We Will Price Match on These Headers!- Call us @ 443-730-9428 with Questions!
These 304 stainless steel tube headers are for the 1999+ GM Full size Trucks and SUV's. (Silverado, Sierra, Tahoe, Yukon, Escalade, Avalanche). Kooks builds all of their products to the highest standard, and these are possibly the best headers you can buy for your Truck. They feature 1 7/8" primaries, and 3" collectors with O2 Bugs welded in. With a proper tune, these headers are good for 20-40HP depending on the vehicle.
These headers work for the 4.8, 5.3L, 6.0L and 6.2L engines. All headers will require a Kooks Y-pipe to connect to your factory or aftermarket exhaust. While the headers themselves work for all three motors, but the Y-pipes are very application specific, please take care to order the correct one. If you have questions, feel free to call us @ 443-730-9428. All Y-pipes are offered with either high flow cats, or cat delete (off road). Both are made of stainless steel and engineered to the same high standard as Kooks other products!
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, Jet Hot, our main coater who we have had a great relationship with 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, which 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.
