Whether the 2014-2018 headers you’re seeking for your GMC Sierra truck are shorty headers for high-range performance or long-tube headers to boost low to mid range power, AmericanTrucks has the component you want. The 5.3L V8 engine headers include stainless steel designs that are highly corrosion and rust resistant. You can choose between a chrome finish and a ceramic finish – the first providing a gleaming, mirror-like appearance, the second offering a softer, velvety satin look. These headers, as well as the 6.2L V8 headers also available, are sold both separately and with a Y-pipe (mid pipe) with a factory connect. These Y-pipe equipped headers can be either off-road only variants with a deleted catalytic converter, or a catted version that’s street legal (though still providing improved power and sound). AmericanTrucks’ selection is all about giving you as many options as possible so you can find the header perfectly suited to the upgrade you’ve got in mind.
