The Remus axle-back exhaust for the 2013 Audi S3 Sedan Quattro 2.0L (CJXc) is a rear-section exhaust intended to replace the stock axle-back portion; tail pipes are required. It is built to match the S3 Sedan’s exhaust routing and mounting geometry, allowing Remus components to connect with the existing midpipe and underbody attachments for correct alignment and installation on that specific 2013 S3 configuration.
