Before we headed off to the Gumball 3000 rally, we did 1 more mod to our Project Porsche 997 Turbo and installed these Agency Power High Flow Headers. The headers feature thick flanges with 304 stainless steel tube that is TIG welded. Each tube is designed to come into the collector for the best exhaust flow possible. Having run the **** out of this car for 2000 miles in 6 days, the headers truly made a difference. Here are a couple pics from the install.

Stay tuned to our Project Porsche 997TT section as next week we will be installing GMG sway bars and a IPD intake plenum with dyno tests.

Noticeable difference in turbo spool, low end power... but the best bang for the buck is the ECU flash guaranteed.
