    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.

    2008 Ford Expedition | Posted by Ira | (Oceanside, CA)

    Gotta admit that I was rather surprised by this kit. I've worked on Mustangs and various other cars for a while now and the common trend with exhaust no matter the cost has always been figment and alignment issues. However this kit was super easy to install, fit and finish is spot on, and the quality was really nice. Didn't expect that for the price. Let me tell you though, the video for this product does it no justice. This kit sounds amazing on my 2008 Expedition and I couldn't be any happier!
