With integrated thermal shielding and a catless design, it’s made for drivers who demand unfiltered performance.
Key Features:
Catless Design for Peak Flow and Power
Eliminating the factory catalytic converter removes exhaust restrictions and significantly improves flow. This allows the turbos to breathe more freely, resulting in increased horsepower, faster spool, and more aggressive boost response—ideal for tuned or high-performance builds.
Integrated Heat Shield for Thermal Protection
High-performance means high heat. That’s why this downpipe includes a precision-fitted thermal shield to protect nearby components and reduce heat soak in the engine bay. Whether you’re on the track or stuck in traffic, this added protection helps maintain performance and reliability.
Sharper Turbo Response & More Torque
The reduced backpressure from the catless design enables quicker turbo spool and immediate throttle response. You’ll feel more torque down low and a more responsive powerband throughout the rev range, perfect for both spirited driving and track use.
Unleashed, Motorsport-Inspired Exhaust Tone
Free-flowing and catless, this downpipe delivers a louder, deeper, and more raw exhaust note. Expect enhanced turbo sounds, aggressive crackles, and a race-inspired character that transforms the driving experience of your S58-powered BMW.
Durable 304 Stainless Steel Construction
Crafted from TIG-welded 304 stainless steel, this downpipe is built to withstand the high temps and pressures of turbocharged performance driving. CNC-machined flanges ensure a perfect, leak-free fit and long-lasting reliability under extreme conditions.
Direct Bolt-On Installation
Engineered for easy, bolt-on fitment, this downpipe installs directly to the factory turbo and mid-section without the need for cutting or modification. It’s a true plug-and-play performance upgrade.
Compatibility:
For G-series M owners ready to take performance, sound, and response to the next level, the Untd. Performance Catless Downpipe with Shield is the ultimate power mod. Built to perform, engineered to fit, and tuned to thrill.
