I've got a remapped 996TT with a Fabspeed Gen3.
Will upgrading the headers make much difference?
If so which ones should I go for

Cheers

 

from what I understand if you have K24 they are good but if you have the k16 there is no big deal

 

Not worth the time or expense. Save your money for other mods.

 

revisit that when you get to the 700whp level....

 

been covered in exhaustive detail. Stock headers are better than aftermarket
until you get to some *very* high power levels.

 

Diveextreme had ported stock headers on his 01 turbo with close to 1000hp.

 

Headers, like many above have said, are not much use until at least 550whp.

Your next mod should be a new set of turbos and a new map.
I know some have run rediculous power levels without headers but that does not mean that the right set of headers would not have helped at those high levels.

 

not sure of the power, but i have evo headers on my car, and it changes the SOUND dramatically...

 

Scot had stock headers to 700 whp or so when he was at 1000 hp, and running external waste gates he had to go with aftermarket headers.

 

For entry level istis really not required... get a flash...
but if you do here is something to look at... hand made from scratch per order.

I have Evoms and they don't make much more power (if any) than stock exhaust. Sound and look better. Perhaps in high HP applications they are more useful. After spending my youth shoehorning headers into various muscle cars, this was too easy a mod to resist.

 

A good read....https://www.6speedonline.com/forums/...ers-truth.html

 

I saw the car with the latest setup on my hoist and it had stock headers with external gates.

 

You saw scotts old car with stock headers and external wastegates?

 

definitely not worth the money at your power level. like others said, revisit when and if you go for more. Good way to look at it, is if you go bigger injectors, you are now going much bigger in power, so it may be time. But I do remember the porting stock headers trick. Great idea for much less.
