Product Description

 

 

Upgrade your 2022+ Porsche 911 GT3 (992 chassis) with this all-in performance exhaust system package from Kline Innovation. Designed specifically to extract maximum performance and unleash the full character of the flat-six engine, it addresses the factory restrictions (including the OPF/filter section and the catalyst internals) by replacing them with full long-tube headers and high-flow silencer sections. The result: sharper throttle response, increased power, deeper and more aggressive exhaust tone, and a serious reduction in overall weight. Finished in premium materials with multiple configurations (304 stainless, Inconel 625, differing catalyst densities) the package offers serious build flexibility for street/track builds.

Fitment Notes

  • Fits 2022 and onward Porsche 911 GT3 (992 chassis) models as listed. 

  • Available in multiple material options: 304 stainless steel (100 cell), 304 stainless (200 cell), 304 stainless Race, Inconel 625 (100 cell), Inconel 625 (200 cell), Inconel 625 Race. 

  • When selecting Race headers, note that the system may be suited for track-use or non-street legal jurisdictions (verify local regulations).

  • Because this is a full header + silencer package, ECU tuning or adaptation may be required for optimal performance and to avoid error codes when removing OPF/cat restrictions.

Included

  • Full Kline Innovation exhaust system package for 992 GT3, including: long-tube headers (or manifold section), X-pipe section, silencer/muffler section (depending on configuration), and exhaust tips (carbon or stainless depending on selection) 

  • All necessary gaskets, clamps and mounting hardware specific to the 992 GT3 installation.

  • Carbon or stainless exhaust tips

Product Specs

  • Power/torque gains: With 100-cell catalyst option, gain is stated up to +25 hp and +32 Nm. With the Race long tube header option, gain up to +31 hp and +38 Nm. 

  • Materials & weight: Options include 304 stainless steel, Inconel 625 super-alloy (F1-grade), each with ultra-thin side-wall construction for reduced weight. 

  • Catalyst density options: 100 cell, 200 cell or “Race” 

  • Sound character: Kline describes the system as delivering “a raucous, yet beautiful incendiary scream” through optimized X-pipe and thin side-wall Inconel construction that raises the pitch of the exhaust at high revs.

Product Features

  • Multiple material configurations – Choose from 304 stainless steel or Inconel 625 for weight savings, heat resistance and sound tone, depending on your build goals.

  • High-flow design with minimal restrictions – The long-tube header section, optimized X-pipe, and choice of catalyst densities (100/200/race) are engineered to maximize flow, minimize back-pressure and boost mid/high RPM performance.

  • Aggressive exhaust tone & track-sound character – The thin wall construction (especially in Inconel) resonates to produce a higher pitched, race-inspired tone without excess drone.

  • Bolt-on fitment for the 992 GT3 – Engineered specifically for the 992 GT3 model, ensuring correct mounting points, fitment and integration with factory components where needed.

  • Premium finish & aesthetics – Carbon or stainless tips included, ultra-thin wall construction and premium materials underline a high‐end build quality.

  • Tuned for serious performance – Documented gains of up to 31 hp and 38 Nm affirm this system is more than just sound — it’s built for performance focus.
