Valved Rear central Exhaust – .1 – Porsche 911 (991 PSE / 991)

The entire sound of the 991 lives in this rear centre muffler – nothing in the side mufflers. This valve version delivers a very powerful sound with the valves open and stays close to stock with them closed. All our 991 mufflers have an adjustable side for a stress-free fit.

Fitting

• Strictly original interfaces (inlets, outlets, dimensions): direct replacement of the original part
• Mounts directly at the catalytic converter outlets
• Average fitting time: 8 hours including removal. The rear bumper must come off: the air filters are accessible there, a good opportunity to switch them to sport versions
• A lift is preferable but not essential; removing the original exhaust is fairly easy
• Tighten all nuts progressively, then the clamp last
• Fitting kit included: gaskets, stainless bolts, stainless lock nuts, high-temperature copper grease and the 2 straps
