Hey, any one know what the best exhuast is out there for a 2004 Civic EX Coupe. For the exhaust, is there any exhaust that does nto sound loud, instead it makes a sporty sound look in the mid-range instead of this DEEP sound, kinda like the one from Tokyo Drift?

well that noise can sometimes be helped by your intake, and if you're gonna get intake i suggest u use AEM V2 Cold Air Intake. And then maybe combine with GReddy exhaust. Depends how much you're willing to spend on your car.

Well, I already have a Aem V2 intake. So suggestion will be a Greddy Exhaust huh. Skunk2 will work?
I actually jsut bought a V2 intake, will put it on as soon as it ships in. Is it any good? Hey, thank you for your opinion, if you got any more, do let me know. Thanks yo.

by the way, V2 intakes are pretty much short ram, right?

Hey, the AEM V2 intake is really a short ram right?

 
Rep Power: 229

haha not quite .. you can make it as long as u'd like. it can LOOK like a full ram air but its still not the real thing. What i have is AEM V2 intake, A'Pexi Exhaust, megan racing header, msd blaster coil. Thats all my modifications and i've increased my civic from .. 100? to 160? hp.

Not another one of these posts.... ok... here we go... THE V2 is technically a short ram cause its filter still sits in the engine bay....

As for those mods bumping you up to 160hp... lies... lies... lies... unless u can back it up with some proof.

As for exhaust, just search! u will find countless threads. Most people will say Evo II, HKS Hi-Power, or a Magnaflow.... for a more mellow tone like a g35, 350z, i think the quietest exhaust on the market for our cars are the RS*R exhaust http://truehonda.com/inventory.php?a...ctdetail&id=27

thats all the help i can give you, im trying my hardest not to flame, like i know so many others will

the only exhaust that will give you that sporty midrange sound is DC sports TCS but good luck finding one i dont think its made anymore.

why do u say im lying? lol. and i seriously am pumping anywhere from 150-160 hp. how do u want me to back it up?

 
Rep Power: 512

dude.. you're MAYBE running 115 at the wheels.. go get it dyno'd to tell you the truth.. bolt ons really don't do much at all except give you a different sound and shift your power band around a bit.. I'm boosting at 2.5 psi and making 143.7 at the wheels..

and the V2 sits in the engine bay, so it's still a short ram.. It's not an adjustable length intake..

what kind of engine do u got in ur civic?

D17a2

 
Rep Power: 229

ok thats really weird ..? lol i run a d16y8 stock engine i guess but .. mines bhp i guess i wasnt thinkin about it .. who knows about whp.

 
Rep Power: 812

well whp is what counts, thats what moves the car

 
Rep Power: 229

true. i have no idea how much whp i have i havent ever dyno'd my car but the avg hp gain said to be given for each mod adds my hp up to about 140-160 (min/max)

 
Rep Power: 242

well for our d17s bolt ons don't do much. I noticed better acceleration from an upgraded suspension and almost no difference from my intake

60 horsepower increase from a header, intake, exhaust and ignition?

even from factory "claims" in horsepower increase you're looking at 30 horsepower.. that's assuming they "claim" a tad less than 10HP increase per item. Realistically speaking you're going to see 0-3 horsepower (if you're lucky)

Even in Import Tuner, they dyno bolt ons and see minimal results, sometimes negative gains (read: HP losses). There have been countless times where I read the Import Tuner power pages and see a "gain" of -XX HP or so by bolting on an intake or something..

And I'm spent..

this is a great thread..

so you have a d16..so u dont have a 7th gen.

yea u cant really go by what a website says when u buy theyre product. think about it. if you were trying to sell an exhaust system that you created with your own company..would u honestly advertise a 3 whp gain? of course not, thats stupid. so just exaggerate a bit... you cant just add numbers up u know?

get it tuned so then u can be very dissapointed..as most of us will. the only way to reach that 160 whp is boost..wether it be turbo or supercharger in ur case. or nitrous ...but that dont last 4 too long anyway so yea.

 
Rep Power: 812

ya i remember that. 2whp from dc sports exhaust and 3whp from intake with some torque loss.

Dang, it is sad that SO MANY get tangled into thinking they have gained so much. Guess they are getting the placebo effect. But indeed, sometimes you just want to "look" fast. Sometimes you just want results now. No matter what it is, bolts ons, kits, etc. Waiting while you get enough cash for a swap, turbo, etc... man, excruciating. Wow, 2whp from dc sports exhaust and 3whp from the intake, dang....

I think it should be mentioned that regardless of the vehicle or the engine, bolt on's like exhausts and intakes don't give you much power anyways. Opening up the breathing ability for a car allows it to gain more power when you change other things.

 
Rep Power: 229

like change what? im all ears.

 
Rep Power: 260

actually...thats pretty contrary. the majority..of cars that you add basic bolt ons too..do not respond as well as advertised and you're right they dont give you much power.. but..there are sometimes when basic bolt ons really free up a motor and give it a nice noticable gain that could have been made from the factory. Our d17 motors...well actually all of the d-series honda motors dont respond well at all to bolt ons..they actually dont like it very much at all. they were made perfect (in the eyes of honda and the ordinary consumer) from the factory. however.. when the first k-series motors were released, AEM was also one of the first to jump right on it and start looking for more power. The first cold air intake that was designed for the k-series motor put out a huge 12 whp and 6 wtq (of course it was at a higher rpm that u wouldnt usually be using in normal driving conditions) . regardless it was an amazing gain. when dc introduced its first production ready header for the rsx k-series, it lost 5 whp and 3 wtq. another example is the subaru sti. It also responded very well to aftermarket headers and intakes systems. a more popular example is the toyota supra.. ready to keep up with base porches at the track with a few minor bolt ons. Trucks and suv's are the same way.. you can always feel a noticable gain from slapping on a simple k&n intake system on a dodge ram or even smaller trucks. its just how some motors are made. not all of them are useless with bolt ons.. if they were, then soembody would catch on by now and these companys wouldnt still be in business. rememebr we really dont have THAT much support in the aftermarket field..aem makes intakes for almost every car application..so there must be some great benefit to some of these cars with some of these bolt ons..


but liek you said opening up the air-path does allow more gains with other performance parts.. itd be stupid to upgrade the valvetrain of a motor and still use the factory intake system. itd be useless to upgrade pistons and such without adding an aftermarket exhaust to free up the flow..so in that part ur totally correct. BUT...not all engines respond poorly to bolt ons.. THATS ALL im trying to say.. no harm here

 
Rep Power: 812

despite what people think, the motor was designed very well. head is free flowing, exhaust manifold is port matched to the head, IM is plastic to reduce heat soak, etc. alot of thought went into it. so when you slap on a header with huge pipes, obviously the air flow will slow down and youre gonna lose power down low. the more gains you get from mods, the more it means the engine wasnt designed well to begin with. one thing we have going for us is our engines run pig rich in stock form, so adding "air" mods will lean out the a/f mix. thats why tuning with boltons isnt really required. the ratio is already better than stock due to the added air.

exactly..are motors were created really almost perfect in hondas eyes and the everyday average joe driver.. our cars/motors were not designed with the performance enthusiast in mind.. thats why they released the ep3. we have a very good econo-box.
