the GT3 headers are plug and play with the M96 motor?
They won't fit. Different bolt pattern on the M96.
wait dont GT3 Headers have the Cat's incorporated into the Headers?

NO.. I WAS TOLD FROM SOMEONE THAT IT IS AN UPGRADE ^^ SEE ABOVE CATS ARE GONE Sorry Guys.. I guess I need to do my homework...
Dave, did you go to a custom headers to straight pipe setup?
PO had it on the car already... I decided I'll never change it back to stock.. Cleaning out the basement.
Dave, that is stunning!
I'd love to hear that!

Dell read below. : ) 996 GT3 doesn't. Dave my bad, I guess I had too much caffeine that day, sorry mate. When you asked I was only thinking in terms of header tubing diameters and said yes that would be an upgrade, totally forgot about the pattern.

From the 993 Board we've been doing NYE Runs.. Here is a video I made from this year... All my track footage has too much wind noise... http://www.youtube.com/watch?v=T6RZsjYlVqI

No worries... Anyone want Stock Headers for their GT3... Any Offer Considered
Rookie question here. Other than looking sweet, what do new or upgraded headers do for you? (scared to ask a rookie question here but please give me an easy time guys.)
You're slipping!

Basic answer is that it increases the flow of air, which is why it is louder. By increasing airflow through your engine (exhaust being the last part) you gain more HP.

Actually I was sleeping..
007DT, thanks ! I get it now, less air resistance = more HP. what are the easiest / cheapest upgrades one can do to a stock 2003 996 engine? to get a little more power?

It's not a bad question, and I suspect that a lot of people buying headers (for any car, not just Porsche) don't actually understand why they can help improve performance. An internal combustion engine is an air pump - meaning, roughly, that the amount of air and fuel you can move into the engine, and the amount of exhaust you can move out of the engine will determine its power output. This is contingent on a lot of things, of course, and the real-life application of this isn't as simple as it sounds. But this is the basic premise and it'll work for this explanation. Increasing the amount of air going in can be done in a few ways. Porting and polishing the intake is one method; a less restrictive air filter is another. Big gains are usually made with forced induction; either a turbocharger or a supercharger. They ultimately do the same thing: compress incoming air to increase the volume of oxygen in the combustion chamber. The other side of the engine is the exhaust. If the exhaust fumes can't get out of the engine fast enough, then you have a bottleneck. A less restrictive exhaust will, in theory, help this problem. Without getting into a long-winded explanation about back pressures and unburnt fumes that get catalyzed and other exciting details, suffice to say that a header is typically less restrictive and *can* (but is not guaranteed to) improve performance. This comes with many caveats, of course - not the least of which is that any modification to the vehicle *will* have consequences. People have been debating these pros and cons for as long as vehicles have been modified, but suffice to say that there's no do-all "magic bullet" to make the car go faster and still maintain its reliability, longevity, durability, etc. When you get more power, you're almost always giving up something else. It's up to you to decide if that trade is worthwhile. By all means, look at the bits and pieces available and do what you like. Just go into it with both eyes open and realistic expectations. Cheers, -- Mike
