I went on a dyno before I installed test pipes, reminding me the glorious sound of the stock car. Soon I will dyno with the test pipes and share it as well. the garage walls really amplify the sound.
On a 85-90F day, it pulled 340-345whp ish
My first dyno a while ago had 355-360whp with 50-55F outside temperature.
either the car is getting old or it doesnt like warm weather. (both on dynojet)
