Part 4 of 6. Just installed a NXTSTEP axelback exhaust on my 2014 Mustang GT. http://nxtstepperformance.com/index.php The worst part of the install was removing the stock mufflers. After the stock cans were off, i could remove the hangar brackets and install them on the NXTSTEP muffler hangars and then bolt the hangars to the subframe with the new cans mounted to the hangars, only needing to push on the rear hangar rubber grommet on the muffler. WD-40 helps with both the removal of the stock cans, and the install of the NXT's. I removed the stock clamps from the stock mufflers by bending them back an forth until the clamp ties broke off (necessary). I got interrupted by rain during removal and install, but if i did it all at once, i'd say it should only take you an hour to remove the stockers and install the NXTSTEP cans, if you are mechanically inclined and have a jack and stands and tools.
