Got this as a gift for my son to fit into his Mustang GT. All I saw was a blurry shredding and ripping of wrapping paper in the driveway, followed by a manic jerk. Installation is easy, no cutting or welding, and the sound is awesome! I had a 1967 Mustang V8 in 1967. Newer cars are much better, especially with this exhaust. The way it crackles and talks as you approach the red line is amazing. However, if you want to be in silence, it works great.
