I'm looking for direct bolt on stock muffler choices for my 92 Hatch. I want to have a stock muffler but I would like to have one that flows more air than the current CX muffler. I had a DC4 integra and I was able to bolt on a Type R muffler which gave it a lot more air flow but because it was a stock muffler, I didn't have any trouble from cops. I'm looking to do the same for my Civic. Any suggestions? Thanks in advance for the help.
