Ok, a little help would be nice.
First of all, what is CAI?
Next, why would the warranty be void? Couldn't you just set the programmer to go back to stock and put the stock exhaust back on? I know it would be a pain in the arse to change the exhaust, but it would get you back to stock.
I don't want to screw up my warranty but I would like to remove the DPF and get a nice exhaust note. Is this just not possible if I want my warranty?
