Description
Get an Incredible Boost in Power. If you want to give your Chevrolet Silverado 1500’s power a significant performance boost, installing these Flowtech 1-5/8-Inch Shorty Headers with Ceramic coating is what you need. These headers are less restrictive than your stock units, so they’re capable of hitting higher exhaust velocities. This in turn gives you an increase in horsepower and torque numbers, unleashing your vehicle’s high-performance capabilities as a result.
Brand New Exhaust Sound. Installing these Shorty headers will give your Chevy Silverado 1500 a more powerful personality. Thanks to their mandrel-bent construction, they’re able to generate a more aggressive exhaust sound that can make the roads and trails shake.
Uses Factory Cats. Designed to use your vehicle’s existing catalytic converter, these headers seamlessly work with your truck’s current setup. This also makes them easier to install than other headers.
Built to Be Tough. Flowmaster’s shorty headers can handle the abuse brought by the harshest driving conditions. Boasting a 16-gauge mild steel tubular build, the headers won’t be so easily damaged by the stress of your high-performance drives. Additionally, they come with 3/8-inch TIG-welded machined header flanges to prevent them from leaking exhaust.
No Tuning Needed. These headers are made to complement your truck’s current setup. As a result, you won’t need to tune your vehicle after installing the headers. However, it’s recommended to test drive the upgrade and check for any new noises. Also, you have to re-tighten the bolts after several days of driving.
CARB-Compliant Upgrades. These headers are legal for sale and use in states that adopt the CARB emission standards. Its CARB EO number is D-115-20.
Application. These FLowtech 1-5/6-Inch Shorty Headers with Ceramic coating fit all 2002-2013 4.8L and 5.3L Chevrolet Silverado 1500 models
