I've got a DOHC ZC in my CRX. DC 4-2-1 Headers, no cat (bought it that way) and Greddy something exhaust. Here's the deal, I'm a really anti-loud person, but I want the added power (3-5hp) of the header and "performance" muffler. What would be more effective in quieting down the motor and not sacrificing alot of power: 1) Install a catalytic converter; or 2) Put a more stock muffler on and leave the test pipe w/no cat. I know the cat increases back pressure which in turn raises compression a little, thought maybe just putting a stock muffler on would accomplish the same thing... or will it kill me? I dunno, that's why I'm posting... so there you have it... thanks.
