Unleash the hidden performance of your Porsche Panamera 2.9T with the Untd. Performance Catless Downpipe—engineered to extract maximum power, throttle response, and sound from the twin-turbocharged V6. By removing the factory catalytic converters, this high-flow downpipe eliminates restriction, enhances turbo spool, and delivers a more aggressive exhaust note—all while setting the stage for serious tuning and performance builds.
Catless, Free-Flowing Design
The restrictive OEM catalytic converters are replaced with a straight-through, high-velocity pipe to dramatically reduce backpressure. The result: improved exhaust flow, quicker turbo response, and greater horsepower and torque throughout the rev range.
Faster Turbo Spool & Sharper Throttle Response
This downpipe allows your twin turbos to spool significantly faster, reducing lag and delivering immediate power when you need it. Mid-range torque and top-end pull see noticeable gains, especially when combined with a performance ECU tune.
Aggressive, Sporty Exhaust Note
Removing the cats uncorks the Panamera’s 2.9L twin-turbo V6, giving it a louder, deeper, and more performance-oriented tone. Expect pronounced turbo spool, sharper overrun pops, and a thrilling exhaust note that brings the luxury sport sedan to life.
Precision-Built with 304 Stainless Steel
Constructed from premium TIG-welded 304 stainless steel, this downpipe is made to withstand extreme temperatures and boost pressure. CNC-machined flanges ensure a leak-free seal and easy bolt-on fitment with factory or aftermarket exhaust systems.
Optimized for High-Performance Builds
Whether you’re upgrading for track use, dyno tuning, or aggressive daily driving, this downpipe is designed to support higher boost levels and maximum efficiency from your Panamera’s twin-turbo setup.
