Unleash the full potential of your 992-generation Porsche 911 with the Untd. Performance Catless Downpipe, engineered for the 3.0L twin-turbocharged DFI (Direct Fuel Injection) flat-six. Designed to eliminate factory restrictions and maximize exhaust flow, this catless downpipe delivers dramatic gains in turbo response, power, and sound—perfect for enthusiasts looking to elevate their 911’s performance and character without compromise.
Catless High-Flow Design
The restrictive factory catalytic converters are removed in favor of a straight-through, high-velocity design that reduces backpressure and unlocks significant gains in exhaust flow. This allows the twin turbos to spool quicker, increasing throttle response and enhancing acceleration across the rev range.
Sharper Turbo Response & Power Delivery
By minimizing exhaust restriction, this downpipe improves low-end torque and midrange punch while allowing for more efficient boost delivery. When paired with a proper tune, expect substantial increases in both horsepower and torque, along with faster turbo ramp-up.
Raw, Motorsports-Inspired Sound
The catless setup transforms the 3.0L DFI flat-six into an aggressive, free-breathing powerhouse. Turbo spool is more audible, downshifts deliver sharper crackles, and the overall exhaust note becomes deeper, louder, and unmistakably more thrilling—especially at wide-open throttle.
Heat-Resistant 304 Stainless Steel Construction
Fabricated from TIG-welded 304 stainless steel and finished with CNC-machined flanges for a perfect fit, this downpipe is designed to handle the extreme heat and pressure of high-performance applications—on the street or at the track.
Track-Focused Performance
Whether you’re tuning for maximum street performance or pushing the limits on track days, this catless downpipe is the ideal foundation for custom builds, larger turbos, or aggressive ECU calibrations.
