Hi, I just purchased a new 2004 Mustang GT 40th anniversary convertible and am overall impressed but would still like to change a couple things. I big concern is anything that will void my warranty. I had a Bassani X-pipe on my 97' Cobra that sounded awesome. Is this a good choice for my GT or is there a better option? As well, I would eventually like to do some performance adders such as maybe larger intake, MSD ignition,ect. I am not trying to build a racer, just a sweet sounding stang with a little extra go. Thanx.
