Kooks 1 7/8″ Long Tube Headers – 2014-2018 Chevy Silverado, Sierra 1500 & GM Fullsize SUV V8 (5.3L & 6.2L) – 28602401

Looking for the best performing, finest American made exhaust header? Look no further than Kooks Custom Headers!

These Long Tube headers feature all 304 Stainless Steel, mandrel bent, TIG welded construction, a 3″ merge collector with merge spikes and a leak proof ball & socket connection. They include O2 bungs for all factory O2 sensors. They also include all bolts, gaskets, and hardware to install. These headers also come with Kooks limited lifetime warranty.

These headers will require a Kooks Y-pipe for a bolt on installation to your factory or aftermarket catback (select in drop downs).

The Y-pipes have the following options-

Off Road – Deletes your catalytic converters.
High Flow Race Cats – The same catalytic converters the other manufacturer uses. Very high flow, requires a tune to not have check engine lights.
Ultra High Performance Green Cats – The best catalytic converter you can buy. Rated for 900HP and flows better than standard race cats. In many cases they don’t throw check engine lights also.

What size header should you buy?

1 3/4″ for stock or otherwise bolt on cars
1 7/8″ for stock, bolt on, or mildly modded cars to about 500rwhp. Basically on a stock car they perform the same as 1 3/4″, but give you room to grow.

What is Header Coating?

We offer a number of coating options at a great price. Header coating makes your car run cooler and perform more consistently. It is not 100% necessary on a stainless header like this, but is great for someone who wants an extra edge at the track and lower cabin heat. Coating will add 2-4 weeks to normal order times. If this a concern, please contact us prior to ordering.
