Pit Stop USA is The Online Motorsports Superstore! Boyce Industries, Inc. is a performance-oriented company that for over 40 years has been directly involved in motorsports from racecar chassis design and fabrication to the manufacture of competition proven racing products. In the mid 80's Boyce developed a complete oval exhaust system for competition use by NASCAR teams. This was followed by oval track muffler development and in 1994 the boom tube exhaust outlets. Since that time Boyce has consistently supplied racing teams with component parts and one-piece oval exhaust systems. All Boyce oval exhaust products are produced in house. A modern custom design tube rolling mill and aerospace bending machines supported by an in house tooling department allows Boyce to totally control product development and production.
