Open Pipe Performance Without The Sound

Flowmaster's Pro Series Laminar Flow Mufflers work on all applications ranging from sprints and midgets, vintage racing, rock crawlers, and diesel sled pullers. The Pro Series Laminar mufflers consistently deliver performance that is equal to or surpasses open pipe systems, while dramatically reducing sound levels across the RPM range. A key feature is its Cool Shell technology which minimizes the outside case temperature for mounting in and around body panels.
