Aftermarket Headers

[halberd]

I've got an extra bit of cash floating around and wouldn't mind getting hold of some, but;

Is the difference over the stock headers worth it?
Are the cheap one's crap?
Are they a nightmare to install?
What should I look out for when I'm buying them? (I've seen the thread about the 4-wire O2 sensors, I know I'll need to that probably)

I really know nothing about exhaust systems, so cheers in advance for the advice guys

I would advise that you stay away from cheap ebay/trademe ones. I had some cheap ones and they kept splitting and getting rewelded over and over until I stumbled across some quality ones. Also, do NOT wrap them with heat wrap, they will corrode and give problems. If you want to keep the heat down then coat them with hpc.

Regarding the difference, I remember that it felt noticeably more rev friendly, and more audible, especially when the cat was removed. Should be more noticeably with forced induction.

If I was you I'd try get a quality second hand set from Japan via yahoo auctions or one of the many guys on the forum.

Ok sweet, thanks for your help!

you need to buy a heated oxygen sensor when fitting extractors so add that to the install cost too.
