CatBack Exhaust?

[HuGo]

Ok, today is the first time i literally looked at how my muffler/exhaust was put on. Well whats the difference between exhaust and muffler or is it just the way you want to call it? Anyway, first time after like 2 years that i see actually see it. The welding looks like sh!t. But i want to know if what i have is considered a cat back exhaust or not? If NOT, what makes it a catback exhaust.

DustenT says, "exhaust does NOTHING for performance unless you are running forced induction."

Well how is it that it does nothing for you stock but it helps when you have FI? What is the difference that you either have it for sound or have it go with forced induction? Please guys, dont be mad, im learning. I could later explain other people that dont know too. Its all a chain guys. Be patient with me

Dude, a cat-back is just that! It is a replacement of the Silencer and Muffler from the catylitic converter back. The cat.(short) is what helps the fumes from the motor burn off and it is located in the exhaust tube/s under and around the center console area under the car. After the cat. in the piping is a resonator/silencer to help get rid of that honda sound. Then after the small resonator tube is the big "muffler" this will change the entire sound of the exhaust to what ever kind that you want...almost. It looks from the pics like you have no resonator and a glasspack style muffler...prolly really loud huh? Put a resonator tube back in...IMO. Oh and your Muffler is what we call a FART CAN!

Really loud without the silencer i have put on. Im not sure if the silencer is killing horses for me though. I hear it does and doesnt.

Kool, i got a "Cat-back" exhaust for like 50 bucks rather than paying 850 like some that ive seen. And as i hear a lot, neither exhausts dont give HP at all so no complains from me anyway.

Hugo, an exhaust makes a difference on FI due to the amount of gases you're dealing with. With our cars in NA form, the exhaust flows enough for the amount of exhaust gases produced by combustion. However, when you introduce FI, the amount of air and fuel going to the engine increases. Therefore, the amount of exhaust gases also increases. As such, a better-flowing exhaust will show more gains on a car with more exhausts gases vs. a car with less. Make sense?

So you think the "catback" i have now will do good enough?

You don't have a cat-back exhaust. You have what the Honda guys call an Axle-Back exhaust. You can see the problem in this picture, look at the right side, the pipe is collapsed to like 1" thin to fit under the suspension.




For reference, this is what a cat-back looks like:

eeehh, oh well. Im leaving it as is. Ive been spending a lot of freaking money right now. Im still debeting whether to get that check valve or not. I still have to buy oil, oil filter, possibly spark plugs (depends what my dad thinks). After that, i want to dyno my car. Im gonna be spending more money on gas since i will be running premium. Im not complaining, but i know in the end ill be happy.

Dusten beat me to it. You just have a stock exhaust with a new pipe and muffler welded on from the axle back, not a full cat-back; the only thing you're getting from it is sound. And actually, there's a chance that you might actually be losing a bit of power, as the exhaust gases slow down and lose energy when they reach the new, larger tube and expand.

Heres what a cat back should be with a silencer. Since you will not ever really gain power from this mod I would start thnking about nice sound! The reason cars sound throaty and not "poppy" is usually due to a silencer...

^^^^^^^^^^Nice graphic!^^^^^^^^^^^^^

The silencer (or resonator) doesn't need to be pink though....

Is that your real name or nick name? Dusten I never heard anyone called dusten besides that pongo pygmaeus that comes out in Dusten Checks In.

Put it this way,my friends gt has no cats he removed them and put in a X pipe and a year before that he put in magnaflow magnapacks in. When his car is idling it sets of car alarms,yet it is a v8 and is louder than a 4banger without cats.
