As you all know I have an 07 mega with the 6.7. The truck is payed off and is still under warranty. Would adding stacks void the warranty? I was told cat back systems do not void warranty. Isn't stacks just a type of cat back system? I'm not removing the cat or punching threw it. I dont want something to go wrong in the future and have the dealer deny warranty work because of the stack mod.

since you are not removing any emissions related equipment I would say no. but that wont stop them from looking harder through the ECM to find any traces of performance mods.
Will drilling a huge hole in the bed void any possible warranties? I just dont want to give the dealership any ammo to void any warranties. This is my first "NEW" truck so the warranty stuff is new to me.
