Cat-back .01 starEasy intall. Great soundApril 6 08 Silverado 1500 6.0LInstalled with stock manifolds and was way too quiet for my liking with the muffler. Cut and welded some 3 inch exhaust piping to replace the muffler and sounded amazing. Getting ready for a dyno run I installed a set of Kooks headers and y pipes to this exhaust and was way too loud for my liking without the muffler. I reccomend either deleting the muffler with this kit of wanting to use stock manifolds or either adding a good set of headers and using the muffler TravisS6 jegs.com
