Invidia 17+ Honda Civic Type-R FK8 76mm Downpipe w/ High Flow Cat

Unlock true turbo performance with the Invidia Downpipe with High Flow Catalytic Converter—a critical upgrade for any forced induction platform looking to unleash horsepower, torque, and response. The OEM downpipe is one of the most restrictive components in a turbocharged exhaust system, bottlenecking flow directly after the turbo. Invidia solves this by replacing the factory unit with a free-flowing design engineered to minimize backpressure and maximize velocity.

At the heart of the system is a high-efficiency, low-cell-count metallic catalytic converter, which maintains emissions compliance while drastically reducing restriction compared to stock. This high flow cat allows for significant gains in turbo spool, throttle response, and peak output—especially when paired with a proper tune. The result is faster turbo response, higher boost thresholds, and a deeper, more aggressive exhaust tone.

Constructed from mandrel-bent SUS304 stainless steel with large diameter piping, the Invidia downpipe is TIG-welded for durability and optimal flow geometry. A precision-machined turbo flange ensures perfect mating with your turbocharger, while the integrated O2 bungs allow seamless connection to factory or aftermarket sensors. Whether you’re aiming for track records or just want to wake up your daily driver, this downpipe is one of the most impactful upgrades you can make.

For enthusiasts seeking power, response, and emissions-friendly performance, the Invidia High Flow Catted Downpipe is the ideal balance between performance gains and street legality.

• High-flow metallic catalytic converter increases power while retaining emissions compliance
• SUS304 stainless steel construction with TIG welds for strength and longevity
• Mandrel-bent large diameter piping ensures unrestricted flow from the turbo
• Direct bolt-on design with O2 sensor provisions for easy install and compatibility
