APR Catback Exhaust System for Mk8 GTI | CBK0047

The APR Catback Exhaust System (CBK0047) is the premier exhaust upgrade for the Volkswagen MK8 GTI, engineered to enhance the vehicle's aesthetic, performance, and acoustic profile. Hand-crafted from premium T304 stainless steel with meticulous TIG welding, this system features a 3" (76mm) mandrel-bent primary pipe that transitions into dual 2.5" (63.5mm) exits. This design provides a piping cross-sectional area up to 60% larger than stock, significantly reducing backpressure and allowing the engine to breathe more freely.

Sound quality is a priority for APR; the system utilizes a straight-through, brushed-finish muffler paired with a drone-eliminating Helmholtz resonator. This combination ensures a deep, sporty growl under acceleration while maintaining a sophisticated, drone-free experience during highway cruising. The system is finished with massive 4" (102mm) polished slash-cut tips, which are removable and compatible with APR’s optional double-wall tips in various finishes.

Key Features:

• High-Flow Engineering: 3" (76mm) mandrel-bent tubing offers 60% more cross-sectional area than the factory system.
• Drone-Free Performance: Integrated Helmholtz resonator targets and cancels out cabin drone for a refined driving experience.
• Premium Materials: Full T304 stainless steel construction with high-quality TIG welds for maximum corrosion resistance.
• Weight Reduction: Performance-focused design results in a system that weighs 9% less than the bulky factory exhaust.
• Motorsport Aesthetics: Features 4" (102mm) polished slash-cut tips for a bold, aggressive rear profile.
• Low-Profile Design: Optimized for lowered vehicles to ensure maximum ground clearance.
• Easy Installation: 100% bolt-on, plug-and-play design with rugged mounting brackets and OEM-style slip clamps.
