    Regardless of whether you're shopping for a simple replacement muffler that delivers original equipment (OE) sound and performance or an upgraded muffler which provides a deeper growl with increased power through freer exhaust flow, you'll see choices between "direct fit" mufflers and "universal" mufflers. In this article, we'll help you understand the differences...
    It has been a battle of the ages to make exhaust sound like it should. Having less bends or turns will not only improve the sound but also performance. A custom exhaust is always an option for the race inspired and spirited weekend warriors. Our manufactures offer everything needed to build a custom exhaust to your preference.
    Headers are installed because the stock exhaust manifolds usually flow poorly. An exhaust header has individual tubes for each exhaust port, allowing each exhaust pulse to flow unobstructed from the cylinder head. The tubes on headers are usually larger in diameter than the runners on an exhaust manifold and the tubes are mandrel bent for gradual radius bends.

    Gibson® - Dual Sport Exhaust; 6.0L Models
    2006 Hummer H2 | Posted by James | (Schertz, TX)

    Installed the Gibson stainless steel dual exhaust on my 2006 Hummer in the driveway. Install was easy and the end result, sounds great, it added some power to the 6.0 V8, and looks good too. From CARiD, to the Gibson factory support the decision was easy. The lifetime warranty for the stainless steel is a bonus as well.
