The crawfords are the best, but very expensive.

Some mods don't create enough of a difference to notice while driving your car. So, you have to try to buy the best mods... the mods that make the most sense, and hope that all the intangible improvements add up and make your car the fastest on the Net.

equal length does not automatically perform better.

After reading all these pages there seem to be plenty of so so quality headers for a decent price but many questions as to there results
When I was mod'ing my previous B series powered Honda headers and the copycats were always a hot topic --- many of the top dogs had their designs copied and many of the copy cats posted similar results
The one thing that I felt was strong was the sense of community the group had about supporting the innovators ---- the guys who R&D'd day in and day out to better support fellow racers with a proven product and squeezed the most from the given engine line
Right now from my perspective Crawford is the only company pushing the Z this way compared to the rest and so far everyone has agreed they make the power --- I think if Crawford received more requests for a "street" header that used slighty cheaper materials it would go a long way towards proven gains at a more affordable price
They may however feel this goes against a "top quality" image and not do it which is understandable and is their right
I think if I was a S/C'd guy looking to squeeze max power from my setup I would get together with the like minded guys and approach Hytech with an offer to make a good long tube soloution for maximum gains and maybe if enough Z guys asked Hytech could make a less expensive NA version of a longtube they made for the S/C'd guys ---- just my thoughts
There are plenty of "header" designers but Hytech headers always perform extremely well --- having them get into the manifold business for Z's can only be for the better

Edit: GOOD NEWS!!!
I called Hy Tech myself and spoke with them. They have not tested a VQ yet because of the R&D costs but as with any business they are always willing to expand their market with more proven products.
If we could get a test mule for 4 weeks and do a group buy we could theorhetically get dyno tuned long tube headers for less than a set of Crawfords
The trick is we would have to pool our resources as a community and pre-pay for the greater good of the Z community --- For instance if they say the R&D for one month of construction/dyno tuning etc... is 10K than 10 owners could get a set of long tubes for $1000 each ---- the trick is the more people who prepay and are part of the first ever set we get them cheaper
The other small trick is fuel tuning ability --- we would need a Z that was close to stock that had fuel tuning mods so Hy Tech could tune on Church Automotives dynapack
This would be so the AFR's were right and they could be designed to produce max hp once the car was tuned
I know 1000 may seem a little steep but take one look at their product quality and list of clients and I think this would be an awesome project for the board --- especially if the gains were significant over whats available
Maybe someone already has a set of long tubes for sale that I dont know about and if so I appologize but for 1000 I think 20-25whp??? for the mod would make them at least worth the hassle of install. For the S/C'd guys I think the gains would be more like 40-60whp with long tubes but obviously thats guessing
