Bring out the maximum potential of your GMC Envoy with a custom exhaust system from CARiD. Far superior in design and concept to the stock exhaust system, Envoy custom exhaust systems are built to optimize the power within the engine, helping propel horsepower generated to a much higher level than what the car gives when using a stock exhaust system. This it does by increasing the flow of exhaust gases so that the engine is free to take in the fresh air-fuel mixture needed to generate power. To get the maximum benefits of a custom exhaust system, you need to replace the Envoy stock exhaust system with the custom exhaust built for your car specifications. And you have plenty to work with, ranging from Borla’s high performance GMC Envoy cat back exhaust systems to the MagnaFlow Street Series edition for the GMC Envoy. Any of these exhausts will give you up to 10% more power.

To get even more horsepower, you may want to consider pairing the exhaust system with a performance header or muffler from Flowmaster, Corsa, Gibson, RBP or Onki. The combination of performance and fuel economy may seem like too many benefits coming from one auto modification, but that’s precisely what you get when you fit a custom GMC Envoy exhaust system into the car. None of the unburned fuel that previously went to waste is lost, now that the engine operates smoothly. This means a higher gas mileage for you and better fuel savings. The throaty growl an Envoy custom exhaust gives makes driving this GMC SUV such a thrill. If you always wanted your car to announce your presence from half a mile away, any of the GMC Envoy custom exhaust systems from CARiD will serve that purpose.

      Engines have often been compared to air pumps, because the engine that’s most efficient in terms of economy and power is the one that can get air in and out of its cylinders the easiest. That’s why most performance modifications like conical air filters, cold air intake systems, headers, and cat-back exhaust systems are aimed at making the intake and exhaust systems less restrictive. These parts increase the flow of air into the engine and ease the flow of exhaust gas out of the engine. Among these components, headers may be the most difficult to install. In this article, we’ll discuss what headers do, their different types, and how much performance they can add to your car.
    • Performance Parts
      You may be wondering why so many aftermarket performance exhaust system manufacturers are offering dual exhaust systems connected by "H-pipe" or "X-pipe" sections. After all, aren't two separate pipes, or so-called "true duals", the best for performance? The answer is no, but to understand why we have to examine how a typical internal combustion engine works.
    • Performance Parts
      It's an age-old question that many have asked. Will an aftermarket exhaust be worth the expense? While they definitely can be, an important question to ask yourself is do you care more about the deeper sound they’re designed to produce, or the added performance gained from being less restrictive? As car enthusiasts, we’ve become accustomed to associating the sound of a car with its exhaust. After all, doesn’t everyone have a childhood memory or two of a car and the particular sound it made?
    • Performance Parts
      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.

    Exact Fit For My Envoy 2002
    Couldn't get over 40 miles per hour with out it bogging down, moved 3 bolts at the top and a couple from the back, took a bit to wiggle out backwards but it came out and the new unit slid in. Tightened the bolts and started it up, slight air leak in the gasket, probably will have to re-tighten again as it settles into position. Power is back. Runs perfect now. I would buy and do this again. J.
