I talked to a buddy today..I said my cat was bad..He suggested a used cat..I said I was gonna get a high flow cat besides its new...He asked will I have issues going thru emissions..I said I shouldn't..Jan 2018 I'm getting historic tags since my car will be 20 years....I'm in Md...... I just found out starting October 1 you cannot have historic tags and drive to work,school etc....
So now reason I'm asking is would I still be able to pass md emission with a high flow cat and would the "Police" Hands Up give me problems having a high flow cat.....
Thanks...Any advice appreciated.......
