Just wondering what kind of warranty safe mods are out there, besides cool air intake ordered a S&B. Would like to do some exhaust work but I'm dealing with a 2011 LML so it has DPF and all that bull. I also saw a jet performance mass air flow sensor. Looking to get a little more out of the truck with ought voiding anything I know it's hard to do but that's the way I have to go.
Thanks
