Product Information

APR Catback Exhaust System For Audi S3 Sedan

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 mufflers smooth the exhaust note to a deep growl, without adding 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. Our cast valve housings enable the vehicle to be fitted with the factory electronic valve actuators, retaining OEM valve operation.  Finally, removable 4" polished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle.

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.

 

Mufflers and Resonators

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.

 

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.

 

Created In-House

Our exhaust systems are proudly designed, developed, assembled and quality controlled in-house at the APR 78,000 sq.ft performance campus in Opelika, Alabama.
