Flowmaster has been designing and developing exhaust systems since 1983. All Flowmaster products are researched and manufacture right here in the U.S. Flowmaster started in California with the racing scene. Their team was dissatisfied with exhaust standards and strove to find a solution to quieting the race cars without sacrificing performance. They succeeded and become a leader in aftermarket exhaust systems for a huge variety of vehicles.
Flowmaster’s R & D team works tirelessly to produce unique solutions for individual vehicles. When Flowmaster says a particular system is for a Wrangler, the system is developed into a direct bolt on design, utilizing the shape of the body for a peerless fit. Each system is dyno tested and proven before being sent out into the consumer market. The product development doesn’t stop there. Flowmaster is always willing to hear feedback from their customers, so they can continue to improve.
We at Extreme Terrain carry Flowmaster’s axle-back and cat-back Force II set ups as well as the American Thunder cat back system. Both systems are made from 16 gauge aluminized, mandrel bent tubing. The Force II systems feature Flowmaster’s 60 series Delta Flow muffler for a stock to mild sound. The American Thunder systems feature Flowmaster’s 50 series Super muffler for a moderate aggressive tone. Flowmaster promises improved throttle response, power, and gas mileage with both systems.
