Do the high flow (green cat) smell as bad as a off road pipe?
I'm currently running lethal off road H on my DD and most days the smell is terrible. Thinking of going with the high flow cats or back to stock?
What's the pros and cons? Im thinking of going to it. What gains should I see? Other than bigger injectors and other hardware needed? Current set up is basic, lethal off road H, no resonators and a tune.
