Aussie spec ITR headers are rubbbish.... JDM 4-1 work well but abit exxy 2nd hand.
We got one of Dynodave custom headers, it made a HUGE difference over the crappy aussie headers. Picked up over 10kw midrange.

yeah i'd tend to agree....anybody who has seen the AUDM dc2r headers would realise how restrictive they are.
all the headers metioned will be running a 2.5" cat so u will notice a difference in power delivery the motor revs a lot better
are u going for 4-1 or 4-2-1's ?
i have the toda 4-2-1's no regrets in paying for performance and quality
big difference noticed without tuning yet
there is also a brand called maxim works too
Yeap most good quality header runs a step system. We found the headers we have 4-2-1 are very good. Top end is excellent.
Mfactory Header..... LOL
