2002 Honda Civic SI back to stock
in a year
I just bought a 2002 Honda Civic SI. And it was owned by a guy that lived in a county that doesn't do smog checks. So of course it had a full DC Sports race header with no catalytic converter. But living in a normal county where smog is an annual process, I had to peice together a semi normal exhaust to pass smog. This gasket fit perfect on an aftermarket header to a stock catalytic converter. It seemed over size at first. There was not a super tight fit. But after driving for a few months, I can say it seals fine. And it is a flex joint. So some play is ok. And after inspection, before install, it can fit the stock 2.2" header flange or 2.5" larger flange & still seal well. It worked out great.
