I would like to install long tubes however i am still under warranty. Actually i only have 2900 miles on the truck.... If i do long tubes then in order for me to switch it back for warranty work i must change the whole exhaust. With the short tubes i can just unbolt them and put the maniflolds back on. I am just wondering if the gains on the short tubes with my new 6.0 will make them worth keeping or if i should just sell them.
