proven fact is that the ka likes forced induction.
nitrous or boost or go home.
its plain and simple.
the only people making power with a ka are stuffing it full of something other than plain ole fuel.

^youre right on the velocity being important. however, it has been proven multiple times that the bigger the exhaust you throw on the more power you will make. 3" is the best. you may lose some part throttle response, but you will gain power throughout the powerband
I think the point he was tryin to make is that a 2.5" catback will gain "better" overall power compared to a 3". "Better" being most people's opinion that having low-mid power is a lot more fun that high hp. Unless you like goin 100 and +

And he was wrong.

lol what is up with the graph? If you look at the plot lines on the graph, the torque curve of the 3" is definitely lower than the other exhaust, but the numbers below list the 3" as higher torque than the other. I call shenanigans!
FYI, those dyno's are not on the same scale, so it is a tad difficult ot compare, but you can see the 3 makes, and Holds more power from middle to end. Only in one small spot does the 2.5" make more power.

Lets all put stock civic exhaust on and call it a day. Thats a whole lot of back pressure coming out that one inch pipe. Truth me told my Girls civic hatch with a fully built integra gsr motor in it had a 3 inch exhaust on it till she got pulled over for the bees in the exhaust and we then put a stock muffler on the vehicle (one inch outlet) The gain from this on street was insane. It was a night and day diff. The car did suck on highway after that. We have since put a higher flowing type r muffler on the car and gained the best of street and highway. I know its a honda and I have read countless threads about how the ka loves the big exhaust. I am a believer that ever motor is diff and wants diff things. Can we all get along?

^eh backpressure is NEVER a good thing for an engine. a little restriction just helps with throttle response.
personally and what I believe to be the best type of exhaust for anyone with an altima would be 2.5" piping from the header to the cat, and 3" piping from the cat to the muffler. then just make sure that the muffler is of good choice (not a straight through design).
to anyone who disagrees with me, screw you. look at the graphs iceman posted... lol

I want to use flexable dryer venting as my exhaust. HAHAHa

You mean the one with the inconsistent torque numbers?
Hey, why bother with a 3" at all? Obviously if a 3" makes so much more power than 2.5", why not go with a 3.5"? Or a 4"?
at 4" youre probably going to have clearance issues, not sure but probably. and dont you think thats majorly excessive?
and i wasnt talking about the one with inconsistent tq numbers, the other one smart ass that graph is obviously off tq and hp dont meet up at the right spot or so it seems... the other one is undeniable though

Of course I think it's majorly excessive, but I'm an ass and I'm using an over-exaggeration to prove a point. Sure, you will get more horsepower with a 3" over a 2.5", no one can disprove that as Ice has already shown plenty of consistent dynos to prove it. But you do lose things in other areas, such as throttle response, noise, and even a broader powerband in some cases (you narrow your powerband, making the horsepower peaky).
My point is just because you make more power doesn't always mean it's the right thing to do for your car, but I guess it depends on what you're running and what you're using it for.
And to anyone mistaking back-pressure with flow, they aren't the same thing. Smaller exhausts have better air velocity, or in simpler terms, the air exits the exhaust at a higher rate of speed. This is because of the pressure difference between a smaller and larger exhaust and why smaller exhausts have better throttle response and better feel for torque at lower RPM's. H
However, larger exhausts flow more air (I wouldn't say they flow better, just more), but the air doesn't come out as quickly or speed up as quickly, which correlates to the decrease in throttle response and sometimes a lack of bottom end horsepower or torque. It's the same thing as the garden hose effect of putting your thumb on the end of a running garden hose; the pressure change makes the water come out harder/quicker, but not necessarily flowing MORE.
If I were to pick a perfect exhaust, it would have to be made with a flow bench to ensure it not only flowed more air but did so at an equal or better rate of speed, which I'm sure most cheap exhaust makers don't do.
