Bully Dog Performance
Exhaust System
Ford

The Bully Dog exhaust systems reduces backpressure and reduces exhaust gas temperature. However, they don't reduce either by too much. See, every Bully Dog exhaust is a balancing act, providing just the right amount of temperature and pressure to ensure that the engine works at peak performance without compromising fuel economy. That's why Bully Dog exhaust products are the premier diesel exhaust systems in the aftermarket today. Another reason is build quality.
