First off your post is in the completely wrong section... This is the guns section :roflmao:
2nd if I am not mistaken it is just a straight pipe exhaust system and a tuner to delete all the def bs... Then you would just remove the tank and all that goes with it... Not 100% cummins knowledge but that's how the dmax is!
To my knowledge H&S makes some type of chip/tuner that you have to send your ecm to them and its only like 25 horse or some bs and it cost a arm and a leg. You really cant do jack crap to a 13 cummalong at this time.
Tell him to trade it in on a duramax. :thumb:
edit- bully dog makes the chip. You cannot delete the def yet. To my knowledge.
Thanks guys. He just wants to get rid of the restrictions. He didn't think there was too much for it yet. I just figured I would run it by everyone. Sorry about the wrong thread.
