# Title: 304ss Valved Catback Exhaust for Porsche 911 997.1 997.2 Carrera 4S


## Description: Upgrade your Porsche 997 Carrera / Carrera S with the STRATEC Valved Sport Exhaust System in T304 Stainless Steel, engineered to deliver a sharp, high-revving motorsport-inspired sound with durability for long-term street and performance use. Featuring equal-length performance headers, a free-flow X-pipe, and valved side mufflers, this complete exhaust system transforms the 997’s tone into a clean, aggressive, F1-inspired sound profile. With valves open, it produces an intense, track-focused exhaust note. With valves closed, volume is reduced significantly for a more refined and comfortable daily driving experience. This is a full-system upgrade — not an axle-back — ensuring optimized flow, tone balance, performance response, and reliability. What’s Included Equal-length stainless steel performance headers Free-flow stainless steel X-pipe Valved side mufflers for adjustable sound Quad exhaust tips Complete vacuum valve control hardware Features T304 Stainless Steel construction for corrosion resistance and longevity Vacuum-controlled exhaust valves with factory-style operation Approx. 21.8 lb weight savings vs factory exhaust Mandrel-bent piping for optimized exhaust flow Precision TIG-welded for strength and durability 100% bolt-on and reversible — return to stock anytime Vehicle Fitment 2005–2008 Porsche 997.1 Carrera / Carrera S 2009–2012 Porsche 997.2 Carrera / Carrera S Convertible models supported
