Well packaged and packed to protect the ends from damage.The system fit well with little adjustments made. It sounds and looks great. Gibson and Auto Anything make good partners, thanks.

Easy install, except had to trim first mount right behind muffler on passenger side. Sounds awesome.. getting louder as it breaks in... small gain in fuel economy, about 2-3 mile a gallon... big increase in low end torgue and high end H.P., ALL AROUND BEST EXHAUST I EVER HAD, WILL RECOMMEND!!!!
