Header Kits

Want to replace your exhaust manifold without having to piece together pipes and connections yourself? A header kit combines headers and the pipe that connects them to the rest of the exhaust in one package. This category is for you if you want parts that are designed to work together.

What does a header kit include?

The kits typically consist of headers – manifolds with separate tubes for each cylinder – plus a connecting pipe to the rest of the exhaust. In this category you will find, for example, kits from Kooks Headers with a Y-pipe or X-pipe with catalytic converter, including a kit for the Chevrolet Silverado 1500 6.2L and one for the Chevrolet Corvette Z06 ZR1. If you are only looking for the manifolds themselves, you will find them under exhaust headers.

How to choose the right kit

Start with your car model, model year and engine, as the kits are developed for specific vehicles. Then look at:

• Tube diameter: The dimensions in the product name, e.g. 1-7/8 x 3, typically indicate the primary tubes and the collector in inches. The right size depends on the engine, other modifications and power goals – bigger tubes are not automatically better.
• Y-pipe or X-pipe: The choice depends on the car's original exhaust and how the rest of the system is built.
• Catalytic converter: Kits with a catalytic converter can make it easier to meet emission requirements, but road-legal approval depends on the product and the car and must be checked for the specific part number.

Installation and maintenance

Installation typically requires a lift, new gaskets and often relocating the oxygen sensors. Retighten the bolts after the first heat cycles, as gaskets can settle. Depending on the project, a modified exhaust may require adjustment of the engine management. If you want to compare with other solutions, you can see all headers.

Frequently asked questions

What do dimensions like 1-7/8 x 3 in the product name mean?

The first dimension typically indicates the diameter of the primary tubes in inches and the second that of the collector. Choose the size based on the engine, other modifications and power goals rather than simply going for the biggest tubes.

Can a header kit with catalytic converter pass inspection?

It depends on the specific product and the car. Check the documentation and approval for that exact part number before installing, as the rules for modified exhausts must be met for the individual car.

Why does the exhaust tick after installation?

A ticking sound, especially with a cold engine, is often caused by a leaking gasket or bolts that have settled after the first heat cycles. Retighten according to the manufacturer's instructions, and check the gasket surfaces if the sound persists.
