Re: greddy evo 2 question

straight pipe is what i have right now: no cat, resonator, or muffler.
your aftermarket system has all of them.

Re: greddy evo 2 question

you can do a test pipe and have no cat but a still have a resonator and muffler to keep the sound level down.

Re: greddy evo 2 question

Yeah it's called a test pipe, a straight pipe is what Nick just described. And yes you can put it on your exhaust, they're pretty universal. They're also illegal in most states, you won't pass emissions.

Re: greddy evo 2 question

A straight pipe is not a part, it is just a description (no cat, no resonator). But to answer your question, your only option is by removing the resonator (since it after the cat). But it would not be considered as a "straight pipe". Also there are 2 option's if you really want a straight pipe.

1. Get a test pipe, which is completely irreversible, so when it comes time for a inspection, unbolt the test pipe and switch back to your car and reset the ECU and you will pass. FYI test pipes are fairly cheap, but your check engine light will be on, so don't be surprised. And if you get busted by five o because of it, just say that you had cat removed after you got your inspection.

2. If you know somebody in the inspect bizz that can pass you (cough), then you are home free but you are paying extra because there a** is on the line because of it. FYI if you don't know someone or you don't know somebody that knows somebody etc... Then it will be tough to find one, the fuzz have been crackin down hard and most inspection station's just don't want to take the chance anymore.

Re: greddy evo 2 question

Im sorry, I am having trouble understanding.

Can I put a strait pipe on with the Greddy?
If I put it on, is it easy to switch out?
Or is the test pipe a bolt on, and a strait pipe a weld on?
Does the test pipe give the same sound as the strait pipe?
For the check engine light, cant i run a code on a code reader and hit "Clear code" for it to go away?

Re: greddy evo 2 question

a straight pipe is just a "term", there are not products called straight pipes that you can buy for your car. A straight means you exhaust system does not a cat, resonator, and muffler, which means there are no restrictions after the headers.

here is an example pic of what I am talking about http://www.quickhonda.net/images/exhaustpics/Image3.gif, now imagine this except everything is cut off after the headers and is replaced with pipes welded in, giving it a straight through design aka straight pipe.

here is an example of a test pipe http://www.omnipowerusa.com/Images/P...Pipe_Large.jpg
looking back at the diagram, this pipe would replace the cat, but without have any welding needed. You see those holes on the test pipe? those match and bolt right up to, if you are going to replace the cat with it. Making it a lot easier when it comes time for an inspection, instead of having a pipe welded on there.

yes it will give the same sound, i would suggest you keep your resonator on though, by removing it is pointless, you will no get any gains from it, its all show and no go, unless you just want to have your exhaust a little louder.

Clearing the Code will make it go away, but not forever. It will come back on. Why? because the O2 sensor will know that the cat is not there. http://auto.howstuffworks.com/question257.htm

Re: greddy evo 2 question

so a test pipe is the easiest way to go....but doesnt the engine need back pressure?

if you remove the cat, and resonater, it has no back pressure, correct?

Re: greddy evo 2 question

no the engine does not need backpressure.

The engine has to work harder if there is more backpressure
backpressure = less power

Imagine yourself trying to push a car and the goal was to make it go as fast as possibly. You would have to remove a lot of weight, so that there will be less friction (pressure) being applied to the ground, making you work a lot less harder and making the car go a lot faster while you push.

yes back pressure equals less power but too big of an exhaust equals to robbing power..

ever wonder why aftermarket exhaust companies make 2 1/3-3 inch pipes for the prelude and not 4inch or more?

youll lose power on a stock/lighty motified motor with such a big exhaust..
