Quality. As a market leader, we proudly manufacture all of our products in the USA using premium components and the latest technology. Our products range from direct-fit converters and cat-back systems to universal mufflers and builder’s kits for fabricating your own custom system. As an ISO-9001 certified company we believe in our product’s ability to perform and back it up with a lifetime warranty. Power. In our 31 years of experience we’ve learned that automotive enthusiasts always want more. Our 30,000 square-foot R&D tech center is home to two in-ground dynamometers, a flow bench, and sound testing to ensure that every new part passes our quality and performance standards before being approved for manufacturing. If it doesn’t produce power, we don’t make it. Sound. We want you to have the best sound possible. With this in mind, we’ve designed our mufflers to have a free flowing, straight through design with a perforated stainless steel core, mesh wrap and acoustical fiber fill to deliver that smooth, deep tone. Our mufflers are packed tight with the acoustic material to ensure long life and no sound degradation.
