i still have the header back exh for an EF hatch or CRX i want $45 for it. it has the flange to bolt up to the header, and also has the hangers on it so it will hook up to all the oem mounts. it also has an O2 sensor in it too!
it comes out of the back at an angle, and it looks pretty good on the car! i had it on my rex for a while until i just got my new exh for it.
i also have some universal mufflers and exh too. i guess $25 obo on each of them
here's some pics of em all.
