Why should I get performance exhaust headers?
Why should you install a set of performance exhaust headers? We at AutoAnything think Tim "The Tool Man" Taylor put it best when he grunted, "More Power!" An explosive dose of tire-turning, rubber-burning, street-screaming thrust is what's waiting for you at the end of the installation rainbow. But that's not all. When you equip your motor with some high-octane performance exhaust headers, you get:
Why do performance exhaust headers pack such a mighty punch? The answer lies in how the pipes are shaped. Each twist and turn in the tubes is formed using a mandrel bender, an advanced tool that actually inserts a rod into the pipe before it's bent. This ensures a consistent internal diameter, so there are no restrictions for gasses to stumble over. This smooth flow also increases engine scavenging, the vacuum effect that draws exhaust fumes out of your cylinders, for greater efficiency and more power.
Another way that performance exhaust headers add bite to your gas pedal is by relieving backpressure. You see, spent gases created during combustion are pushed out of the cylinder and into the exhaust manifold. In a stock manifold, all the fumes flow into a single chamber, where they run into each other and fight over room. If the manifold clogs up, then the gas runs into resistance as it leaves the cylinder and your engine wastes energy (and fuel) compensating for the blockage. With a set of performance headers, each cylinder gets its own pathway, so the gas doesn't have to compete for space. All sections of pipe then merge into a collector, which links into the rest of the exhaust system. What's more, each piece of pipe is the same length, so the exhaust fumes flow into the collector at evenly spaced intervals instead of all at once.
Put it all together, and a set of performance exhaust headers can unleash an extra 5-25 horsepower and a big spike in torque, depending on your vehicle. Combine that with a performance cat-back exhaust, and you'll have even more power at your disposal.
It's often said that a chain is only as strong as its weakest link. Likewise, your engine can't run efficiently if any of its components are tripping up the process. One of the worst roadblocks is a stock exhaust manifold. This restrictive part creates deadly backpressure, which clogs up your cylinders and kills your miles per gallon. Moreover, it adds an unnecessary amount of extra weight that keeps your fuel gauge constantly spinning in the wrong direction. There is a solution—performance exhaust headers.
Engineered for efficiency as well as power, performance exhaust headers streamline the flow of spent gases from your engine. Plus, their steel construction shaves a few pounds off your vehicle's weight, lifting a load off your motor's shoulders. Taken together, these improvements will have your motor running more efficiently, so you can pass the pump.

Your engine's natural tone is menacing. Unfortunately, stock exhaust systems stifle this inherent roar, subduing it to an almost imperceptible peep. Performance exhaust headers help break the silence. Since the piping is not nearly as thick as factory-installed manifolds, there is less insulation to dampen out the guttural growl. When you bolt on a matching cat-back exhaust, you can further tune your engine to a distinct rumble.
Ever try jogging a mile while holding a 50-pound sack of cement? Unless you're training for a strongman competition, you wouldn't dream of subjecting yourself to that kind of needless toil. Extra weight makes us work harder to get the same job done, and the same is true for our vehicles. Unfortunately, most vehicles come from the factory bloated, and those excess pounds force engines to work double quick. Not only does this slow you down, but it also wastes gas.
Much of the surplus mass on your vehicle comes from clunky, cast iron parts, and one of the worst culprits is your stock exhaust manifold. These massive hunks of metal are incredibly dense and add unnecessary weight. Performance exhaust headers strip away the fat from your engine compartment. Crafted from lean steel instead of bulky iron, they deliver durability without the flab.
It's inevitable that temperatures will rise under your hood, but an extreme buildup of heat can harm performance. Your motor thrives on oxygen, especially colder oxygen. That's because chilled air is denser, so it burns more efficiently. As the mercury rises in your engine compartment, the air flowing into your engine heats up, becomes less condensed, and does not combust as energetically.
While it's not practical to run an air conditioner in your engine compartment, you can cool things down with a set of performance exhaust headers. Their greater surface space and thinner walls allows heat to dissipate easily.
Pop open the hood of most vehicles, and there's usually nothing exciting to feast our eyes on. More often than not, it's just a bland mix of oily plastic, rusty metal, and tangled wires. This is not the case for an engine compartment that's been dressed up with an aggressive pair of exhaust headers. With a set of these radical manifolds mounted on your motor, you'll look more like a dragster than a commuter. Available in numerous finishes, you can get everything from the attention-grabbing glint of chrome to the track-ready look of ceramic.
There is a ritual that nearly all of us have to perform every year or so before we can re-register our vehicles: the smog certification. Besides measuring the levels of noxious fumes rolling out of our tailpipes, the smog technician also performs a visual inspection. He's checking for aftermarket parts that might be bypassing or altering pollution controls, like oxygen sensors or catalytic converters. As long as the performance accessories do not alter these smog-controlling systems, then you're in the clear.
Most of the performance exhaust headers at AutoAnything are 50-state street legal. In other words, they don't interfere with your onboard pollution controls and can pass a smog test in any state. How can you be sure that your performance headers are indeed 50-state street legal? The easiest way to know is to check our product descriptions. We'll tell you whether they are for street use or for off-road use.
Another way to know if your exhaust headers are 50-state street legal is when they come with a CARB EO number. CARB is an acronym for California Air Resource Board, a governor-appointed group that sets the limits on how much greenhouse gas your vehicle can emit. They are also in charge of testing and determining whether or not an aftermarket product meets their notoriously stringent requirements. For parts that pass, they get a CARB EO number, which is the board's seal of approval. For slick street use, slap on a set of Borla, Bassani or JBA headers.
We also carry performance exhaust headers which are designed for "off-road" use. These performance headers are specially made for smog-exempt vehicles, like older cars and dedicated racecars. If you are unsure about your vehicle's status, check with your local DMV. Trick out your track star or off-roading mayhem-mobile with the power-packed punch from Dynatech, Pacesetter and Edelbrock headers.
