This site has a full setup: Ford Mustang Sound Pipe Delete Kit
I bought their roll bar setup and it is a very well made, quality piece
Long tubes are definitely on my mind, but I'm not sure about a catback unless the combination of hp increase and reduced weight pretty significant. On my gto catbacks only added around 5hp and were over $1000...stock system was over 70lbs tho. Is this a similar situation? It seems to be a pretty good performing factory exhaust, and it sounds amazing without the plates, ,not sure if I want to change that sound...
All in all, my concern is still about losing power with mods without a new tune...which defeats the purpose of my track key. I know its exhaust but do you think it will work directly with the track key tune??
