First off, you're probably better posting this in the Tow Vehicle forum. Second, there =are= things you can do and not void the warranty. One you =used= to be able to do was to "chip" or reprogram the ECU with a handheld computer; don't know what's doable these days, though. You store the stock data, enter the new data then, if you need to go in for service, you swap the performance data with the stock. Same if you have emissions testing. Stuff like a cat-back exhaust should be no problem at all.

I have been told by a mechanic I trust that on the 2011 and newer trucks the dealers can tell if you reprogram and then program the factory settings again before taking into the dealership. He said it's a sure way to void your warranty.

Be careful!
