The Hummer H3’s overbearing presence is as attractive as it is compelling. Make your H3 even more domineering with a brand new custom exhaust system from CARiD. Built specifically for the H3 engine, our exhaust systems will harness the power of your engine for additional horsepower and torque. Pick a fitting exhaust from the range of Corsa, Borla, Flowmaster, MagnaFlow, Gibson and CGS cat back exhaust systems on our shelves. On average, any of these will give you between 5-12% more power and about the same amount of torque. Pairing up an exhaust system with a performance header will boost the engine’s horsepower by 15hp – 30hp. Altogether, your H3 will have greater towing power and will demonstrate a force that was previously absent whenever you shift gears. Custom exhaust systems for the Hummer H3 are extremely effective in boosting power and performance because they are built to do so. This is unlike the stock exhaust system which is only built to block noise from making its way into the environment, and has no capacity to engage the engine’s power.
Along with greater power and torque, your H3 throttle response will be enhanced such that you get instant power every time you press the gas. More exciting is how the engine dispenses more power even when driving at low rpm ranges, adding an impressive amount of thrill to the whole driving experience. Fuel consumption goes down by a considerable margin now that the engine is more efficient at burning fuel. Expect an average of 1-2mpg more when you fit your H3 with a custom exhaust system. And of course you will make huge savings over the long term with a Hummer H3 performance exhaust system because it does not wear out fast or lose its excellent performance edge as happens with cheap OEM exhaust versions.
Unbridled power and outrageous sound - that's what accompanies each exhaust system we store for you on our digital shelves. Manufactured from the premium materials using the latest technologies, they all are ready to complete the image of your vehicle and give you instant horsepower and torque gains. After an exhaust system is installed, your vehicle will roar like a lion and run like a cheetah. Have doubts?

"I found the product easy to install, the only improvement that I could suggest is making all lengths of exhaust pipe so that they prefitt. I had to go to an exhaust shop to widen the pipe so that it would fit inside each other. Then cut slots so that it would tighten. Product sounds great and looks good. "

"I replaced my Magnflow exhaust system with a Flowmaster. The Magnfow after several years became very loud. I contacted Magnflow 5 months ago for a free warranty replacement and they gave me the run around. So after repeated calls with no success I bought a Flowmaster. This system is great and my wife now rides in my Hummer again."

"I love Magnaflow Cat-Back System. The Instruction I received were very easy to follow. Once installed, the new exhaust looks stock because the Hummer H3 comes custom with two cut outs that are fit for the new Dual system. Great sound too! I Love It!!!"
