That's all provided I understand your original question right?
Thanks Rob and everyone else, yeah I considered the noise levels as well although as long as you don’t go heavy on the right foot with authorities around then there’s not much of a problem.
About the power, I read about Cummins engines performing better with a straight pipe on another forum so I thought I’d ask here if anyone has done it with their KDs and what are the pros and cons. Are there any reasons why Cummins-powered Dodges would do better with a straight pipe?
Thanks in advance everyone!
