Performance Catless Downpipes - Audi RS4/RS5 (2018-2022)

Unleash Maximum Turbo Performance

Your RS model's twin-turbo 2.9L V6 is capable of incredible power, but the factory downpipes create a significant bottleneck. These restrictive components were designed to meet emissions regulations, not maximize performance. By replacing them with our high-flow catless downpipes, you're eliminating that restriction entirely.

The result is transformative: dramatically reduced turbo lag, noticeably faster spool-up, and sharper throttle response throughout the rev range. When you press the accelerator, power arrives immediately—no waiting, no hesitation. The turbos build boost faster and more efficiently, delivering the kind of linear, explosive power that makes every drive exhilarating. This is what your RS was always meant to feel like.

The Aggressive RS Sound You've Been Craving

Audi's RS models have always been known for their distinctive five-cylinder roar in previous generations, but the modern twin-turbo V6 brings its own character—especially when freed from factory restrictions. Our catless downpipes unleash an aggressive, race-inspired exhaust note that announces your RS's performance credentials without apology.

Expect deep turbo whooshes, crackling overrun on deceleration, and a raw, mechanical symphony that connects you to the engine in ways the factory system never could. The sound is purposeful and aggressive—perfect for track days and spirited drives. This is the authentic RS experience that enthusiasts dream about, delivered through precision-engineered exhaust flow.

Premium 304 Stainless Steel Construction

We've engineered these downpipes to match—and exceed—the quality standards Audi maintains for RS models. Constructed from premium 304 stainless steel, these components are built to withstand extreme exhaust temperatures and corrosive conditions for years of reliable performance. The material choice ensures long-term durability while resisting discoloration and corrosion that plague lesser materials.

Every detail matters: smooth mandrel bends maintain consistent diameter throughout for maximum flow, CNC-machined flanges ensure perfect sealing and alignment, and larger piping diameter allows exhaust gases to exit with minimal restriction. The result is a downpipe system that flows substantially better than factory while maintaining the precision fitment and quality you expect from your Audi.

Intelligent Heat Management

High-performance driving generates significant heat, and managing that heat is crucial for maintaining power and protecting components. Our downpipes include OEM-style heat shields that protect your engine bay from excessive exhaust temperatures—just like the factory system, but optimized for increased flow.

Higher exhaust velocity means gases exit faster, which actually helps reduce under-hood temperatures while simultaneously improving turbo efficiency. The heat shields work in conjunction with this improved flow to keep your engine bay cooler during aggressive driving, protecting sensitive components and maintaining consistent performance even during extended track sessions.

Direct Bolt-On Installation

These downpipes are engineered for precise, direct replacement of your factory components. OEM-like bolt-up fitment means no cutting, no welding, no fabrication—just remove the restrictive factory parts and bolt these on. All mounting points align perfectly with your RS4 or RS5's existing exhaust system, ensuring a secure, leak-free installation.

The precision fitment also means you can reverse the modification if needed. Whether you're planning track days, considering a full exhaust system upgrade, or simply want maximum performance from your RS, these downpipes provide a professional-grade foundation.

Substantial Weight Reduction

Performance isn't just about power—it's about power-to-weight ratio. Our catless downpipes save substantial weight compared to the heavy factory catalytic converter assembly. Every pound removed from your RS improves acceleration, handling dynamics, and overall responsiveness. When you're carving through canyon roads or attacking a race track, that weight reduction translates to tangible performance advantages.
