Agency Power Headers

Performance Exhaust Headers

Eliminating the manufacturers exhaust manifold and adding a set of performance exhaust headers is the best way to reduce power robbing back pressure from your cars engine. Normal exhaust manifolds cause back-pressure when your engine runs. Manifolds use one chamber for 4 firing cylinders. An exhaust header is built to give each cylinder its own exhaust tube to vent through. This design eliminates the back-pressure and gives your cars engine a great boost in power. Vivid Racing carries exhaust headers for almost all vehicles and from many of the top high performance manufactures in the racing industry.

Now that we have cleared the airway for your engine to breath out, let's take a look at your engines ability to breath in. Vivid Racing carries Cold Air Intakes, Short Ram Intakes and all the accessories to boot. So take a look at our Intakes category and if you have any questions give us a call.
