Introducing the APR MK8 Golf R Catback Exhaust System—a masterpiece crafted by enthusiast engineers who were given complete freedom to create an unparalleled exhaust system. The mission was clear: design the ultimate system that enthusiasts would desire. Prioritizing quality, style, sound, and features while keeping it accessible and affordable. Our team poured immense effort and months of development into this project. The result? A system that sets the gold standard for MK8 Golf R catback exhaust systems, and anyone who’s experienced it knows exactly why! The first thing that catches your eye is the system’s stunning appearance. The quality is evident at a glance—constructed from brushed T304 stainless steel with oversized 3” tubing that elegantly splits into quad 2.5” exits. Precision mandrel bending ensures a free-flowing design, while the matte carbon fiber quad tips add a touch of luxury typically reserved for vehicles twice the price! The system is packed with premium features: robust TIG welding and precision-engineered bracketry guarantee a perfect fit and alignment on every vehicle, every time. Our low-profile clamps simplify the installation, saving you time and money. Plus, the interchangeable tips offer customization options should you wish to switch up the look in the future. But it’s the sound of this system that truly excites us. At wide-open throttle, the exhaust unleashes a ferocious roar, yet it remains refined and civilized during daily driving and cruising. This perfect balance is achieved through straight-through tubing, OEM-controlled exhaust valves, dual Helmholtz resonators, and the absence of sound-absorbing materials that could alter the pure exhaust tone. When you floor the throttle, the valves open, channeling exhaust gases through a straight, unrestricted path, maximizing power and preserving the exhilarating soundtrack. However, when you’re cruising around town or embarking on a long highway journey, the valves close, and the Helmholtz resonators work their magic, canceling out unwanted drone frequencies as sound waves collide within the offset tubing. This isn’t just theory—our engineers utilized advanced 3D sound spectrographs to analyze and fine-tune the system’s frequencies, eliminating the tones nobody wants to hear. The result is a tone that’s as pleasant as it is powerful, ensuring an enjoyable driving experience for you and your passengers. Now that’s what we call Performance Without Compromise!

Features:

  • Premium Quad Exhaust Tips: Features quad 5.2x3.9” (131mm x 99mm) matte carbon fiber tips with stainless steel inlays, adding a high-end, customizable touch that exudes luxury.
  • All T304 Stainless Steel Construction: Constructed entirely from durable, brushed T304 stainless steel, ensuring long-lasting quality, resistance to corrosion, and a striking appearance.
  • Innovative Sound Engineering: Dual OEM-controlled valves and dual Helmholtz drone elimination resonators work together to deliver an exhilarating exhaust note at wide-open throttle while maintaining a civilized tone during cruising.
  • Unrestricted Performance: The straight-through 3” (76mm) to quad 2.5” (63.5mm) mandrel-bent tubing ensures maximum exhaust flow. 100% unrestrictive design with valves open significantly outperforms the factory system, which narrows to 50mm.
  • Optimized Power Delivery: Experience improved turbocharger response with peak gains of 5 AWHP and 4 FT-LBS of torque at all four wheels, enhancing acceleration and overall driving performance.
  • Pure Exhaust Sound: The system avoids packing or sound absorption materials, preserving the natural exhaust note. Advanced 3D spectrograph aided tuning to eliminate unwanted drone frequencies for a pleasant driving experience.
  • Exceptional Build Quality: Strong TIG welding throughout and precision bracketry ensure a perfect fit every time, with no sagging or misalignment, for a professional-grade installation at any skill level, every time.
  • Easy Installation: Low-profile butt clamps allow for a simple, no-cut installation, making it a plug-and-play upgrade with the factory system, including a removable reducer for seamless integration.
  • Customizable Tips: The exhaust tips are removable and can be swapped for other designs, giving you the freedom to tailor the system’s appearance to your personal style.

SYSTEM OVERVIEW

Our exhaust system uses larger piping compared to the factory exhaust system! We use 3" (76mm) OD piping, which then splits to duad 2.5" (63.5mm) piping. The factory system uses 2.76" (70mm) piping, which reduces to 2.56” (65mm) before entering the muffler. It then splits and exits the muffler as a quad 2.36” (60mm) system, but reduces down to 1.97” (50mm) just after exiting the muffler! These reductions greatly diminishing the overall cross-sectional area of the system. Internally to the rear resonator is our dual Helmholtz frequency eliminating chambers. With the valves open, exhaust gasses flow uninterrupted through the system, and when closes they travel through smaller pipes to reduce sound volume and cancel drone frequencies. Finally, our system’s 5.2x3.9” (131mm x 99mm) matte carbon fiber tips with stainless steel inlays eclipse the factory 4.6x3.46" (117x88mm) tips, giving the rear of the vehicle a sportier look.

RESONATOR

The resonator has been tuned to eliminate drone. Internally the system features two different size pipes. With valves open the exhaust travels through the larger and louder pipes. With the valves closed, it travels through the smaller and quieter pipes. In both cases unwanted sound frequencies (drone) is canceled out, and exhaust gasses travel uninterrupted through the system. No packing material is found within to alter the exhaust note.

BRACKETS

Our brackets ensure a strong and precise fit, every time. With our design, you’ll never need to worry about the brackets sagging and losing their shape over time, or the post slipping out of the hangers. The brackets are rigid, exact in their position, fit snugly in place and are made to stand the test of time.

TUBING AND WELDS

We use T304 stainless steel tubing throughout. We brush and de-burr all pipes, use mandrel bending techniques to ensure the pipes keep a constant diameter throughout, and use TIG welding for a strong and attractive weld.

TIPS

Our matte carbon fiber quad tips upgrade the rear of the vehicle dramatically. The motorsport-inspired tips tuck nicely into the factory valance, gently following the valance’s curves and demanding all the right attention in all the right places. We have a discreet APR logo onto the top of each tip, and we use T304 stainless Torca AccuSeal clamps that bolt on with ease with hardware that rotates out of sight. Lastly, since the tips are removable, you can upgrade to any one of our optional tip designs at any time.

CLAMPS & COMPATIBILITY

Our system uses OEM-style low-profile slip clamps and T304 stainless-steel Torca AccuSeal clamps for the exhaust tips. Our clamp selection allows the system to sit high in the exhaust tunnel, as is favored by lowered vehicles, with ultimate compatibility no matter what midpipe you may have. The clamps make for easy swapping of the exhaust tips, and slide out of the way to make adding or components. Each connection point is strategically placed to ensure the system has minimal opportunity to rotate during install or during years of heavy driving. Finally, because there are no flanges or swedges on the pipe, fitting the system to the factory midpipe or others is a breeze. There’s no cutting, welding, or glaring compatibility issues, and there are no gaskets to replace.


We’ve designed our system to be 100% bolt-on. There’s no cutting, welding, or finagling to get the system to fit. It simply bolts on thanks to the included reducer.
