I just purchased a 2005 Mustang GT and I want to upgrade the exhaust from stock to LOUD! Do I have to get the computer tuned...what if I use electric cutouts, will cutouts hurt my stang without tuning? Also, does adding an aftermarket intake require any tuning?

 

i would tune it once you do the exhaust and the intake.

 

I know tuning will give me better performance, but will NOT tuning mess up my cars computer...I don't want to send my car into limp mode and have my warning lights coming on because I have a good sounding exhaust or cutouts just to be loud
