These 304 stainless steel long tube headers are for the 2000-2004 LS1/LS6 Powered Chevrolet Corvette & Z06. Kooks builds all of their products to the highest standard, and these are possibly the best headers you can buy for your Corvette. These emissions style headers (include AIR/EGR) feature 1 3/4 primaries, and 3 collectors with O2 Bugs welded into the merge collectors. With a proper tune at a dyno shop, these headers are good for 20-35HP depending on the vehicle.
To connect these headers to your exhaust, you will need a Kooks high flow X-pipe. These all 304 stainless high quality X-pipes come without cats (off road), or with Kooks high flow catalytic converters. On top of the standard rear O2 bungs, these X-pipes also include an extra O2 bung and screw cap for wideband tuning. The standard X-pipe size is 3 Inlet, 3 Center Section, and 2.5 Outlets to connect to your stock/aftermarket 2.5 axleback.
Which Header Size Should you Choose?
The 1 3/4 headers are intended for bolt on and mild internal engine work applications like a small cam. For cars modified on a higher level like heads and cam, nitrous, or supercharged, 1 7/8 Headers are recommend. If you are not clear on your future intentions, you can run 1 7/8 headers on a bolt on LSX motor with very little change in the power curve anywhere. Choosing the larger header size up front will give you room to grow with little downside in the short term.
For years we have been dedicated to proving our header customers with the best header coating options at affordable prices. Recently our main coater Jet Hot who we have had a great relationship with for years was taken over by new ownership. The new owners have done away with their dealer program resulting in everyone paying drastically higher prices. In response, we have lined up two great competing coating company's offerings for our customers that will allow us to offer the same low prices as before. The coatings all the companies use are very similar, and the main difference is the time an attention put in to doing the job right,
- Airborn Coatings has a history that goes back as far at Jet Hot. Their owner is a chemist who had a hand in developing ceramic coatings. Airborn offer the same great 1700 degree inside and out silver coatings as Jet Hot with a great warranty to back it up.
- Calico Coatings is from the heart of race country in North Carolina. They are Kooks preferred coater, and offer not just header coatings, but a wide range of engine and industrial coatings.
- Jet Hot Coatings will still be offered for those who demand the name, however it will be at the new, higher price.

What Sets Kooks Apart?
Kooks is known for building the best high end consumer headers in the world. This header is constructed with the below high end features!
Tig welded with all 304 (aircraft grade) mandrel bent stainless steel construction
Integrated venturi merge spike for better savaging and less collector turbulence
Primaries blended into the flange for better flow
Leak Proof Ball Flange collector for trouble free ownership.
Each primary tube is one continuous piece of tubing. Some competitors weld several pieces of tubing to create one primary, which is a weaker design.
Quite simply...there is not a better header on the market!
