Which of these 2 exhaust setups will give me lower EGT's?
I have already done a search on the forum and could not find a clear answer. Some say "the longer the pipe, the lower the EGT's," and some say "the shorter the pipe, the lower the EGT's."
My tuck is mechanically bone stock except for an airaid filter, zoodad, CCV mod, and straight piped-stock exhaust with a 5" tip.
After straight piping the truck I noticed quicker spool-up and the sound was amazing. I am very satisfied with it. But, I just recently received a chrome 5" stack for free. I was thinking about possibly getting rid of the rear half of my exhaust and running the stack "dumped" after the cab. The stack has a 45degree angle on top so that would be my turn-down. Basically, I would be increasing the pipe diameter to 5" after the downpipe and shortening the length of pipe.
Do I have anything to gain from this other than possibly sound? Lower EGT's? MPG difference?
Would it affect the 6.0 exhaust back pressure sensor?
