haha, exactly what me and my dad did, jacked the entire car up, put some jack stands under there and had to cut off the old pipe... installation went smoothly, took about the same time as pony joe, considerign ym dad had already put an identicle kit on my brothers mustang a few years earlier (which he had long sold by then)
Simple install, it cost 300 including the shipping and the brackets, and i swear that it is the best sounding exhaust on our 6es, everyone says 'oh you wont get GT sound' i have a friend with an 00' GT, and he admits my car sounds much better than his, lol
