The Touring Edition is a full 3" straight-through stainless steel catback system that optimizes power output while eliminating drone noise across the entire RPM range. It features a meticulously designed H-pipe and AWE's patented drone-canceling technology, 180 Technology, delivering deep, rich exhaust notes that command attention. The Touring Edition offers a 12lb weight reduction compared to stock. AWE 180 Technology ensures perfect tone: exhaust gases entering an AWE 180 Technology equipped resonator pass through strategically placed ports into reflection chambers. Sound waves bounce off these chamber walls, and by controlling port and chamber size and location, problematic frequencies are canceled out by reflected sound waves rejoin the main exhaust flow.
