After WWII, Jerry Paolone left his home in Italy and moved to the United States. As an extension of Car Sound Exhaust, Magnaflow believes in top quality, maximum power, and the best exhaust sound for your vehicle. Magnaflow dyno-tests every product they make, and their ISO-9001 manufacturing certification assures every part is made to the highest standard. When faced with the question of moving manufacturing overseas in the early 2000’s, Jerry objected, remodeled his facilities, and continued offering top-level benefits to each of his employees. Their headquarters in CA is state-of-the-art, and Magnaflow is constantly innovating.
