APR VW Mk7.5 Golf ‘R’ Valveless Cat-back Exhaust System (Louder) – CBK0020

The APR Catback Exhaust System personalizes your vehicle’s looks, sound and performance. Beautifully hand-crafted T304-stainless-steel components adorn the system with stunning TIG-welding throughout. Our straight-through brushed-finished stainless-steel piping give the exhaust note an aggressive growl without any restrictions, while our Helmholtz resonator reduces unwanted frequencies. Strong high-quality bracketry and OEM-style clamps hold the system steadily in place, making the install or removal a snap, and fitment simple, yet precise. A cast 3″ to quad 2.5″ rear splitter creates an ultra-smooth transition, steadily feeding exhaust gasses out of the system, while looking tidy from under the rear bumper. Lastly removable 4″ polished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle.For the more track minded enthusiasts where weight, sound and price point all are highly desired metrics, the APR Valveless system is the desired configuration. In this configuration the axle back portion of the exhaust has the mufflers and valves removed. Weight drops considerably and the system becomes more aggressive. The system is louder and more aggressive, but thanks to the center Helmholtz chamber, drone is reduced, giving a more pleasant, yet aggressive driving experience. However, when upgrading other exhaust components, the system transforms and becomes unapologetically raw with maximum aggression – A true track enthusiast’s dream.

Product Information

System Overview

Our exhaust system uses larger piping compared to the factory exhaust system, yet weighs the same. We use 3″ OD piping, which then splits to a quad 2.5″ design. The factory system uses 2.57″ piping before the resonator and 2.78” thereafter. Finally, our system’s 4″ exhaust tips dwarf the factory oval tips, giving the rear of the vehicle a sportier look. The diagram below shows the system with rear mufflers and valves, which can optionally be removed.

Rear Mufflers With Valves

The rear mufflers are responsible for reducing the exhaust note and do so without adding unnecessary restrictions to the system. Each unit features two straight-through perforated tubes that are tightly wrapped with stainless steel and fiberglass material. With the valves closed, the system is tamer, but once opened, the system sounds deep, throaty and aggressive! The mufflers have a beautiful brushed finish, and are tucked high in the exhaust tunnel, making them perfect for lowered vehicles and a treat to see when looking at the vehicle from the rear.

Rear Section without Mufflers or Valves

For the more track minded enthusiasts where weight, sound and price point all are highly desired metrics, the APR Valveless system is available. In this configuration the axle back portion of the exhaust has the mufflers and valves removed. Weight drops considerably and the system becomes more aggressive. The system is louder and more aggressive, but thanks to the center Helmholtz chamber, drone is reduced, giving a more pleasant, yet aggressive driving experience. However, when upgrading other exhaust components, the system transforms and becomes unapologetically raw with maximum aggression – A true track enthusiast’s dream.

Front Helmholtz Resonator

The front resonator is responsible for eliminating unwanted sound frequencies from the cabin. This is done without introducing added restrictions to the system. Using Helmholtz technology, sound waves bounce through the chamber and back into the exhaust stream, eliminating the undesirable frequencies to make the exhaust note more pleasing. During cruise, with the valves closed, the system remains calm.

Cast Quad Splitter

We cast the axle-back splitter to maximize the system’s performance by keeping exhaust velocity high and back pressure low. This is accomplished by gradually splitting the system from a single 3” pipe to quad 2.5” pipes. The organically shaped casting allows us to make this transition gradually as to not disturb the flow of gasses. Furthermore, as this component is visible from the rear of the vehicle, we made sure form matched function with a beautiful surface finish, TIG welding, unique bracketry and brushed, mandrel bent tubing.

Exhaust Valves

Our system features two valves that allow control of the volume of the system via the factory exhaust valve actuators. In doing so, the system can go from tame to aggressive instantly! Unlike pneumatic systems, and other common valves found in the market today, our system maintains identical OEM operation all the way down to the factory valve actuation angles. Furthermore, the system is fully compatible with exhaust remotes, allowing end users to manually open the system at the click of a button. We cast the valve housings out of T304 stainless-steel. Internally the system uses CNC-machined T303 components and brass bushings, which have stood up to our extreme torture testing. All necessary hardware is welded into place and is designed to combat heat and vibration for years to come.
