    Guides & Articles
    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.

    Just What I Wanted!
    2007 Chevy Avalanche | Posted by Jordan | (Dewitt, IA)

    I had this exhaust system installed at an exhaust shop for under $150. The mechanic that worked on it had nothing but good things to say about it and that the kit came with everything he needed. He did say that a brake line had to be slightly moved, but that it was no big deal at all. As far as the sound goes, the video on this website does do it justice...but just like in the video, it could be just a little louder (it is definitely loud enough and cool sounding enough that it will turn some heads, but for sure no one will be plugging their ears). Overall, great price, great product, and great sound....just what I wanted! (Exhaust was installed on a 2008 Chevy Avalanche z71 LTZ).
