I have a 1991 Ford Mustang 5.0 Hatch. I am the original owner and it only has 88,000 miles on it. I drove it daily until the exhaust system went bad on it. Need advice on where to purchase a new exhaust system so I can have it put on. I want to stay with the original stainless steel pipes. Have been looking at the Magnaflow but don't know if this is the right choice. Can anyone help me?
