i never really noticed anything since i have it off time to time..but wat gains are there...just unbolted from the back...is having a exhaust more power...cause i think unbolted gives out more power...can someone describe.

 

I don't know **** about Preludes, but what I can tell you is unbolting your exhaust is ghetto and rice all at the same time. You won't gain ****, so don't do it.

You're wrong.

yes unbolting your exhaust sounds like ****

but if done with a good header, you pick up a good bit of power, why do you think drag cars run open header?

Think before posting

 

You would loose torque but gain top end correct ??? because of the loss in backpressure ?

 

ugh

I thought the backpressure myth had finally disappeared....you make more power over the whole powerband open header

2point6 has some good dynos that could show that....

 

i have run open header and it felt as though i had lost down low (butt dyno)....... maybe we should clarify that statement though more power "tuned" ....is that correct ? or were those sheets with stock maps/untuned

 

of course you would want to tune it to make the best power

 

but will it make more power over the whole band untuned ?..obviously tuned would be better and make more power

 

nobody can say whether it will or wont untuned....there are too many variables

you can't make assumptions based on your feelings. only sure way of knowing whether it does or not is to dyno it. tuned of course. untuned would just be pointless.

 

thats why i wrote butt dyno in there because its a feeling.... and as we all know a the butt dyno isnt always accurate. I thought everyone would know wut i meant when i put (butt dyno) &lt; like that

 

okay...so do i lose power???cause it seems like i make more power through high RPM's and when shifting into the Vtec area..

 

How much "power" are we talking about here again? To me 3-5whp (if that) at the top end of the RPM range at the cost of annoying droning and an absolutely ghetto sounding exhaust isn't worth it, especially if it's your daily driven car.

On a race car, it's a different story but I'm sick of seeing ricers in Civics running around with an unbolted exhaust.

 

cutout ftw

 

:raises hand:

i havent been running the axle back to my N1 for like 3 months now

NO hell no you will gain power untuned

BUT gain far far more tuned and you would have to be stupid to run anything untuned!

lol

sounds like a bureaucrats answer!

look who cares how it sounds as long as it is making power and i will go on record saying that i love the sound of open header every time i hear it

it is people like you sir! who stop people like me from been able to have fun damn bureaucrats and there obsession with sound!

if you do not like it wear a set of ear muffs LOL

DONT EVER SAY THAT AGAIN LOL backpressure is a damn myth

 

I ran my parts Civic open header. It became the world's slowest dragster

LOL. Maybe it's because I'm a turbo snob. I don't need to unbolt my exhaust to gain 3-5whp. My car can gain anywhere from 10-15whp just from the sun setting and a nice chilly breeze.

Yess we all know now that tuned you will gain power. But that wasnt the question.... does anyone have any dyno sheets or other proof that untuned you will or will not gain power ? If so where in the powerband and is the low end torque lost ?

 

okay so I do gain nothing then from doing it...as i have experienced it seems to give more power then having an exhaust..although it does seem like the exhaust gives more of an high end....I dont know how this thread got to open headers...but I thought you lose a lot of power doing this unless your running a turbo setup which would be perfect for it..

 

I am one of the few people I know that has a gutted interior for a daily driver and loves the way the car sounds ALL the time. I bought a header and couldn't get my catback hooked up about 3 months ago. The car was absolutely deafening. Granted, I did LOVE running all the way through the revs, but all it would take is a week or so before you had noticeable hearing loss.

and butt dyno said yes, it's quicker.

I bet you wouldnt see the power loss on a hot day if you plumbed in a 5 foot wide by 4 foot tall roof mounted intercooler with about 24,000in^2 of cooling fin surface!

Even with that, you would be killing anyone else that is within 50 feet of you. If you go full throttle past someone with their window down, you're going to **** them off. If you go run on a track, by all means, do it. It seriously isn't for the streets.
