High-Flow Catalytic Converter
Unlike restrictive OEM cats, the Untd. Performance downpipe uses a premium high-flow catalytic converter that maintains emissions-friendliness while dramatically improving exhaust flow. This setup is ideal for drivers seeking gains in power and response while keeping drone and excessive noise in check.
Enhanced Power & Turbo Response
Engineered to reduce backpressure and increase flow, this catted downpipe allows the M276 engine’s twin turbos to spool faster and more efficiently. Throttle input feels more immediate, torque delivery is smoother, and top-end power is noticeably stronger—especially when paired with a performance tune.
Refined Yet Sporty Exhaust Tone
Enjoy a deeper, more aggressive exhaust note without the harshness of a fully catless system. The high-flow cat provides a refined tone that enhances the engine’s sound under load, while maintaining a comfortable cabin experience for daily driving and long-distance cruising.
Durable 304 Stainless Steel Construction
Made from high-grade 304 stainless steel, this downpipe is built to withstand the rigors of high-boost, high-heat conditions. TIG-welded seams and CNC-machined flanges ensure long-term durability, leak-free performance, and straightforward bolt-on installation.
Ideal for Street & Performance Builds
This is the perfect downpipe for enthusiasts who want reliable, street-friendly performance without going fully catless. Whether you’re running an upgraded tune, custom exhaust, or planning future mods, this downpipe provides a solid foundation for performance gains with minimal compromise.
