ok so basically ive been doing it in stages first obviously i had the factory exhaust on there then i bought the 4'' ss mbrp exhaust which was a mindblowing upgrade (as obs owners know factory exhaust=no turbo noise) and for the longest time i thought about straight piping it and after researching it on here for a while i found out that all 7.3 owners can do it with NO loss of power b/c our turbos are fixed pedistals and that turbo creates so much back pressure that it could in theory only need a downpipe. but everyone else mainly the 6.0 owners have variable vain turbos which run completely diff and need a certain amount of bp to not lose hp and performance. so one day i was curious so i took off the muffler and back . let me tell you it was the most bad *ss raw sound ive heard in my life but unfortunatley i had to put it back bc my dad said the exhaust gasses can cuirculate under the truck and could kill you idk stupid so eventually (now) i got a delete and put it on on monday and its just like i remember im a high schooler and let me tell you drivin down falcon pass every single kid stops and stares! i get thumbs up, and some cover their ears
haha so to all obs owners straight piping ur truck is very easy, truck is more responsive, and besides a chip is one of the most "cant take the grin off your face" upgrades!
sorry for the long read i just had to tell yall
