The Audi S5 Sport cat back exhaust is manufactured using only the highest grade T304 stainless steel materials available. CNC mandrel bent 2-1/2” tubing is used throughout the entire system for a smooth uninterrupted exhaust flow for added horsepower and torque. Hand fabricated mufflers incorporating B&B’s unique Purge Resonance Technology (PRT) give the S5 a distinct exhaust note. The simple in design yet unique in theory PRT mufflers allows for a deep sporty note on hard acceleration but offer a mild tone while cruising without the unwanted interior resonance.
By replacing the center muffler with a hand fabricated x-pipe we were able to give the S5 a little more exhaust note when tearing up the streets but still being able to maintain the lack of interior resonance at cruising speeds. To finish the system off B&B uses a quad tip design with 3.5” round double wall tips for a look that is pleasing to any enthusiast’s eye. With the system being an after cat design it is 50 state emissions legal and is backed by B&B’s limited LIFETIME WARRANTY.
