The APR 15-17 Audi S3 Sportback and T-Roc 8V Catback Exhaust System is a high-performance aftermarket upgrade designed to enhance vehicle sound, appearance, and overall exhaust flow. Crafted from hand-finished T304 stainless steel with TIG welding, this system features straight-through mufflers that produce a deep, aggressive growl without restricting exhaust gases. The inclusion of a Helmholtz resonator helps reduce unwanted frequencies, ensuring a refined sound profile. Strong, high-quality brackets and OEM-style clamps facilitate a straightforward installation process, providing a secure fit. The system also incorporates a cast 3-inch to quad 2.5-inch rear splitter for smooth exhaust gas transition and a tidy appearance from the rear. Removable 4-inch polished slash-cut tips add a motorsport-inspired aesthetic, completing the performance and style upgrade.

Designed for 2015-2017 Audi S3 Sportback and T-Roc 8V models, this catback exhaust system is compatible with vehicles equipped with factory electronic valve actuators, allowing OEM valve operation to be retained. It is a direct bolt-on replacement that enhances both daily driving and spirited driving experiences. The system is ideal for enthusiasts seeking improved sound, performance, and a refined look under the rear bumper. Installation is simplified with OEM-style clamps and high-quality brackets, making it suitable for both professional and DIY installation. This exhaust system provides a durable, performance-oriented upgrade tailored to the specific fitment of these models.

Overview

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.
