Exhaust Header VS Manifold, which is the better choice?

The structural differences between exhaust headers and manifolds are the material and size. From the material, exhaust headers are made of lighter, thinner steel, while exhaust manifolds are made of thick iron. Exhaust headers are also longer than exhaust manifolds. When in use, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure. Therefore, exhaust headers are a BETTER choice than an exhaust manifold.

Replacing or upgrading your exhaust header is necessary for both engine performance and sound. Whether on or off the track, exhaust headers provide more horsepower and improved exhaust sound. 

What is the purpose of the exhaust header?

Boost Horsepower and torque, and Save on Gas with Headers and Exhaust System Modifications!"

Replacing a vehicle’s headers and exhaust is a way to add horsepower and torque, and it will also increase your vehicle’s volume. Want a car that sounds like an American muscle car should? This header will help your vehicle achieve that and it can add up to 8-20 horsepower.

Install an exhaust system means about a 0.5 mpg gas mileage improvement. While that might not sound like much, consider this: If gas costs $3 a gallon, and you drive this truck 15,000 miles a year, you’re saving yourself about $85 a year on gas. In five years, you’ll have saved nearly enough money to pay for a complete cat-back exhaust system.

The welds will hold

On a 2011 there is a fitment issue around the steering column and brake lines but you can just heat it up and beat it out, AND THE WELDS HELD 👍

Passenger side fit good. Drivers side is super tight to the block so it took forever to get it tight. I also think its not angled quite right as its leaking at the collector/y pipe already.
3stars cause price. And the passenger side doesnt leak.

Decent quality, good price

I put the headers on...decent quality and fitment but struggled to put middle two bottom bolts on driver side header due to pipes and motor mount, it could be easier to install but not the end of the world

Thank you for your review, we will continue to improve the product!
