    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.

    2006 Chevy Silverado | Posted by John | (Vacaville, CA)

    I received my order in minimal time 2 days. Unfortunately my son decide he no longer needed this part, but that's when the success story starts. I received my return authorization in 2 days with postage paid & apology it didn't work out. My account was paid back without the typical restocking fee. Wow great company to work with. I will not only work with theses guys again I am telling my friends to give them a shot Good job! John, Vacaville, California.
