Ok,I'm lookin at the website you gave me,but I guess the next question would be,which exhaust is better?I realize there is many to choose from,and it all depends on what I would like,but I have no Idea where to start!Just to more or less know what I'm looking for,I want my Mustang to sound really tough! I almost want it to sound tougher than what it really is(LOL!)! If that makes any sence!?Anyway,I'm gonna keep lookin and maybe after diggin around I'll find something. I guess the real reason I'm asking for help is because I'm alittle outdated! I thought "Flowmaster"was still in,and I guess it's not!(Out w/the old,and in w/the new!). Also,do I need to do any other Mods to my car with this new exhaust?Other than a new K&N?
