B&B Mustang 2005+ Axle Back Exhaust.

As a direct fit, this Billy Boat Performance Exhaust hand built system is designed to increase horsepower, and torque. The 3” mufflers are a straight through design that finish off with a bold 4” double wall round tip. The exhaust tone at cruising speed will provide a rich exhaust note. When you go wide open on the throttle the sound will continue to improve and becomes a bold muscle car sound.

Each Billy Boat Performance Exhaust is custom-tuned to match its application for the best sound quality and performance combination. Our mufflers are designed to cancel out annoying interior resonance while providing maximum flow and performance. All B&B products are backed by a factory-written limited lifetime warranty!
