Has the exhaust on your GMC vehicle been growling at you as of late? Perhaps it's just a little too throaty-sounding when you tramp on the accelerator? When your truck or sport-utility is louder than it's supposed to be, chaos ensues: pedestrians and other drivers start giving you dirty looks for busting out their eardrums, your friends and family don't want to drive with you because the sound's so unsettling, and the police in your town are likely keeping a close eye on you – or have already pulled you over and issued a noise violation warning/ticket.

This problem can easily be fixed with a part or two, but you're not enthused about spending hundreds of dollars right now. The dealer sure can be expensive, can't they? Parts outlets aren't much help either, unless you're driving that one-in-a-million vehicle that they stock affordable parts for! When you shop with us, you always get “giveaway pricing” deals on whatever exhaust components you need, be it Cat Converters, Catbacks, Tailpipes, Mufflers, Clamps, Hangers, Manifolds, Seals, or Gaskets. Make no mistake about the exhaust parts you'll find listed, we don't sell you crappy “universal-fit” units, and pass them off as OE! If the part's listed as “OE” or “Original Equipment”, you know it will install, perform, and be as durable as the dealer parts. Our vendors include only the most tested on the market like Bosal, Dorman, and DEC.

      Exhaust Kits | The Easy Way To Replace Your Exhaust System
      If your exhaust needs repair, chances are the section you noticed with a hole in it isn't the only piece on its last legs. Take a close look at that one pipe or muffler that needs replacement, and you'll find pieces on either side of it are usually pretty far gone as well. Corrosion and rust aren't selective - they attack all exhaust pieces equally.

      Exhaust Clamps, Gaskets & Hangers | Don’t Skimp on the Small Stuff!
      Exhaust system gaskets, clamps, and hanger pieces are probably some of the most overlooked parts on your entire vehicle. Since you don't see them, clean them, or maintain them, they're usually out of mind until they become degraded and fail. And degraded they are, because whenever exhaust pipes and mufflers are replaced, these old support pieces are usually always corroded beyond the point of re-using.

      Why Do Some Replacement Exhaust Manifolds Come With Catalytic Converters?
      If you're looking for a replacement exhaust manifold, you may notice that the choices available for your specific vehicle are only available with an "integrated" catalytic converter. In the same way, a search for a replacement catalytic converter may only turn up "combination" converter/manifold products.

      Direct Fit vs. Universal Mufflers
      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 between these two styles so you can make a more informed purchase.
