Great exhaust sound. My only request is that he bring his own VS clamps to remove the factory ones on my old exhaust. Easy to install when raising the transom on ramps or stands. 13mm socket for removing the clamps and one of the rubber supports. Total time was about 2 hours and was very easy to align. you can tell when you turn it around for the first time. it makes me smile every day when i drive it. It makes a humming noise at 2000 rpm or when cruising between 75 and 80 mph, but it's worth it. My GT sounds like a GT should sound. Thank you very much. PS I wish they packaged them a little better because I had scuffs on the black part of the exhaust. But you won't see him because he's under the car. but I know they are.
