Hey guys kinda new to the whole diesel thing. I've got a 2008 Ram 6.7. No deletes but I've got AFe blade runner air intake and intercooler tubes and a bulldog tuner. My question is this. I want to get a 5" exhaust. Performance wise what are the differences between the dog back and the turbo back exhaust? I'd really like to keep it all legal. And then what would be a the best 5" exhaust I could get for it?
