hi all, I'd like to upgrade the headers on my specC and I'm just wondering what's my options? does every equal lenght manifold will fit or does it have to be for twin scroll? do I also need to change the up pipe and again does it have to be for twin scroll?
Thanks

 

Stick with the standard stuff, it works well and has been tested to over 550bhp

 

thanks for reply, I'd like to get mine ported and heat wraped so I was thinking to get any replacement for that time while I'll be doing that so tbh I don't mind to stick with the standard

 

Not much to be gained by porting TS manifold and not a lot of material too start with I would leave them alone.

 

I need to take them off anyway to get access to engine mounts so I thought I could do some work on headers.

 

Have your heat shields rotted off if not leave well alone. If they have just wrap them and screw them back on.

 

Your existing setup




Pointless changing it, and yes it has to be for twin scroll.

 

They're in good condition without rust or other damage, thanks for your opinions I'll keep them as they are.
