I like flowmaster pretty good exhaust system not to loud perfect sound but it didnt come with the right clamps and did not come with flange hardware i think if your paying 500 bucks for exhaust they should atleast enclude the flange nuts other than that i think its a great exhaust

GMC Exhaust System Articles

The GMC exhaust system is designed provide a smooth and efficient means for eliminating and processing the waste products produced by the engine as it runs. The engine in your vehicle uses a cyclical process of combustion to produce the power used to propel your vehicle, creating a number of chemicals as byproducts of this process, as well as a great deal of noise. The GMC exhaust system carries these waste products away from the engine and directs them through a number of exhaust components designed to remove a large portion of the dangerous chemicals they contain, and quiet the noise of the engine, reducing the levels of the air and noise pollution emitted from the tailpipe as the vehicle operates. The process begins with the collection of exhaust fumes and sound waves that carry engine noise in the GMC exhaust manifold as they are expelled from the exhaust valves. These waste products are directed away from the engine in a smooth flow to continue along the GMC exhaust system to the catalytic converter. The catalytic converter traps some chemical molecules, and burns others to reduce the amount in the exhaust gasses, before sending them on to the muffler. The muffler is in charge of reducing noise pollution, using several sound reducing techniques to quiet the sound wave produced by the engine. As the exhaust gasses leave the muffler, cleaner and quieter, they are then allowed to exit the GMC exhaust system through the tailpipe to be released into the air. Our online catalog caries a variety of quality GMC exhaust parts, all at great low prices. Our secure site makes ordering safe and easy, or placing your GMC exhaust parts order is just as convenient on our toll-free phone line, with expert customer service for your assistance.

How to Choose Your GMC Exhaust System

The exhaust system isn't designed to simply carry the exhaust gases from the engine and out. Every component comprising it can have a huge effect on the engine performance, fuel economy, as well as the environment. Installing anything that doesn't suit the specifications of your GMC exhaust system can be detrimental, so you need to make careful choices. But how would you know if you are getting one that can bring a level of improvement to the performance of your GMC? We will give you a hand with that.

Focus on your goal

Don't get lost with the idea that you can have just any exhaust system you see in stores and actually get what you expect from it.

  1. Gain extra power. The GMC exhaust system does not necessarily create extra power for the vehicle, but it simply aids the engine in performing with more efficiency. Headers or exhaust manifolds mainly work on this aspect in a sense that the ability of the system to quickly rid of the engine's waste products lies in their design. If the design is more restrictive, the engine cannot produce power in the optimal way because some of the exhaust gases will still be in the combustion chamber, depriving it of its needed oxygen. In fact, such a design will cause backpressure. Less restrictive mandrel-bent headers for single exhaust system and crossover pipes for dual exhaust system can help your engine get that extra power.

  1. Keep the noise low. While many car enthusiasts are thrilled with the aggressive sounds produced by performance mufflers, some want silence while travelling. Good thing, GMC exhaust system can have the kind of muffler that really makes significant reduction of exhaust noise. Most aftermarket mufflers are designed in such a way that their baffles, chambers, perforated tubes, and sound deadening materials refine the noise or even produce different tones. However, those components are the very ones robbing the engine of some power. Manufacturers also create mufflers that don't cause too much backpressure, though. Ask the dealer about the level of noise reduction that your chosen muffler can make.

  1. Stay within emissions regulation. Aside from saving yourself from the hassles of having to deal with emissions regulation violation, you are also able to help push a noble goal of saving the nature from the detrimental effects of noxious vehicle emissions. If you haven't upgraded with header-back system or exhaust manifold so as to achieve a performance exhaust system, this issue should not worry you. But if you already did, a quality catalytic converter will be of great help to you on this matter.

  1. Bring out a new look. The tailpipe or the tip of the exhaust system is the one basically affecting the aesthetic aspect of your GMC. And for improved appearance or to achieve a custom look, make sure to get the one that complements the overall look of your vehicle. Carefully choose from various shapes and finishes of exhaust tips available for different GMC units.
