I'm eventually going to change my DP. I live in Maryland. I know all about emissions, etc.
Since high flow catalytic converters are not legal, then what the hell is the different between it and going catless? What, for the fact it has "something"? If a catless MD vehicle passes via ECU, then why spend the extra boat-load of $ on a high flow cat?
IDK, just doesn't make sense to me.
