Tuning in a state without emissions

JSur · 07-19-2016, 02:35 PM

To my understanding without emissions I'm able to make the A/F ratio a little richer, which is what causes a car to fail the carbon test no? I was thinking of getting test pipes bit I'm really satisfied with the sound of my car and I'm afraid test pipes will give me more of a raspy sound. Also, somebody mentioned that the back pressure provided by hfc vs test pipes are more beneficial with boost. I'm not too sold on that though

Turbos and backpressure do not like each other.
