Key Features:

Catless, High-Flow Design
By eliminating the factory catalytic converters, this downpipe drastically reduces backpressure and heat retention. The result is faster turbo spool, improved efficiency, and increased power throughout the rev range—especially noticeable under load or when tuned.

Enhanced Exhaust Sound
With the restrictive cats removed, the M276’s twin-turbo V6 gains a louder, deeper tone with sharper turbo whistle and pronounced crackles during shifts and deceleration. It brings a more aggressive and thrilling exhaust note to your luxury SUV.

Track-Proven Construction
Crafted from TIG-welded 304 stainless steel and built to handle extreme heat and high-boost environments. CNC-machined flanges ensure leak-free connections and a precise, bolt-on fit to factory or aftermarket exhaust systems.

Designed for Power Builds
Ideal for vehicles running ECU tunes or full bolt-on setups, this catless downpipe allows your M276 to operate at peak efficiency while unlocking hidden performance. Whether you’re towing, launching, or daily driving, it delivers consistent gains.

Direct Bolt-On Installation
Engineered to fit factory turbo and exhaust locations without modification. Designed for a smooth install with all OEM mounting points retained.
