I was just curious to know if anyone can tell me the approximate HP gain I would get in my '03 Civic SI if I added these parts:

Injen Cold Air Intake
Greddy EVO2 catback Exhaust
DC Polished Headers

any helpful info would help thanks!

 

what kinda header? shorty/longy/racey?

 

it's the 4-1 One peice....so it's a shorty

 

well with those mods id say 15-25 hp window... just a guess. Id go with a race header if I were you tho, if u dont mind finding a way around smog tests... I have had a shorty then got tired of it and got a race and wow... BIG difference.

 

Who makes the race header? Does DC make one? Which one did you get?

 

yea dc makes one, I got the dc brushed race header... only prob is that it replaces the cat... so yea... u wont pass smog

 

So I won't be able to use it with my Greddy EVO2?

 

is this the one you have?:

oh **** i forgot u had an ep3 lol. um they might made a longer header for your car that bolts to the cat, im not sure on race headers for the ep3... what I did, I have a base rsx, I got the race header and built my exhaust with a universal muffler. So yea shortys dont have great gains

 

sorry to jack, but 3vil, did you get a race header for the type s or do they have a seperate base application. also did you get a sim card?

i got a race header for the s, they dont make one for the base then while I didnt have my exhaust I just had stoney at velocity cut my b pipe and make it work (since I have a base), then got my exhuast built when I got my JIC in... I didn't get the sim, I'm just gonna get kpro anyway so. I hardly ever throw a code anyways its weird.

Why dont you add the parts, dyno it, and you tell us? These kinds of posts are useles and pointless. how can anyone speculate anything without a dyno session to back up the claim?

This is NOT whp. you can't add up what each part individually gains and say that what youd get. What are you basing this guess on anyway?

Sorry again, I go by WHP oh well... and my guess is just a guess but is kinda compared to my car with exhuast, race header, and intake... and i dynoed mine.

You shouldnt contribute to such a pointless thread
