Kline Innovation Valvetronic Exhaust System for 992.2 Porsche 911 Carrera GTS Hybrid

Kline Innovation Valvetronic Exhaust System for 992.2 Porsche 911 Carrera GTS Hybrid

Kline Innovation regards the Porsche 992.2 GTS 3.6 Hybrid as a compelling blend of progressive and retro design, combining a twin-turbo flat-six with two electric motors to deliver 541hp and sub-3-second 0-60 performance. While the factory exhaust is subdued by OEM and emissions constraints, Kline Innovation specializes in liberating turbocharged sound engineering lightweight, precision systems that transform the note from muted to an exotic, motorsport-inspired wail.

The Sound

• Kline Innovation replaces the heavy, chambered rear silencer with an ultra-light, F1-grade Inconel 625 X-pipe and fully bypassable Inconel silencers, shedding substantial weight while elevating the pitch into a more exotic tonal range. For track-use configurations, substituting the OPF and factory catalysts with HJS Motorsport high-flow pipes or race sections further opens the soundtrack, amplifying the high-frequency character into an authentic supercar-style scream. The rear valvetronic architecture enables discreet, near-stock manners with valves closed and an unfiltered, raw voice with valves open, while beautifully crafted F1-grade pre-preg carbon fiber tips complete the system.

Performance

• Kline Innovations notes that Porsche’s turbocharged platforms offer exceptional headroom for tuning. Replacing the stock pipes with Kline de-cat sections and recalibrating air–fuel ratios can yield gains of 40+ hp and 55 Nm of torque, while a full ECU remap can push total improvements toward 80 hp.
