Clamps provided were the wrong size. I had to go to the hardware
Easy to install. Flowmaster sent the wrong size clamps . I had to go buy the correct size ones. Sound is good bit there is a very annoying exhaust drone 1600-1800 rpm basically 72-75 mph highway cruising. I would think it would get annoying on a long trip. Not as loud as I would have imagined, glad I got this and not the moderate series.
