35 years ago, Flowmaster® mufflers were conceived as a solution to a growing problem with sound issues at race tracks in California and beyond. In his successful effort to quiet race cars without reducing performance, our founder refused to accept the status quo of the day and instead pushed exhaust technology beyond common thinking. This led to many firsts in automotive exhaust science, as well as many patents protecting the various technologies used in Flowmaster® products. With those developments, Flowmaster® ushered in a revolution in automotive performance exhaust. For years, Flowmaster® has been committed to delivering the best automotive exhaust products to the market and being "The Exhaust Technology Company." Our mission has always been to bring you the highest quality exhaust products through innovation, advance manufacturing experience and dedication to customer service and satisfaction. Now, we're taking that mission statement to the next level by offering exciting new product categories to enhance our exhaust offerings. We now offer Delta Boost tuners for turbo-charged applications and Delta Force® performance air intake systems for numerous late model applications. These new offerings have been designed and tuned to work in combination with our tested and proven exhaust products to maximize your vehicle's performance. Now you can pick up an entire performance package in one place and from a company with a name you know you can trust, Flowmaster. Like today's cars, trucks, SUV's, Jeeps and UTV's we too have evolved. Our new mission is to be "The Performance Technology Company." Our R&D department is headed by long time Flowmaster® exhaust expert and V.P. of R&D, Lee Thompson. Lee and his team work tirelessly to bring new exhaust systems, mufflers and exhaust products that are specially fitted and tested for most popular brands and models to market. Our dedicated R&D team continuously monitors the performance of our exhaust products.
