Replacing the OEM catback on your car is one of the first modifications we recommend to any new car enthusiast. Replacing the OEM catback with an aftermarket exhaust system is a great way to increase horsepower, style, and the sound of your car.

Many people often ask, how did the brand BBK come to be and what does BBK stand for. It's actually the initials of company founder and current CEO Brian Murphy, his best friend from high school Barry Morrison and Brian's younger brother Ken Murphy. Growing up in a small town in the northeast during the 1970's & 80's, Brian would read car magazines like Hot Rod & Car Craft and dream about Southern California and the performance industry as it was the birth place of the car culture and home of many companies such as Edelbrock & Hot Rod Magazine. Upon graduating high school in 1987, Brian convinced Barry to join him in driving out west to Southern California to start a new life and attend college. A few months later after seeing how popular the new breed of electronic fuel injected pony cars like the Mustang and Camaro had become, Brian had the idea of starting a company that would sell performance bolt ons for these new platforms. Back in 1988 the leading aftermarket companies such as Summit Racing were focused on performance for the old school carbureted muscle cars and really didn't understand Detroit's latest fuel injected platforms.
