This cat-back exhaust system is a direct bolt-on replacement for the factory system and is precision crafted using 100% T304 stainless steel, proprietary Purge Resonance Technology (or PRT design mufflers), and 2.5” CNC mandrel bent tubing provided for a smooth uninterrupted exhaust flow.
PRT, which is the latest in resonance control technology from Billy Boat allows for a straight through muffler design with a deep sporty note on hard acceleration, while the purge chambers collect and cancel the unwanted resonance at cruising speeds with a nice mild touring tone and no interior resonance. Besides the improved sound the Billy Boat system will also increase both horsepower and torque. For aesthetics, B&B choose their twin 3” round double wall tips for a bold yet distinguishing look. Like all their products B&B stands behind the A4 system with their limited LIFETIME warranty.
Now that you’ve freed the air flow exiting your engine, why not enhance the flow entering it. Cold Air Intakes allow your engine to access cold air, which increases performance, giving you more horsepower when you go for the loud pedal.
