For more information, visit www.P65warnings.ca.gov.The APR MK8 Golf R Catback Exhaust System (CBK0052) is the definitive upgrade for enthusiasts seeking a perfect balance of luxury aesthetics and aggressive performance. Engineered from the ground up using advanced 3D sound spectrographs, this system delivers a ferocious roar under wide-open throttle while maintaining a civilized, drone-free environment during highway cruising. Constructed entirely from brushed T304 stainless steel, the system features a massive 3” main pipe that splits into quad 2.5” exits, finished with high-end matte carbon fiber tips.
What sets this system apart is its "Performance Without Compromise" approach to sound. By utilizing dual Helmholtz resonators and retaining OEM-controlled exhaust valves, APR engineers have successfully canceled out unwanted frequencies without the use of sound-absorbing packing materials that can degrade over time. When the valves are open, the system is 100% unrestricted, significantly outperforming the factory exhaust—which narrows to 50mm—and providing measurable gains in both horsepower and turbocharger response.
Key Features:
- Premium Quad Tips: Large 5.2" x 3.9" (131mm x 99mm) matte carbon fiber tips with stainless steel inlays for a high-end, exotic look.
- Drone-Free Technology: Dual Helmholtz resonators specifically tuned to eliminate cabin drone while maintaining a pure exhaust note.
- Valved Design: Fully compatible with factory OEM exhaust valve actuators, allowing you to retain the vehicle's original driving mode sound profiles.
- Unrestricted Flow: Straight-through 3” (76mm) mandrel-bent tubing provides a significant flow increase over the restrictive stock system.
- T304 Stainless Construction: Durable, corrosion-resistant T304 stainless steel used throughout the entire system for long-term reliability.
- Verified Power Gains: Provides peak gains of +5 AWHP and +4 FT-LBS of torque at all four wheels.
- Bolt-On Installation: Low-profile butt clamps and precision TIG-welded brackets ensure a perfect, no-cut fitment with the factory downpipe.
