Presenting the Best Sounding Exhausts on the Planet for the C8 Corvette At the intersection of sophistication and aggression lies the Touring Edition Exhaust. A dual 3 T304L stainless steel cat - back configuration, the AWE Touring Edition Exhaust is the perfect dose of steel for drivers looking for straight - pipe performance without sacrificing perfect daily drivability a deep, sophisticated, exotic exhaust note with zero drone at highway speeds - - and V4 mode Thanks to the asymmetric design, the number of necessary bends is minimized, thus removing the unwanted restriction in flow while facilitating impressive gains across the entire powerband. Paired with robust internally lined stainless steel flex sections upstream, engine movement is significantly isolated, enabling life - long durability for peace of mind. Going the asymmetric approach also allowed us the opportunity of creating a bespoke cross - over section with entries from both the top and the bottom. Doing this we're able to achieve a rich and aggressive exhaust note out of the LT2 whether it be at idle, rev, or WOT. Beyond the unique crossover, the Touring Edition brings up the rear in proper fashion by featuring AWEs patented drone - canceling solution, 180 Technology, which targets and omits drone - prone frequencies while defeating the dreaded in - cabin tone change when switching between V4 and V8 modes. Whats this mean for you Youll be tuned into a pure, full - bodied LT2 soundtrack unlike any other without sacrificing in - cabin refinement, all while saving 31 lbs over stock. As a finishing touch, the included aluminum heat shield bolts to the bumper (via factory mounting locations) and resides neatly behind the exhaust, out of sight, with only an AWE logo showing through the rear mesh to let everyone know what team you're on. Whyd we go with an aluminum solution versus a heat blanket Heat blankets are susceptible to waterlogging and material breakdown over extended periods of time.
