I have a 2005 dodge dakota with a 4.7 liter magnum, 4 wheel drive, locking differential, 40,000 miles, and an SLT package. But i was looking for something to do to my exhaust. And when i took a look around i noticed that there were 3, count em, 3 resonators under there. I looked more carefully and saw that it could unbolt into three sections. If i took the last two sections off still leaving one small resonator and exit the exhaust pipe out the back will that void the warranty i still have on my truck? the cats are still there and it shouldn't do anything about emissions. Will this cause problems in the engine with the fuel mixture? And any back pressure issues? let me know because i would not like to void my warranty. (and they can be put back on)
Usually anything infront of the last O2 sensor you cannot mess with it will void your warrenty. Due to all the smog rules and regulations. To be on the safe side I would call a Dodge dealer and ask them what you are able to do to the exhaust without voiding your warrenty.
