CTS TURBO B8 S4 CATBACK

The CTS Turbo B8 S4 Catback is a complete exhaust solution engineered specifically for 2010-2016 Audi S4 B8 and B8.5 platform vehicles. Precision-mandrel bent tubing maintains consistent internal diameter throughout, reducing backpressure while improving exhaust flow efficiency. This direct bolt-on system replaces the factory catback section from the catalytic converters rearward, delivering a deeper, more purposeful exhaust note without drone. Constructed from high-grade materials with TIG-welded joints, it's designed for professional workshop fitment and long-term durability in demanding performance applications.
