The Billy Boat Catback Exhuast is one of the best performance modifications you can make on the B8 Audi A5.

With the Billy Boat Catback Exhaust, you will see performance gains of 18hp and 20lb/ft torque. Unlike most aftermarket performance exhaust systems, the Billy Boat Catback Exhaust for B8 A5 was specially engineered to provide a sporty, more aggressive exhaust tone without having a heavy exhaust drone to help maintain driving comfort. The Billy Boat Catback Exhaust is a complete bolt-on product, so no custom welding, cutting, or fabrication is needed for installation.
