The piping is also mandrel bent in order to retain the same piping diameter at the bends thus optimizing exhaust flow characteristings. Straight through muffler design gives better flow for increased power and allows for a lighter weight system. Compact muffler canisters offer optimal ground clearance for lowered vehicles. Furthermore, the dual-wall angle cut tips have a large inner diameter for modern aesthetics and increased exit flow. The Medallion Touring-S exhaust system is fully hand TIG welded and utilizes laser cut flanges that are stronger for more durable connections. Tested under 93db sound levels under load, the Medallion Touring-S exhaust system gives a clean deep tone that is pleasant at all RPM ranges while maintaining exhaust efficiency.
