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! __________________ SPEED IS NOT AN EQUATION CONSISTING OF DISTANCE DIVIDED BY TIME.

I hear it does and doesnt. | | | 09-27-2006, 01:33 AM | #4 | Senior Member Join Date: Nov 2005 Location: çî†ÿ øf åNgëL§, CA Posts: 5,314 | 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. | | | 09-27-2006, 01:34 AM | #5 | Senior Member Join Date: Aug 2005 Location: Melbourne, Fl/Athens, AL Posts: 393 | 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? __________________ -Kenny | | | 09-27-2006, 01:37 AM | #6 | Senior Member Join Date: Nov 2005 Location: çî†ÿ øf åNgëL§, CA Posts: 5,314 | Quote: Originally Posted by Variance Hugo, an exhaust makes a difference on FI due to the amount of gases you're dealing with.

Make sense? | So you think the "catback" i have now will do good enough? | | | 09-27-2006, 01:46 AM | #7 | doesn't care about you. Join Date: Aug 2004 Location: Denver, CO Posts: 3,925 | 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: __________________ '99 Dinan M3 | | | 09-27-2006, 01:50 AM | #8 | Senior Member Join Date: Nov 2005 Location: çî†ÿ øf åNgëL§, CA Posts: 5,314 | 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. | | | 09-27-2006, 01:51 AM | #9 | Senior Member Join Date: Aug 2005 Location: Melbourne, Fl/Athens, AL Posts: 393 | 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. __________________ -Kenny | | | 09-27-2006, 01:57 AM | #10 | Senior Member Join Date: Apr 2006 Location: Southern California Posts: 456 | 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... __________________ SPEED IS NOT AN EQUATION CONSISTING OF DISTANCE DIVIDED BY TIME.
