We Will Price Match on These Headers!


Effective 04/01/15 Kooks has discontinued the 1 3/4 version of the GTO header. This is due to low demand, and the very small difference in performance between a 1 3/4 headers and 1 7/8 headers on a stock GTO. The 1 7/8 version will of course better handle additional modifications.


Note: These headers fit the 2004-2006 Pontiac GTO. The headers themselves are the same for all model years, the only difference is the mid pipes.


These 304 stainless steel long tube headers are for the 2004-2006 Pontiac GTO. Kooks builds all of their products to the highest standard, and these are possibly the best headers you can buy for your GTO. They feature 1 7/8 primaries, and 3 collectors with O2 Bugs welded in. With a proper tune at a dyno shop, or SLPs Diablosport Tuner, these headers are good for 20-35HP depending on the vehicle.


To connect your new header system to your factory/aftermarket catback exhaust, you can also select either Kooks 3 Off Road Mid-Pipes, or their 3 Catted Mid-Pipes that include metallic catalytic converters. Both are made of stainless steel and engineered to the same high standard as Kooks other products! Includes O2 Extenders, along with all bolts and gaskets needed for installation.


SPECIAL- For a limited time, add Kooks 3 Street Screamer Catback for only $999.95 SHIPPED (Save $100) when you buy both Kooks GTO Headers and Mid Pipes! Click HERE for me details on this exhaust!

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!



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.
