Yesterday my exhaust pipes decided to break underneath the truck right after the two cats and h-pipe. Needless to say I simply cut them off and left the pipes running under the cab. Do i need to at least put turn downs on the pipes? I am refusing to rerun the pipes out the back like normal. I did notice a difference in engine temp today during usual driving conditions and very big difference in sound. What do you guys think? My idea was to cut the two tips off my old exhaust and put an angled pipe at a 45degree angle with the tips attached to it?
