About Gibson Exhaust-

It was because of our motorhome that my wife, Julie, and I started this business in 1990. Like you, we needed POWER and TORQUE…and a lot more of it! But when we looked for the right exhaust systems for our needs, it was more like spinning a roulette wheel and hoping. After much study, we hired the best engineers and technicians and began producing prototype models.

We set our goals high: a cost-effective system that delivers more performance for the dollar than any other system. One that not only increased horsepower and fuel economy, it expanded the power bands, the engine ran cooler, engine life was not compromised, and the entire system (including installation) was hassle-free.

In the early 90’s, when performance exhaust systems became popular for sport trucks and 4x4’s, friends asked, couldn’t they get the power and torque they wanted with lower level of noise inside the cab? With our complete testing and manufacturing already in place for the RV market, phase two of GIBSON began. Today, customers and industry experts agree, GIBSON is the most cost-effective performance exhaust system. We’re emission legal in all 50 states and installation does not affect factory warranty. Exacting specifications assure the installer and purchaser that all systems fit properly and yield programmed benefits.
