i need to install an exhaust system into my 2005 mustang gt, but i want a loud beautiful sound, what do u advise me to go for?
i need catback, hedders, and x or y pipe. (and if you can explain to me what is the difference between the x pipe ant the y pipe. it will be better thank you

 

y pipes are on v6's so u don't have to worry about that. You can either get a H or an X pipe. As for which sounds best ill leave that to someone who owns a v8 =D. You can check out some of the selection at http://www.americanmuscle.com/mustangexhaust.html and then listen to the sound clips of them at: www.mustangexhaust.com
