I'm replacing the exhaust on my 89 CRX. The current system is a custom 2" or 2 1/4" setup with a flow pro muffler and a huge ass tip. I'll confirm the size and get some pics when I get if off tomorrow. There's nothing wrong with it, I just want something bigger for my new setup. It doesn't sound that bad either. It's a complete setup including the cat, so it should be a direct bolt on. $60
