i have a 93 civic with a stock b20 (advanced timing) with DC headers and stock exhaust...the car has no cat. it is extremely loud and winny...what can i do to make it quiet??? different muffler??? put a cat. on it???
 
Putting on a cat will quite it down but if you want the performance of having no cat and an exhaust try to find a different muffler. Apexi world sport 2's are real quite and many parts store mufflers can be welded up (magnaflo, flowmaster, turbo muffler, ect). These give a throatier sound. The biggest thing to remember is its a honda, its not a torque monster v8 that redlines at 5k rpms, and because of this you will never get that sound. Learn to love the sound of 8k rpms;)
 
Contrary to what the above posters have said, a cat is not going to have much affect on the sound/tone of your exhaust. Catalytic converters aren't designed to muffle, they're designed to (more or less) filter your exhaust. If you want a deeper tone, look into getting a bigger muffler. If you have a tiny-ass fart can it's going to be loud, high pitched, and raspy, and if you have a gigantic fart can it's going to be loud, low, and generally shitty sounding. Long story short, stay away from fart cans. Your best bet for a low, non-ricey sounding tone would be to either A. buy something along the lines of a Thermal or RS*R exhaust (with an inline muffler, not a can-style), or build your own exhaust with an inline resonator or 2 and something like a dynomax or ES Oval muffler.
