Poll - Dual Exhaust - Civic?

Too much drop in backpressure results in a loss of lower end torque and sometimes, an unstable idle. The best dual exhaust would be from the cat to a muffler, to a y-pipe, and then to the exits. This way you'll get the look without too much drop in backpressure. It'll save you money too.

What about weight gains?

Then again depends on how much go you really are.

Thanks for the help guys!

Yeah, weight gains too... but I was just sticking to the backpresssure issue.

backpressure is defined as resistance to flow, which is not good....the reason there is a drop in torque is not because of backpressure it's because of the pressure change from the cylinder to the exhaust system...when you increase the piping size (actually it's the area, but we'll just put it in simple terms) the air velocity slows (not because of backpressure)...when a fluid, like gas slows down, the pressure gets higher and then the pressure drop from the cylinder to the exhaust passage is less and that robs the torque. Backpressure will just slow down the fluid flow even more creating even less of a pressure drop and then you loose more power. You've been learned my friends

So basically you've added your own definition to backpressure and said what's already been said.

backpressure doesn't = cylinder pressure-exhaust pressure

backpressure=resistance to flow

if you don't believe me, I'll just shut up and let you think the wrong thing...if you do believe me, then you can learn something new...choice is yours

Egad, my ego is in shambles. I don't really care.

Ah let's not worry about it fellaz.. the poll was just for how it would look anywhoo

Thanks for everyone's help though!

Hehe...you posted the "Mortal Kombat" car. I love that kit. I like his grill a lot too. Did you get my last email?

Hey Mike - this one? "The panels and dash were redone with vinyl. I'm not sure the specific color, but the body color....." I got that one and replied to it and the one that said "Did you get my last email"

Are you talking about the lower grilling? Is that just some inserts for show or is that a type of grilling? I liked it too but it looked like just for show

Err.. dual exhaust on a 4-cylinder engine? That's stupid. Supras push 800-900RWHP with single exhaust pipes all the time.. why should you need dual?

And the pictures of that kit you posted, haha, what's the point of having a huge opening in your front fascia if you're going to put a plate behind it? If your car isn't turboed with an intercooler what's the point?!

There's always one

LOL Yep, there's always one. WTF was he talking about anyway? But yeah, I asked that guy where he got it, and I think he said he found it in his dad's garage or something. LOL...I just think it looks cool because it's solid looking.

LOL Shweet - hey have i asked you this yet? But do you know if your side skirts toward the front are actually flush up and down like the stock side skirts (this shape |_ ) or do they flare out like this kind of shape /_ I can't tell!! People are telling me that it is different angles that makes it look that way.. but i just dunno!

Never really noticed, but I'll try to send you some new pics pretty soon.

With the right kit (like in the pic) I think it looks tyte!!

exactly, but it's all for show, it wont really help performance

Nope, keep it one exhaust, dual tips are ok sometimes, but keep it on the right side, thats what i think.

the duals on the civic looks pretty good

As stated in the first post

I know there wouldn't be any performance gain - more or less just weight gain. However, for look purposes, what you think?

Key words: know & look purposes
