2008 6.7 Waranty
 

I have 32000 miles on my truck with extended bumper to bumper coverage to 2014 or 62000 looking for better fuel milage i am researching a 4 inch flow pro turbo back with miffler,EGR vale /cooler delete with a smarty jr me programer what will it do to my waranty ? How much fuel millage gain keeping foot out of it ?

the way i look at it is....if you MOD a part of your truck just assume u are voiding the warrenty. when u delete all the emissions equipment you run a risk of them refusing to cover under warrenty. i wouldnt do it..... especially because u paid all that money for the extended warrenty. maybe just do a dpf back exhaust....cold air intake.... and a dpf friendly tune till the warrenty is up... jmo

hey your just up the road from me im working in LaPlace LA. dont even wast the money on dpf back thats about a joke i would do a delete pipe (so its ez to turn back stock if needed) block the egr leeaving it all bolted in place just incase all you will have to do is pull the block off out of the crossover tube and get a good tuner jmo some dealers are cool about it though my dealer in oklahoma recomended me to remove i told them thats nice cause i just turned it back stock last night they said next time leave it all on just bring it here :tu:

its not too bad to unbolt the deletes if you need to go back to stock if you are going to spend the $$ just delete away and dont cut or wreck anything when you are taking it all apart. it takes about an hour and a half to r&r the whole exhaust and probly another hour and a half to pull the egr crap out.. but it does suck when oyu know you gotta put it back to stock but its worth it for the milage and just keeping the crap outta your motor... and it will sound like a diesel!
