Default Is it worth getting an uprated Exhaut Manifold

Hi guys just a quick question

ive got a 2001 WRX, Im planing on getting a decat up-pipe in the near future and was wondering if it was worth goiing for a complete manifold?

my future plans are as follows
uprated fuel pump
STI injectors
STI intercooler
VF24 Turbo
Intake Raiser
Silicon induction pipe

I allready have ppp Y pipe
3" exhaust system with full decat
but thinking of putting a Prodrive cat back on once the up-pipe has been replaced

whats peoples thoughts here, any input would be great

thanks
Rob

I think it is worth while. I did the usual first mods, turbo back exhaust, fuel pump, induction and remap. I didnt break the 300lb ft barrier so fitted tubular headers and went straight past it.

Harveys headers are meant to be just as good if not better than tubular headers if your running under 400bhp. I have no experience with them but the people I know who have them dont regreat it.
