With all the mustang experts out here that are at our disposal I was just like an honest answer. I don't have lots of money but I know that the stock muffler is just to quiet. I'm spending more money on gas just so I can hear it. So I want a muffler that is louder yet not weaker on performance. This doesn't mean more , it just means the same. I love the Mac exhaust system. They are tucked away neatly underneath and are casted in shiney chrome metal. If someone would answer my millon dollar question than great if not I am going to order them anyway. The slp I think will hurt in the performance area considering they are just running straight out the back. But as I said before I'm not the expert. Hell the slps' are cheaper thats for sure.
