My gsr during vtec feels a bit..restrained, like it wants to breath. I think a test pipe would really help it flow. Oh btw here's a link to my GSR during vtec.

I plan to put one on my car in the near future.

to living somewhere that does not have emissions. woo hoo

 

I driven a few cars with test pipes. IMO I kind of think that OMNI power test pipes are fairly decent for the money you pay...but that's just me..

 

Just a test pipe will not help much at all. The diffrence between a test pipe and a aftermarket cat is at the most 1hp if that. I have seen alot of posts and dynos to back this up but dont feel like looking. My suggestion to you is to not think about buying parts here and there, but to buy parts that work together thus giving you best results. You dont need to be buying just a cat or just an intake for example. It takes many parts working together to get results you are looking for. Do some searious reading and research before you buy anything. Go to http://www.team-integra.net they have some awsome reading.

 

I run with a test pipe and it did help out a bit. Plus i was using an old clogged up cat so the test pipe helped it breath a bit more.

 

Why is it every other knuckle-head thinks a test-pipe is the answer to everything. Oh and BTW, it doesn't matter if you don't have STATE emissions testing in your area, IT IS STILL ILLEGAL!

Glad to see there are so many willing to keep that "ricer sound" alive.

You are not gaining anything by running a test pipe, more likely you will be loosing some in the low - mid range for "maybe" 2hp on the upper RPM (if any at all). It is money well spent for you to get a quality high-flow converter instead. Keep in mind, Federal law requires the use of one in ALL 50 states.

These guys I quoted are the only one's making any sense in this thread. A test pipe is a waste of a money, you are much much better off going with a high flow cat.

To everyone who said how their straight pipe made a difference, notice how they said "it felt like it made a difference". None of them would bother with real numbers or testing...

Do your research before coming to the conclusion that a straight pipe will "help your vtec breathe".

And yes....read the articles on team-integra.net.

 

t-i.net ownz all.
omni test pipes work fine my friend had one on his ls.

but like stated before if you just buy a hi flow cat or a straight pipe it wouldnt do much without a bigger b pipe and a header. thus

also like the other guy said it is illegal. you have to have a c.c. on your exhaust or your car will probably be impounded. atleast maybe here in cali?

The law also requires that you don't speed. I'm not saying he should use it, but let's be serious. Not everyone here is all that worried about breaking a law or two.

In any case I guess it's best to at least mention it. It's the thought that counts, right?

 

get a header and test pipe. youll be veryyyy verrrrrrry happy frees up alot of top end!

Just get a high flow cat....same power, better for the planet.

how do the costs of a test pipe and high flow cat compare?

and how come some people are saying that the test pipe doesnt help performance and that a high flow cat will do much better? cause they are deflinitly about the same.

and either one of them will make more than a 1hp difference if you already have intake header and catback. if thats all you need to complete those bolt ons that i would recomend getting one of them, probaly the high flow cat, for legal reasons and inspection, if you have it

Aggreed. I have an OBDII car with an OBDI jumper and ECU, the jumper says "for offroad use only" does this mean I am a bad person? Some things are not that big of a deal, at least in my eyes.


And that dyno graph would be great if I could read it.

 

Get the test pipe if you feel like it, but just think about it would you want to crawl under your car every year to unbolt it for emission and then jack your car back up and bolt it back on after emission and remember that bolts does tend to get dirt, jam/cross tread and rusty, if you like to do it then go for it I personally believe that its a hassel, I have a Magnaflow high flow cat and it was the bestest money well spent, I would never put a test pipe. and like all those other guys said you'll need other component to make everything works and produce good power, just buying a test pipe isnt going to do much.

 

I know alot of people have to go through that ^^^ and that is their decision. But not everyone. No emmissions testing here at least. I will probably end up getting one, and for the record I currently have a DC header (swapping out with a Toda soon) 2.5 header back to a twin loop.

You cant see how the two curves are nearly identical? You dont need to read the numbers, that's irrelevant.

 

Well if I am looking at a dyno graph I would like to be able to read it. But maybe that is just me.

 

....it's just you.

 

2hp difference.

ah, noted for future reference that I no longer need to read dyno graphs. Thanks man, all this time I was under the impression of the wrong thing

 

i rather go high-flo cat. i think test pipe is just more noisey. lol

 

That is the slowest GSR i've ever seen. I know its an automatic, but it looks more like my old LS

 

In response to your title... No. Buy a nice header (i.e. Toda, Hytech, SMSP, RMF, DTR-SSR) instead! Then you will really feel some gains.
