APR Tuning S3 MK3 Catback Exhaust System
Vendor: APR Tuning
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. The straight-through brushed-finished mufflers smooth the exhaust note to a deep growl, without adding restrictions, while APR’s 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. APR’s cast valve housings enable the vehicle to be fitted with the factory electronic valve actuators, retaining OEM valve operation. Removable 4" polished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle. Optionally, this system can be configured without rear mufflers and valves at a reduced price point. Or you can add on APR’s exhaust remote system to allow for remote operation of your vehicle’s exhaust valve system.

Options / Add-Ons:
The APR Exhaust Remote lets you override the factory exhaust valve operation to fully open the exhaust valves at the press of a button. Simply plug-and-play and press “ON” to open the valves fully. To return to the original behavior, press “OFF” and the valves will operate as if the device wasn’t installed. This system works with both the factory exhaust and the APR Valved Catback Exhaust System.
