Fabspeed's 991 Turbo Valvetronic Supersport X-Pipe Exhaust System replaces the restrictive OEM rear mufflers and catalytic converters for a deeper, throatier exhaust note along with improved power and throttle response. With valves open, unleash a bold roar from your 991 Turbo.

• Fits all 991 Twin Turbo / Twin Turbo S vehicles (2014+)
• Available in a Race (Cat-Bypass) or Street (Sport Cat) configuration depending on your vehicle application
• Fully controllable valved exhaust system includes a quad-resonated center x-pipe section which mitigates exhaust volume while the valves are closed. When the valves are opened, the exhaust bypasses the X-pipe for an aggressive tone. Two unique sounds; one exhaust!
• Dramatic improvement in sports car sound and power throughout the RPM range
• Includes Deluxe Quad Style Tips in your choice of finish
• Constructed from high-quality 14-16ga C.N.C. mandrel-bent T304L stainless steel for optimum flow and maximum durability
• Sport Catalytic Converters optimized for maximum performance with NO check engine light, guaranteed
• Simple bolt-on installation; no cutting or welding required
• Option but available valved pipes with NO catalytic converters- your car will sound like a 935 and 962C.
• All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
