Hi guys I'm new to tuning and I bought a used 03 rsx. It had/has a Megan Racing exhaust and I got a fix it ticket with it. I've already gotten the ticket signed off but I was wondering how I could reduce the noise or silence it? To prevent another ticket again. To be honest I might go to stock too because this exhaust messes with the O2 sensor and gives me a CEL occasionally.

So anyway what are your two cents on this? Thanks in advance.

If it has the option to have a silencer put in, you could look into getting one.

If not, you'll need another exhaust.



As for CEL, does it have a defouler on the o2 sensor? If so, try two. Mine needed two of them to make it stop bitching.

How can I check if it has an option for a silencer? Screw on the side or something I think?

Look at the muffler tip, if it has holes in it, those are for the screws that hold the silencer in there so it's a step in the easier direction.





As for the o2, look at your exhaust around the header/cat connection
If the sensor doesn't look like this, you'll need a defouler



Go to a store and get this



Will have to bore them out so you can screw the o2 sensor into one, then screw that into the other defouler, then screw that into the exhaust
