Key Features:

Catless Design for Maximum Flow
This full catless configuration removes the OEM catalytic converters entirely, opening up the exhaust path for minimal restriction and maximum velocity. Expect faster turbo spool, increased horsepower and torque, and immediate throttle response.

Integrated Heat Shielding
Equipped with an integrated thermal barrier, this downpipe helps insulate radiant heat away from sensitive engine bay components. This shielding protects wiring, hoses, and surrounding parts while maintaining consistent performance under prolonged heat exposure and spirited driving.

Aggressive Exhaust Note
With the factory restrictions gone, the 720S’s 4.0L twin-turbo V8 comes alive with a louder, sharper, and more exotic exhaust tone. You’ll hear amplified turbo spool, aggressive crackles, and a more visceral soundtrack every time you get into the throttle.

Track-Proven Construction
Fabricated from T304 stainless steel, this downpipe features precision TIG welds and CNC-machined flanges for a perfect fit and long-lasting durability—even under extreme temperature and pressure. It’s built to endure the demands of high-speed track use and high-horsepower builds.

Direct Bolt-On Installation
Designed to integrate seamlessly with OEM or aftermarket exhaust systems, this downpipe provides straightforward installation using factory mounting points. No cutting or custom fabrication required.
