Upgrading to a 2-into-1 or a slip-on exhaust system can significantly improve the Fat Bob's power delivery and, of course, the sound. The roar of a high-performance exhaust is a treat for the ears and a signal to everyone that your bike means business. Performance exhaust systems are typically made from high-quality materials like stainless steel, which adds durability and a sleek look. When combined with an upgraded air intake, the exhaust system contributes significantly to the overall horsepower and torque gains of the Stage 2 upgrade.

• Camshaft Upgrade (Optional): While not always included, a camshaft upgrade can further enhance the performance of your Fat Bob, especially if you're aiming for maximum gains. The camshaft controls the timing of the engine's valves, which determines when the intake and exhaust valves open and close. A performance camshaft is designed to optimize this timing, allowing the engine to breathe more effectively and produce more power. The camshaft upgrade offers an extra level of performance. It is important to note that the camshaft upgrade requires a more complex installation and may increase the overall cost of the Stage 2 upgrade. However, the gains in horsepower and torque are well worth it for those looking for the ultimate performance.
