High Flow Catless Downpipes w/ Heat Shield - Porsche 911 992 Carrera 3.0T 2019-2024

Upgrade the exhaust flow and performance character of your Porsche 911 992 Carrera 3.0T with these High Flow Catless Downpipes with Integrated Heat Shields. Designed to replace the restrictive factory downpipe assemblies, these performance downpipes provide a more direct exhaust path for reduced backpressure, sharper turbo response and a more aggressive exhaust note.

Constructed from high-temperature-resistant stainless steel and surrounded by protective heat shielding, the downpipes are engineered for demanding turbocharged applications. The catless configuration removes the factory catalytic converter restriction, making these components suitable for performance-focused, competition and off-road builds where permitted.

Key Specs

Features

• High Flow Catless Design: Eliminates the factory catalytic converter restriction to provide a more direct exhaust path and reduce exhaust backpressure.
• Turbocharged Performance Application: Designed for the 3.0L twin-turbo Porsche 992 Carrera platform and intended to support improved exhaust gas evacuation.
• Integrated Heat Shielding: External thermal shielding helps reduce radiant heat transfer to nearby engine bay and exhaust components.
• Stainless Steel Construction: Manufactured from heat-resistant stainless steel for durability in demanding high-temperature exhaust environments.
• Improved Exhaust Flow: Larger and less restrictive exhaust passages are designed to improve flow compared with the factory catalytic downpipe assemblies.
• Aggressive Exhaust Character: The catless configuration produces a louder, sharper and more pronounced exhaust tone compared with the factory system.
• Performance-Oriented Response: Reduced exhaust restriction may contribute to quicker turbo response and improved throttle characteristics when combined with an appropriate vehicle setup.
• Vehicle-Specific Geometry: Formed to match the exhaust routing and mounting configuration of compatible Porsche 911 992 Carrera models.
• Pair Configuration: Supplied as matching left and right downpipe assemblies for the twin-turbo exhaust system.

Fitment Note: These downpipes are intended for Porsche 911 992 models equipped with the compatible 3.0L twin-turbo exhaust configuration. Exhaust hardware, sensors and connection points may vary by model year, trim and market. Verify the vehicle VIN, engine configuration and original downpipe layout before ordering.

Emissions Notice: This product removes the factory catalytic converters and may not comply with emissions or road-use regulations in your jurisdiction. It is intended for off-road, competition or closed-course use where legally permitted. Check all applicable local laws before installation or use.

Installation

Installation requires removal of the original factory downpipes and connection of the replacement assemblies to the turbocharger outlets and downstream exhaust system. Professional installation is strongly recommended due to the confined installation area, high-temperature components, exhaust sensors and precise alignment required.

After installation, inspect all exhaust joints, clamps, brackets and sensor connections for proper clearance and leaks. ECU calibration or additional modifications may be required depending on the vehicle configuration and intended use.

Production & Shipping

Care Guide

Regular Inspection: Periodically inspect the downpipes, heat shielding, clamps and mounting hardware for looseness, exhaust leaks or signs of excessive heat exposure.

Keep Components Clean: Allow the exhaust system to cool completely before cleaning. Use a soft cloth and a suitable metal-safe cleaner to remove dirt, road residue or contaminants from exposed stainless steel surfaces.

Inspect Heat Shielding: Check the thermal shielding periodically to ensure it remains securely attached and has not been damaged by road debris, vibration or repeated heat cycles.
