I am going to be purchasing a Flowmaster cat-back for my 1991 Mustang LX 5.0 Vert in about 3 weeks (not that the time frame matters but oh well
). Here is my situation: I want my car to be LOUD on the outside, but quiet when I need it to be. I can't afford to get tickets from the cops or my dad says I have to sell my car (so he thinks
). I also want to be able to hear my radio without blasting it and be able to have a conversation in my car while driving. Which catback would be best for me? Also can I install it myself or should I have it professionally installed?
