Fabspeed Valved Side Muffler Bypasses (992.2 Turbo)

Product Details

• Direct bolt-on replacement for the factory left and right valved side mufflers on all Porsche 992.2 911 Turbo and Turbo S models worldwide. Engineered as a precision replacement for the heavy, restrictive OEM mufflers, this system reduces weight, improves exhaust flow, and delivers the unmistakable sound expected from a high-performance Porsche.

• Save 18lbs (8.2kgs) over the OEM side mufflers while increasing performance with peak gains of +8hp and +12tq to the wheels.

• Transform the driving experience of your 992.2 Turbo with a deeper, richer, and more aggressive exhaust note while maintaining the refinement expected from a modern supercar. Fabspeed's engineering allows the twin-turbo flat-six to produce the authentic sports car sound that matches its extraordinary performance, without excessive interior drone.

• 100% emissions legal and CARB exempt, as this is a true cat-back exhaust system that does not modify or replace any factory emissions-control components. No catalytic converters or emissions equipment are altered during installation.

• Designed to integrate seamlessly with Porsche's factory exhaust management system, this system retains full OEM exhaust valve functionality and drivability. Because no emissions-related components are modified, this cat-back system is engineered to work in harmony with the factory vehicle systems and typically does not affect factory warranty coverage for unrelated components.

• Precision-manufactured from premium T304L stainless steel for exceptional corrosion resistance, strength, and long-term durability. Every Fabspeed exhaust system is designed to OEM-quality fitment standards for an accurate, bolt-on installation.

• Professional installation is recommended. Installation requires removal of the rear bumper cover, heat shields, and factory left and right side muffler assemblies.

• Every Fabspeed 992.2 Turbo Side Muffler Bypass System is equipped exclusively with genuine Helical® electric exhaust valves, manufactured in the United Kingdom and recognized throughout the automotive industry as the benchmark for premium electronic exhaust valve technology. These valves offer direct plug-and-play compatibility with the factory Porsche electronic valve control system while delivering exceptionally fast, quiet, and reliable operation.

• At Fabspeed Motorsport, we refuse to compromise on the most critical moving component in a valved exhaust system. Genuine Helical® actuators are specified because they have earned an industry-wide reputation for exceptional durability, precision, and long-term reliability under the demanding conditions of high-performance automotive applications.

• Helical® exhaust valve technology is trusted by many of the world's most prestigious performance and hypercar manufacturers, including McLaren, Ferrari, Aston Martin, Pagani, Koenigsegg, and Porsche GT models. When failure is simply not an option, leading OEM manufacturers rely on Helical's engineering expertise.

• While some aftermarket exhaust manufacturers utilize lower-cost valve assemblies, Fabspeed chooses genuine Helical® components to ensure OEM-level reliability, consistent valve operation, and long-term customer confidence. We believe the quality of every component should match the engineering standards expected by Porsche enthusiasts.
