SMS is proud to offer these Agency Power headers for the Porsche 996 and 997 Turbo vehicles.
“Agency Power has developed a selection of products that set the standards for Porsche turbo tuning. All new, the Agency Power Porsche 996TT | 997TT headers fit the 2001 and up turbo vehicles. Made from 321 Stainless Steel, the headers are complete polished. Flanges are laser cut for a precision fit. Each header features a highly engineered collector to keep your turbo spooling faster than stock while creating additional horsepower and torque. Tested on a 2001 996TT with factory K16 turbos, these headers added almost 10 wheel horsepower. As tested on a 997TT, the headers gained almost 20 ft/lbs of torque. In addition to improving performance, the headers also change the tone of your vehicle. Adding a deeper sound and making the turbo whistle more audible. Headers will fit the standard 996TT model or the X50/Turbo S model using the K24 turbos. They are also a direct fit to the 997TT.”
