Default headers/ exhaust manifold

Is this a worthwhile upgrade? My thinking is that if I can get some for a reasonable price, I might as well fit them at the same time that I fit the u/p and downpipe.

Im getting a remap after all the work is done. Is it worth it with the td04 turbo or should I just leave them as they are?

Or the other option is one of the td04 hybrid things with standard headers!

Properly ported headers and matched up-pipe will give noticable gains in early spool and performance across the rev range regardless of what turbo you are running.
The hybrid 04 turbo is a good move up from the standard TD04 and is capable of 300-320 bhp depending on your spec and mapping.

Here is a link to some tests I did with ported headers :

Hope this helps

Hmmmm why do the numbered links on the right of each post point to completely unrelated threads and posts?

Thanks for your responses. I've decided to go down the hybrid turbo route and leave the headers alone for now (only a matter of time before they have to be ported )
