Capristo Valved Muffler w/ Carbon Tips for 992 Porsche 911 GT3 & GT3 RS

Designed for the 992 GT3 and GT3 RS, the Capristo Valved Muffler with Carbon Tips elevates the soundtrack while shedding 9.7lbs versus the OEM unit and delivering gains of up to 9.8hp. Utilizing the factory valve actuators preserves OE driving modes — quiet when cruising, assertive under load — while the carbon outer shell and anodized inner tips (available in black, silver, or red) add a motorsport finish. Engineered for precise fitment, it’s a clean, performance-forward upgrade that blends power, control, and premium aesthetics.

Valve System

• The system uses vacuum-actuated valve flaps that adjust with driving conditions and driver input: at lower engine speeds or steady cruising the valves stay closed for a deeper, more restrained tone, while at wide-open throttle they open fully to unleash the engine’s full soundtrack. For the 992 application, Capristo’s electronically controlled valves integrate the OEM actuators to maintain factory operation via Sport Control, providing precise sound management to suit driver preference—without additional electronics, modules, or remotes.

Engineering

• Capristo Exhaust systems stand as a testament to engineering prowess, fusing innovative techniques such as 3D Laser-Scanning, CAD Design, Digital modeling, and CNC precision in their respected German facility. Each component is delicately shaped from the premium T309 (1.4828) stainless steel, and then attentively hand-polished, giving it a lustrous finish. Post detailed analysis, this distinct alloy was chosen due to its superior sound quality, lightness, and durability  —  characteristics that echo the Inconel qualities seen in elite Formula 1 challenges.
