1.Getting more air into your engine and more exhaust out is the key to a performance motor. That's where exhaust headers is significant as the first revenue of an exhaust system. Exhaust performance headers manipulate the air flow with the performance-robbing exhaust manifold that came with your car.
2.Headers provide each cylinder with its own mini exhaust pipe, which means exhaust headers prevent interference among cylinders; thus, the back pressure that occurs in common exhaust manifolds. When cylinders don't have to fight with each other to expel their exhaust, they can put more power through the wheels, pushing the vehicle. Combining with a high performance cold air intake, and a cat-back exhaust system, a header system removes all restrictions of your engine, then, it is able to perform at its full potential.

Customer Reviews
Thank yall so much for your service
Everything is good, except for the middle spark plug on the driver side. The middle pipe needs to be re-routed b/c the wire literally rubs on the header causing the spark plug wire to burn up. Unless you can find a 45/90 degree spark plug wire, you have to either wrap the hell out of the wire with heat wrap or the header itself. Otherwise, good part. Easy bolt on and install
Left a previous review before installing based off the product I received but after install I am very happy with it. They slide in and mount easily, installation was easy aswell and sound great with a Truck Norris cam. Only thing, buy your own manifold bolts because the ones provided do not look trustworthy for long term use and appear they will break or strip later on but I have no regrets for the price at all.
The fit was just right, and it gives a nice boost to performance.
First off they left out the gasket you need for the 2-1, the header bolts feel and look extremely cheap, and my spark plug wires are touching the headers. If you can I’d recommend spending a little more money on a better set
