Valved Side Muffler Bypasses
A bolt-on replacement for the 992.2 Turbo and Turbo S's factory left and right valved side mufflers, cutting 18 lbs while adding a dyno-measured 8 hp and 12 lb-ft at the wheels and a deeper, more aggressive exhaust note. Because it's a true cat-back system that leaves every emissions component untouched, it's 100 percent emissions-legal and CARB-exempt, and it retains full factory exhaust valve control. Every system uses genuine Helical electric valve actuators, the same UK-made units trusted by McLaren, Ferrari, Aston Martin and Porsche's own GT models, built from T304L stainless steel to OEM-quality fitment.
