I recently bought a 1983 Civic S in AZ. I got the Copper historic vehicle plates and i am now exempt from emmissions tesing. WOOHOO!
So i need some help/advice...
-Is it legal for me to take off my catalytic converter from the exhuast?
-What kind of power gains can i expect if i do it?
-If i dont want to pay for a new exhuast system, is there a way for me to make the cat. conv. free flowing? like clear out whatever it is that makes it restrictlive?
-thanks for the help!!
