Questions: Aftermarket R18 Pulleys and Headers

I'm looking to purchase after market pulleys (please don't recommend NST - long story short, I ordered them in December and they never arrived. My bank is helping me get my money back) as the NST ones have quantifiable gains.
Are there other brands you can recommend? Maybe I haven't researched hard enough, I've only found an AEM pulley set, but that's about it.

Also, what are the benefits of after market Headers for the R18? Anyone have experience using it? Does it need to be coupled with a high flow cat/exhaust system to realise the benefits?

Thanks in advanced!

Ralco make a set for the R18. Apparently they're a reputable brand in the Nissan scene.

You can't get a header

This is just my ignorance, but one of these can't be fit into the R18?

mmm putting it that way , arguably it is a header.

It probably won't do a lot without changing the whole exhaust out and changing the cats

Thanks! :)
Yeah, a couple of Honda forums are questioning their reliability, but nothing concrete to confirm they're rubbish. I think it's a bit of an unknown brand to Honda drivers.
There's a bit of a debate about the impacts of no dampener on the crank pulley wearing it out over time.

If you pop onto 8thcivic, they actually talk about this particular header. They say it's more of a downpipe? I only had a quick read about it. Plus it removes the cat converter, so that's a no go for me.

IIRC that's the weaponR one

Oh I didn't realise the cat converter had to be removed :\
If that's the case, then that's a no go for me, too.

Yep Cat can be removed and replaced with a Turbo B-), my Civic came third today at Marulans DTC first ever proper time attack, got pipped at the post by a built RX7 FD3 and a Targa Tassie R33 GTR.

Saw the post on BYP Racing, Nice job man!

Yeah Sharkchu the Civic did a better Job than I than I expected, Marulan is such a tight little track, beat half a dozen Evo's and Rexy's and a bunch of Turbo 5's so I was chuffed. Still had a 25Kg + towbar attached so I'll be ditchin that next Shootout. Buladelah Hill climb in a fortnight, plenty big power MF lining up to attend, should be fun.
