Ok, finished the install a few minutes ago of my HFC, 18" res, cat-back exhaust. All I can say is WOW that is music to my ears. Took it for a test drive and seems the ECU has to relearn as large throttle lag in the begining but as I drove on it started to improve. 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.
