Are you looking for the best exhaust on the market for the 998 turbo? Look no further! This BMP Full Velocity muffler gains a massive 20-25 horsepower due to the unique internal design. After spending many hours on our state of the art Superflow 902 dyno, we developed a recipe that will blow the competition away. This Full Velocity has an excellent sound at all RPM, and is very quiet for a straight through exhaust. This muffler bolts up right to the turbo and is made of 100% stainless steel. It's lightweight and fits perfectly into the chassis. Available in bare stainless, or ceramic coated to help hold more heat into the exhaust.
