In 1983, Thermal started as a small muffler shop in Canoga Park, California. As enthusiast demand for American-made exhaust systems grew, so did the scope of our business and the size of our team. Starting with classic cars and then transitioning to import tuner cars in the early 90s, Thermal transitioned from a small shop to a high-quality design and manufacturing business. Today we continue that tradition of catering to discerning enthusiasts while we increase our product offerings to a wide range of vehicles.
