OK, guys how long did it take your cars to have better response?
At WOT the power is incredible, quite different than the stock exhaust and the sound is excellent.
Installation, more trouble taking the stock cats out but after that everything went reall smooth. Only mod I might do is add a washer on the rear hanger. Tips are to close to the rear valence.

Tony, thanks for the excellent system. Keep up the good work and quality.

Hay got a question for you. Where exactly did you have to add the washer. Did you add the washer to where the mount bolts to the bottom of the car?
