APR | Catback Exhaust System - RS3 2.5T 2025

APR – Catback Exhaust System RS3 8Y

Description

The APR Catback Exhaust System (CBK0053) is designed for the Audi RS3 Sedan (8Y) equipped with the 2.5T engine. Hand-crafted from brushed T304 stainless steel with full TIG welding throughout, it delivers both exceptional build quality and performance. The dual 63.5mm mandrel-bent tubing provides an ultra-smooth exhaust path feeding into quad 63.5mm outlets, neatly exiting through the factory RS bumper-integrated exhaust tips. The brushed sound-absorption mufflers produce a deep growl without restrictions or rasp. Cast valve housings retain the factory electronic valve actuators for variable OEM sound levels. Strong mounting brackets and OEM-style slip clamps make installation and removal straightforward. Low-profile design, suitable for lowered vehicles. Bolt-on installation.
