They can be ordered with 200 cell catalytic converters or as cat bypass "RACE" pipes (no cats). Race versions are for off road/track use only. By combining the exhaust pulses from both sides of the Porsche boxer motor with an "X" at the center of the muffler, we have created a scavenge effect to help speed the flow of gases, as well as, developed a unique, exotic sound that has to be heard to be appreciated. Our trademark sound is well known and highly respected throughout the industry. Approx. 6 lbs. weight savings and 10HP improvement over OEM. Our choice and highly recommended for the 997.
