If you're looking to unlock the true potential of your MK8 Golf R, the ECS Race Cat-Back Exhaust System is the upgrade you've been waiting for. Designed to deliver a significant boost in exhaust flow and performance, this system is the loudest emissions-compliant exhaust available for your vehicle. Whether you're after a more aggressive sound or increased horsepower, this system has it all.

Design and Engineering:

Our goal in developing the Race Cat-Back Exhaust was simple: to maximize exhaust volume while producing a refined, aggressive sound. We achieved this by using a full 3" piping design for both resonated and non-resonated mid-pipe options, providing a drastic increase in exhaust flow compared to the factory system. The 3" ECS Midpipe is engineered to enhance gas expulsion and minimize backpressure for improved performance.

The axle-back section is outfitted with quad 2.5" tailpipes, crafted to fit 4" exhaust tips while ensuring perfect compatibility with your factory valence.

Key Features:

• In-House Design: Created using FARO ARM laser scanning technology and SolidWorks 3D CAD modeling, ensuring a precise fit for your MK8 Golf R.
• High-Quality Materials: Constructed from 3.0" T304 stainless steel with CNC mandrel-bent tubing and 1.25mm wall thickness for durability and performance.
• TIG-Welded Construction: Each exhaust system is TIG-welded and back-purged to guarantee superior strength and a clean, polished appearance.
• Optional Resonator: An optional wool-packed resonator reduces unwanted drone for a more refined sound without sacrificing performance.
• Straight-Through Design: The system features a straight-through 3.0" flow path that leads into quad 2.5" tailpipes, minimizing restriction and turbulence.
• OEM Fitment: T304 stainless steel 12mm barbed exhaust hangers are TIG-welded in OE locations for precise fitment.
• Ground Clearance Compatibility: Designed to maximize ground clearance, making it compatible with aftermarket components like larger rear sway bars.

Kit Contents:

• OEM (65mm) downpipe adapter
• Accuseal-style exhaust clamps (4)
• OEM diameter (65mm) sleeve clamp
• 3.0" Resonator/Midpipe Assembly (choose between resonated for quieter operation or non-resonated for louder sound)
• Race Axle-Back Assembly
• ECS 4.0" Swivel Exhaust Tips (choose from Chrome, Black Chrome, Carbon Fiber, Titanium (Matte), or Titanium (Burnt))

Development Process:

The ECS Race Cat-Back Exhaust System was developed in-house at our Wadsworth, Ohio facility. Our team used cutting-edge technology to ensure precision and quality at every step of the process. This includes FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling for detailed design, and in-house rapid prototyping with our 3D printer. Rigorous long-term product testing ensures that every exhaust system meets our high standards of performance and durability.
