APR MK5 R32 RSC Catback Exhaust System
APR MK7 / MK7.5 Golf R Catback Exhaust System (Valveless)| 06/25/2019
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 axel back portion of the exhaust has the mufflers and valves removed. Weight drops considerably and the system becomes more aggressive. With the factory DP in place, 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 to the APR Race DP, the system transforms and becomes unapologetically raw with maximum aggression

We’ve extensively calibrated the system to work flawlessly on the track, while retaining safety routines to protect your engine in the most demanding scenarios. This was all made possible by our engineering team's pursuit of perfection. Development vehicles were outfitted with additional sensors, including turbo shaft speed sensors, thermocouples, transducers, and more, along with our high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After thousands of hours of testing and tuning we created new calibrations that are fine tuned for several octanes and contain hundreds of map changes, with a vast array of safety features built in.
