I looked underneath my new truck today and noticed that the entire exhaust system is welded together. No "Off-Road" only pipe is going to replace the DPF easily...Originally Posted by More Power
Like you said electronics will most likely prevent it, but with programs that re-write ECM/PCM code, that can always be changed too...
Since the DPF should have a life expectancy of 200k miles give or take, cutting it off, cleaning and rewelding wouldn't be that big of a deal. By then, if this motor is truly like the LBZ I can see replacing the exhaust system, repgramming the computer, etc... By law, you can't tamper/modify a working, under warranty exhaust system and I doubt the DPF has a 200k warranty...
BTW, the selling dealer made me sign a "I won't tamper/remove emmission components from the Truck paperwork..."
