The Revel Medallion Touring-S exhaust system is constructed from full SUS304 stainless steel for corrosion resistance & durability, and 1.5mm wall thickness piping for increased strength and reduced resonation. The piping is also mandrel bent in order to retain the same piping diameter at the bends thus optimizing exhaust flow characteristings for your 2015-2017 Subaru WRX / STI.
Tested under 93db sound levels under load*, the Medallion Touring-S exhaust system gives a clean & deep tone at all RPM ranges while maintaining exhaust efficiency.
*Some applications are excluded.
The Medallion Touring-S exhaust system is fully hand TIG welded and utilizes laser cut flanges that are stronger for more durable connections.
The dual-wall angle cut tips have a large inner diameter for modern aesthetics and increased exit flow.
Advantex packing material offers superior flow characteristics while offering great sound suppression. It is a highly advanced muffler packing material that greatly excels over other types such as loosely-packed fiberglass materials and composite cube types. It is heat resistant up to 1200º F and extends the functional life of the exhaust system.
Straight through muffler design gives better flow for increased power and allows for a lighter weight system with an aggressive tone. Compact muffler canisters offer optimal ground clearance for lowered vehicles.
