I bought a 2 owner 31K 5 spd v6 mustang recently. I want to convert it to dual exhaust. But, the only true cat back dual exhaust conversion that I can find other than the system from pypes is the flowmaster force 2. I personally like flowmaster products and I had a flowmaster American thunder on my 86gt. But I don't know anything about thier force 2 system. Has anyone here ever used one? And if you have what do you think of it?
