Does my '01 EX Coupe have two cats, one after the headers and then another behind the door? Why I ask is because I'm looking to put on a Skunk2 universal muffler on the end and am wondering do I need to get a resonator to smooth out the tone as I've heard of really ricey sound clips. Will the two cats accomplish this without a resonator? I don't have a silencer but it can more easily be added than a resonator.

Its one cat, with dual bricks, under the car.

So how does that compare to a resonator?

uh, they're 2 totally different things. A catalytic converter scrubs **** out for emissions purposes, and a resonator cancels out sound frequencies.

Uh, yeah I get the whole emission, save the environment, lets hold hands and sing concept but where do I need to put a resonator assuming that the two bricks (cats) will not tone down the exhaust. Simply put, will a resonator, if applied, smooth out the tone recognizably from the oem cat and if so where will it go. After the last brick and before the muffler? I'm trying to see if I really need a resonator with the two bricks.

what the hell is a brick. look man... you have ur engine...header..down pipe thats connected to ur cat converter. ur cat converter is for emissions..it cleans the air coming out the exhaust. it doesnt really tone down anything. after that you can put a resonator basically anywhere it fits. different positions after the cat and before actual muffler will produce a different tone but it still goes there. most likely if u buy a resonator..it will not just bolt up to the stock piping. this is pointless. if you get a muffler your car will be louder. why not just get a full catback and ull be fine. if your going to buy a resonator and a muffler then get the custom piping and be done with it. u dont need a resonator, but then again ull have just a fart can in the back... maybe some mufflers have a better sound but i highly doubt its the skunk2.

Ask boilermaker what a brick is. I had never heard of it either. When I look under there, it seems there are two cats and I'm just trying to get some suggestions about a resonator before I go to the muffler shop.

u shouldnt worry about whats under there now if ur going to the muffler shop. just tell them u want a muffler, a resonator, and custom piping and call it a day.

just buy a quiet catback system instead, you might actually save money if you put it on yourself, which is not that hard, and you won't be forced to drive around with civic that sounds like a very upset @$$hole.

A "brick" is slang for a "cat" which is slang for a catalytic converter. You've got three levels of translation to do there.

There is only one cat for all intents and purposes, but it has two bricks in it. Make sense? So after the "cat", where your 3-bolt midpipe bolts up, is where your resonator will go.
