Unlock the full power potential of your BMW M2, M3, or M4 (G80/G82) with the Untd. Performance Catless Downpipe V1, designed specifically for the S58 twin-turbo 3.0L inline-6. This first-generation, race-inspired downpipe is built for enthusiasts who demand unfiltered sound, maximum flow, and the most responsive turbo experience possible.
Key Features:
Catless Design for Unrestricted Flow
By removing the factory catalytic converter, this downpipe maximizes exhaust gas velocity and minimizes backpressure. The result: quicker turbo spool, increased horsepower, and sharper throttle response—perfect for tuned and high-boost applications.
Raw, Motorsport-Inspired Exhaust Note
The V1 Catless Downpipe transforms your M car’s exhaust tone into something truly fierce. Turbo spool is louder, overrun crackles are more aggressive, and the sound overall is raw and race-ready—exactly what you expect from a true performance build.
Dyno-Proven Gains & Enhanced Driveability
Expect a noticeable bump in power and torque throughout the rev range, especially when paired with ECU tuning. The reduction in lag and faster turbo response makes the car feel livelier and more urgent at all throttle inputs.
Durable Stainless Steel Construction
Made from high-grade 304 stainless steel, this downpipe is TIG-welded for strength and features CNC-machined flanges for a perfect fit. Built to handle the intense heat and pressure of a performance-driven S58 engine.
Track-Focused Fitment
Designed for a clean bolt-on installation, the V1 Downpipe fits seamlessly to the factory turbo and mid-pipe connections. No cutting, no welding—just a direct performance upgrade for your modern M.
Compatibility:
Whether you’re prepping for the track or pushing your build to the next level, the Untd. Performance Catless Downpipe V1 is the ideal foundation for unlocking your S58’s full performance capabilities. Loud, fast, and purpose-built—this is the sound and speed your M car deserves.
