Unlock raw sound, serious power, and pure turbo efficiency with the Untd. Performance Cat-Less Test Pipe for the Porsche 911 (991.2) 3.0L Twin-Turbo H6. Designed for enthusiasts who demand maximum performance and zero restrictions, this test pipe replaces the factory catalytic converter with a high-flow, straight-through design that lets your 3.0T engine breathe — and scream.
This isn’t just an upgrade — it’s a transformation.
Full Cat-Less Design for Maximum Flow:
Eliminate the bottleneck. By removing the factory catalytic converter, this test pipe dramatically reduces backpressure, improves exhaust flow, and allows your turbos to spool quicker and hit harder across the powerband.
Pure, Unfiltered Exhaust Sound:
Experience the 911’s twin-turbo flat-six like never before. The cat-less setup unleashes an aggressive, motorsport-inspired exhaust note that crackles, snarls, and roars with every gear change. It’s raw. It’s loud. And it’s 100% authentic.
Boosted Turbo Response:
With reduced restriction, your turbos spool up noticeably faster, throttle response sharpens, and mid-range power becomes even more explosive. Perfect for street warriors, track addicts, and dyno kings alike.
Race-Ready Construction:
Built from high-quality stainless steel and precision TIG welded, this test pipe is made to handle the extreme heat and pressure of high-performance driving. Whether you’re chasing lap times or carving up canyons, it’s ready to go.
Lightweight Performance Gain:
Shedding unnecessary weight while increasing flow is a win-win. This test pipe not only improves power and sound but also reduces overall exhaust system weight for better performance balance.
Direct Bolt-On Fitment:
Designed to install seamlessly in place of the factory cat section with no cutting or permanent modifications. Works with OEM and most aftermarket exhaust setups.
Tune Required:
Due to the cat-less nature of this product, an ECU tune is required to prevent check engine lights and to fully optimize your engine for the increased flow.
If you’re after maximum performance, brutal sound, and turbo spool that hits like a sledgehammer, a cat-less test pipe is the ultimate power mod for your 991.2. It’s the most direct route from stock to savage.
Compatibility:
Porsche 911 Carrera / Carrera S / Carrera 4 / 4S / T / GTS (991.2)
3.0L Twin-Turbocharged Flat-6 Engine (2017–2019)
Take your 911 to the next level with the Untd. Performance Cat-Less Test Pipe — pure performance, no compromises.
