Key Features:

200-Cell High-Flow Cat for Performance & Emissions Compliance
The Untd. Performance Catted Downpipe features a 200-cell high-flow catalytic converter, which offers the best of both worlds—enhanced performance and legal emissions compliance. The high-flow design helps reduce turbo lag and provides smoother exhaust flow, allowing the S63 engine to spool quicker and make more power, while still adhering to regulations in regions where emissions control is necessary.

Heat Shield for Added Protection & Durability
Equipped with a heat shield, this downpipe ensures the surrounding components of your exhaust system stay protected from extreme temperatures. The shield helps maintain optimal exhaust flow temperatures, reducing the risk of heat damage to nearby parts and improving the overall lifespan and reliability of the system, especially under heavy loads and high-performance driving conditions.

Increased Power & Turbo Response
By improving exhaust flow, this downpipe enables faster turbo spool, reduces turbo lag, and helps the turbos breathe easier at higher boost levels. The result is improved throttle response and a noticeable increase in horsepower and torque across the entire RPM range, providing the performance gains needed to elevate your driving experience to the next level.

Aggressive Exhaust Sound with a Refined Tone
With the catted design, the Untd. Performance Downpipe delivers an aggressive, sporty exhaust note that’s more refined compared to catless alternatives. Turbo spool sounds are sharper, and there are more pronounced pops and crackles on deceleration. Enjoy a more motorsport-inspired soundtrack without sacrificing too much on noise levels for daily driving comfort.

Premium Stainless Steel Construction
Built with high-quality 304 stainless steel, the Catted Downpipe with Shield is engineered to endure the high temperatures and pressures typical of high-performance applications. It’s TIG-welded for durability and long-term reliability, and the flanges are CNC-machined to ensure a precise, leak-free fit. This construction makes the downpipe resilient to corrosion, ensuring a long-lasting performance upgrade.

Direct Bolt-On Fitment
The Untd. Performance Catted Downpipe with Shield is designed for a direct bolt-on installation, making it easy to install without any modifications. It bolts directly to the S63 engine’s turbos and mid-pipes, ensuring a quick, hassle-free upgrade. No welding or cutting is required, allowing you to get back on the road or track with minimal downtime.
