seriously i love altezzas

okay i aknowledge that people send a lot of money of the altezza style tailights but its has gotten to the point where they are just played out and a great percentage of the alltezza companys customers are the people who just buy them to be cool, you know that guy with the f&f decals on the sideand the 5" exhaust tip. so all in all i think i have been a little hard on the people who acually spent money on the product to inhance or modify there vehical.

p.s. i dont care what anyone says, "dual exhuasts civic" its like a paradox.

The S2000 has dual exhaust cause it's making 240hp. If your Civic is making that much power than I can see having a dual exhaust.

But hey it's your car - you do what floats your boat. I'm just trying to show you the performance side of dual exhausts. I'm not going to tell you what to do and what not to do.

Have fun!

As I understand it from the FAQ and some other articles and books, back pressure is the low pressure zone behind an exhaust pulse that creates a type of vaccum and pulls the next pulse along with it. It would then seem to me that dual exhaust, if done right, wouldn't hurt. I would do a dual with smaller pipes though so that your exhaust pulses dont get the opportunity to turn around or clog up on you - more room to flow can also mean more room to build up.

I think that a dual exhaust really is all about looks when you think about it. For our cars (civics) you don't need that much flow, you just don't. You can do dual with smaller pipes (stock size) or you can do a single with a wider pipe (2-2 1/2") and get the same high flow.

So yeah, I think my opinion here is a combination of everyone - do it if you like, it'll certainly stand out which is what you said you wanted, but as far as performance goes, depending on how you do things, it wont really matter dual or free flow single.

just my $.02

ps: yeah Altezzas are poopy, they're like a$$holes - everyone's got one, make your own it's fun!

or u could just not have them at all
what about the exhaust where it comes out infront of your rear tire like on the side of your car, is that hard cause i like that

The S2000 has dual exhausts because who ever styled the back end of the car thought they would look cool.
You could put 6 tips at the back, or just one and if done correctly it would still make 240hp.

Now this is finnaly some orginal thinking.
I believe exhausts are like arseholes, and should be kept hidden from public view.
Look at all the new European cars, they all hide the exhaust behind and under the rear bumber, the result is a very clean and smooth look to the back of the car.

If you really want to design an orginal and IMO attractive show car then try hiding the exhaust, and keep the back of the car clean and symetrical.

thats a good idea
i think im going to have to try that one and u wouldnt have to spend money on a tip cause who cares what it looks like cause no one can c it

What kind of thinking do you have? A higher hp engine needs more flow, duh. Anyway this is pretty much mute. I'm done with this subject. He can do whatever he wants.

No if you put 6 tips at the rear you would prolly have less one sluggish car. Believe me when I say the reason the S2000 has dual exhausts is because with 240hp you need a higher flowing exhaust system. And there is a reason a Civic has a single exhaust.

but this has been overkilled. He can do this mod or not I could careless. I'm trying to point out the benefits and non-benefits of a dual exhaust on a low hp car.

Stop and think about that for a second.

Think about all the cars with more than 240hp that dont have a dual exhaust? are you telling me they are breaking the laws of physics?

Or what about the fact that most of the aftermarket exhausts for the S2000 are a single system, do they reduce the cars hp?

Or the simple fact that for about half its length the S2000 exhaust is a single pipe, its only split at the back for style.


Single or dual, if designed right both are capable of the same flow rates.

You are right but think of all the cars over 240 that DO have dual. More than not huh. Maybe those engineers that get paid thousands and spend years designing cars know what they are talking about.

You can make a dual exhaust that flows just as well as a single exhaust - don't get me wrong. I also forgot to mention the reason for the longitudinal placement of the engine, and the dual exhaust (and of course other factors) is also for weight distribution.

Having dual exhausts will balance out the weight of the car just like putting an engine in longitudinal.

But yes you could have the same flow rate of an exhaust dual or single. I would believe the dual exhausts makes the car better balanced. Ever get a Civic corner weighted? It's not pretty. The S2000 is one of the less expensive BEST balanced car for under $34,000.

I have recived many insightful comments and suggestions from many of you and am appreciative. I was wondering though, would I necessarily need a whole new bumper to accomodate two exaust pipes? I have looked into the whole process and one shop wanted to charge me $250 for a new Black Widow bumper and an additional $250 to paint it. Is there any way around this?

[Jetts]

get a saw and cut out a space identical to the one on the other side or close to close to it

I think Dual Exhausts done right look good, here is a pic of my friends Dual Exhaust Setup....
