Performance High-Flow Catless/Catted Downpipe w/ Heat Shield - Porsche Cayenne 9Y0 3.0T V6 2019+

Upgrade the turbo performance, exhaust flow, and sound of your Porsche Cayenne 9Y0 3.0T V6 with this Performance High-Flow Catless/Catted Exhaust Downpipe with Integrated Heat Shield. Designed for 2019+ Cayenne 3.0L Turbo V6 models, this performance downpipe reduces exhaust restriction while improving turbo response and delivering a more aggressive exhaust character.

Available in both Catless and 200-cell High-Flow Catted configurations, the downpipe allows you to select the setup that best suits your performance build. Its integrated thermal shielding helps manage radiant heat around the turbo and nearby engine-bay components.

Key Specs

Key Features

• Catless or High-Flow Catted Options: Choose a catless configuration for maximum exhaust flow or the 200-cell high-flow catalytic converter configuration for a more street-oriented setup.
• Integrated Heat Shield: Thermal shielding surrounding the downpipe helps reduce radiant heat and provides additional protection for nearby engine-bay components.
• T304 Stainless Steel Construction: Built from durable, corrosion-resistant stainless steel with performance-oriented welded construction.
• Improved Exhaust Flow: Designed to reduce restriction downstream of the turbocharger and provide a freer-flowing exhaust path.
• Improved Turbo Response: Reduced exhaust restriction can help improve turbo spool characteristics and throttle response, particularly when paired with appropriate engine tuning.
• Performance Exhaust Sound: Produces a deeper and more aggressive turbocharged exhaust note with increased turbo sound compared with the factory setup.
• OEM O2 Sensor Ports: Includes provisions for the factory oxygen sensors for proper installation.
• Direct Bolt-On Fitment: Engineered specifically around the Cayenne 9Y0 3.0T V6 platform and designed to utilize factory mounting locations.

Configuration Options

Catless: Designed for maximum exhaust flow and performance. Intended primarily for motorsport or off-road applications where legally permitted.

High-Flow Catted: Equipped with a 200-cell sport catalytic converter to provide increased exhaust flow while retaining a catalytic converter.

Installation

The downpipe is designed as a direct bolt-on upgrade using factory mounting locations and includes provisions for the OEM oxygen sensors. Professional installation is recommended to ensure proper alignment, sealing, sensor installation, and heat-shield clearance.

Important: ECU calibration may be required depending on the selected configuration and vehicle setup. Catless or high-flow catalytic converter configurations may not comply with emissions regulations in all locations. Verify applicable regulations before installation or road use.

Care Guide

Routine Inspection: Periodically inspect the downpipe, mounting hardware, flanges, welds, heat shielding, and oxygen sensor connections.

Check for Exhaust Leaks: Inspect connection points after installation and periodically during use to ensure all clamps and hardware remain properly secured.

Keep Components Clean: Remove accumulated dirt, road contaminants, and debris using appropriate automotive cleaning products once the exhaust system is completely cool.

Avoid Abrasive Cleaning: Do not use aggressive abrasives that could damage the stainless steel surface or thermal shielding.
