  • Looking for the most powerful Axys pipe on the market? Here it is! We took our time to develop this pipe and make the most horsepower possible. Gain 10-11 peak horsepower and great mid range power. When drag racing a stock machine, this pipe blew away the competition! Best thing is, this pipe is a work horse. Many pipe's peak power falls off when the engine becomes heat soaked. This one keeps bringing the power no matter how much we tortured it on the dyno or in the field. Nicely finished in ceramic chrome to build heat in the pipe and keep under hood temps down. No EFI controller required, but is highly recommended. We pick up 2-3 peak horsepower and excellent mid range with the Bully Dog GT. It also has many added benefits and map fixes. This pipe fits right into your stock muffler, or a BMP lightweight muffler.
