In true Billy Boat Performance Exhaust fashion, B&B has expanded their already large Audi line with the addition of a newly designed system for the all new Audi S5. Manufactured using only the highest grade T304 stainless steel materials available the full 2-1/2” system is a direct replacement for the restrictive factory system providing increases in both horsepower and torque. Hand fabricated mufflers incorporating B&B’s unique Purge Resonance Technology (PRT) give the S5 a distinct exhaust note that is louder than the stock yet pleasing to the ear. Billy Boat Performance Exhaust offers a touring system or a sport version that replaces the center resonator with a hand fabricated x-pipe for the owner that is looking for a louder, more aggressive note. To finish the system off B&B uses a quad tip design using 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.
