By eliminating the restrictive factory catalytic converter, the Untd.

This downpipe is perfect for high-performance builds, track days, or for those who demand the highest level of performance from their BMW B58 engine.

Key Features:

Catless Design for Maximum Flow
The catless design eliminates the factory catalytic converter, drastically improving exhaust flow by reducing backpressure. This results in faster turbo spool, more responsive throttle, and significant power gains throughout the RPM range. Ideal for high-performance builds, the absence of a catalytic converter allows the engine to breathe more freely, optimizing turbo efficiency and increasing overall horsepower and torque.

Aggressive Exhaust Sound
With the catalytic converter removed, this downpipe amplifies the aggressive exhaust note of your BMW B58 engine. Expect a deeper, more menacing tone under acceleration, with pronounced turbo spool sounds, crackles, and pops on deceleration. The result is a motorsport-inspired exhaust sound that will turn heads wherever you go.

Enhanced Turbo Performance
The Untd. Performance Catless 4.5″ Downpipe is designed to improve turbocharger performance. The larger 4.5″ diameter allows for more air to flow out of the engine, reducing turbo lag and enabling faster spool times. This translates to immediate power delivery and improved acceleration, especially at higher RPMs. Whether you’re cruising on the highway or pushing your BMW on the track, you’ll experience noticeable improvements in turbo efficiency and throttle response.

Durable 304 Stainless Steel Construction
Constructed from high-quality 304 stainless steel, this downpipe is built to withstand high temperatures and harsh driving conditions. Its corrosion-resistant nature ensures long-lasting durability, and the precision welds and CNC-machined flanges guarantee a perfect fit and secure installation.

Easy Installation & Direct Fitment
This catless downpipe is designed to be a direct replacement for the factory downpipe, offering a hassle-free installation process. The included hardware (gaskets, bolts, etc.) ensures a secure fit, and no additional modifications are required for installation. The bolt-on design ensures a clean and straightforward upgrade for BMW enthusiasts.

Track-Ready Performance
Purpose-built for high-performance applications, the catless downpipe delivers unfiltered power that’s perfect for racing, dyno tuning, and track days where emissions compliance is not required. It is the ultimate solution for drivers who demand the most from their BMW, whether you’re on a spirited drive or pushing the limits on a racetrack.
