1993 Accord, my exhaust manifold is cracked and needs new exhaust system. I was looking at trying cat back from headers to the tip. complete system, Has anyone tried something like this and wondering if it has set up for the 02 sensor. I dont need anything loud . like my cars quite. Im sure it will help car breathe a bit better. Just want to make sure if anything I should worry about by doing this. Thanks for and advises.
