i am running milltek with 100cell catback on my 997TT. thinking of changing the stock headers now. Which header brand would fit/match well with the milltek exhaust.
In terms of performance, which header would give best performance gains?

 

Stock, seriously I doubt there is a whole lot of power to be had with aftermarket headers.

 

Fabspeed are fine...i had them on my 996TT...i have a set for sale if interested pm me...

 

Keep the stock ones on and use the $$$ for another modd. You will gain 6-7hp

 

i'm considering ECU remap. Cannot decide between softronic or APR. Any suggestions?

 

ECU will make a huge difference to the car, both softronic and APR have a great reputation, you cannot go wrong with them

 

Leave it stock until you change turbos. Spend the money elsewhere.

 

Definitely do the ECU first. As for tuners, do your homework. Search this forum. There are several to choose from. Remember, you're not only buying a product but you want to develop a solid trustworthy relationship with the tuner/company.

 

None from what i hear. There have been a few threads on this topic already....no need to reinvent the wheel. Spend your money wisely on something else .
