Vivid Racing's VR575 Stage 2 horsepower kit for the 997TT takes are simple stage 1 kit and adds a high flow exhaust system.  The Agency Power exhaust system features 200cell high flow cats, 304 stainless steel construction, and a muffler design that will not drone in the cabin.  The VR575 kit includes our Softronic OBDII ECU Flash and a pair of Boost Recirculation Valves.  Softronic is the only tuning company that can flash your 997TT through the OBDII port and retain your warranty by providing your true original file and your tuned file.  At any point, you can load your original file back to your car and there will be no footprint that the car has been flashed.  In addition to the Softronic ECU Flash, we also include a pair of the Agency Power Boost Recirculation Valves.  The BRV's replace the diaphram system for a spring and piston design.  This helps boost come on stronger and hold more consistant to redline.  These install in place of the factory units.  The combination of these 3 products will give you the VR575 kit which you can further build on.  The ECU flash can be installed by yourself with the included cable.  Install time is about 1 hour.  The BRV's we recommend installation by experienced mechanics and these take about 2 hours for installation.  The exhaust system uses the factory style tips and saves over 30lbs.  This exhaust takes about 2-3 hours to install. 

Our test vehicle was run at the Palm Beach International Raceway on a hot and humid May day.  The car ran an 11.3sec 1/4mile trapping at 122.49mph.  If you have any questions about this kit, please contact us.
