B&B Sport Turboback Exhaust SystemAudi A3 FWD 2.0T 05-09

This Sport version of the turbo back exhaust for the 05-09 Audi A3 2.0T FWD offers the same deep robust tone as the stealth but with a more assertive note. The Purge Resonance Technology or PRT design mufflers offer the latest in resonance control technology from B&B. Completely redesigned and reengineered, the system is simple in design, though more complex in theory. It allows true straight through exhaust passage under aggressive driving conditions, though a mellow sound is emitted at cruising speeds thanks to the unique Purge Chamber.

3" CNC mandrel bent tubing is used throughout the entire system for a smooth uninterrupted exhaust flow. With a 200 cell high flow metal catalyst in the down pipe you will see reduced turbo lag, quicker spool up and increases in both horsepower and torque. For aesthetics B&B choose their twin 3" round double wall tips for a bold yet distinguishing look. Mounting in the factory mounts make installation of this system a breeze and like all B&B exhaust systems it is backed with their limited LIFETIME warranty.

Each Billy Boat Performance Exhaust system incorporates 3 generations of fabrication skill and racing talent. Every system starts with T-304 stainless steel, known throughout the industry as the highest quality material practical for after-cat exhaust applications. All exhaust tubing is mandrel bent on sophisticated CNC machinery for a precise fit and uninterrupted exhaust flow. The use of T-304 stainless steel flanges also offers high strength and complete resistance to harsh elements. All hangers, resonators, and tips are T-304 stainless steel as well. Billy Boat Performance Exhaust mufflers are crafted in-house with years of racing and street development invested into the design. Each muffler is tuned to match its application for the best possible performance gain and sound quality combination. For strength, the muffler end-plates are radiused at the inlet and outlet preventing premature cracking. Additionally, reinforcing gussets are used when necessary. Depending on the application, you can choose from 3 inch round tips with a rolled edge, 4.5 inch oval rolled edge tips, 5.25 inch oval rolled edge tips or DTM style tips for European applications.
