I have a stock S2000 and want to put in the test pipe. Just wondering how much louder does it get. I also want to put in the AEM v2 later on.

 

yes it will get louder and deeper .... if you have an aftermarket exhasut, it reduces the drone on certain exhaust systems..

 

Thanks - do you know of any HP gains?

 

so you want to put a test pipe on your stock car? why?
sounds to me like youv got a stock header and a stock exhaust, why whould you put a test pipe on your stock system, thats not going to do anything, your stock exaust isnt goin to get any louder, im mean it might be a tad different sounding but it will just sound stupid and you will gain no power at all, i whouldt be surprised if you lost power the way these cars are

 

I would like to free up the exhaust a little and put in the AEM v2 intake.

 

a test pipe with the stock header and stock exhaust is not going to free up any power, its going to be a waste of money and time

 

Put your AEM V2 on first, enjoy it. Put the test pipe on when you get header and exhaust.

barely. your exhaust only flows as well as the most restrictive part. with a stock exhaust setup, that will be your cat or muffler. You may gain a fraction of an HP with a test pipe on stock exhaust, but you won't see much of a gain unless you replace the header and catback too. Also, this is true for any car, I don't see why you have to own an s2000 to understand this.

 

the muffler"S" are not restrictive.

anyway this is not about power, but sound.

with the test pipe the car will be louder as well as raspier...like a raspy 350z/g35. you could acheive the loudness without the raspiness by simply removing the resonator.

 

or you could not be a cheap loser and just buy a freakin aftermarket exhaust and header to go along with the test pipe you want

No matter how you put it, two twin-loop mufflers aren't going to flow as well as a single straight through. Switching from a dual to a single doesn't necesarily increase any power, it just shifts the torque band a bit. With my exhaust, I notice a bit of sluggishness under 2500 rpm, but response and torque at 4000-6000 is a bit better according to the butt-dyno. I'm guessing somewhere around 3-4 lb/ft of midrange. Top end flow is a bit harder to gauge with VTEC, intake, exhaust all screaming at the same time, but I bet its 1-2 hp there too.

And then there's the whole weight savings thing...

thats where you're wrong... ... it's amazing to me when people that don't even own an s2k think they know all about it....

we all know the s2k's i/h/e setup from the factory is very efficient..... getting aftermarket i/h/e doesn't really give you much hp.. you'll be lucky to get 15hp out of those three components without tuning...... however there are some slight exceptions.. (j's header + j's 70mm header back being the best of the group) and we all know single exhausts give more power then duals......

but when you think of biggest bang for the buck.. a test pipe is better then all three.. and it's been proven..... $100 bucks for a test pipe.. matched up with a stock header and exhaust will give you around 3-5rwhp.. (there are dyno sheets on s2ki).... and there's dynos of a test pipe adding up to 10rwhp or so on a car with an aftermarket header and exhaust.....

i was going to say the same thing...i will add this. the t1r dyno that was around a year ago showed that the test pipe alone made most of the power...i just can't justify making the people that drive behind me suffer...i hate being behind old cars that spew smoke and unbreathable air. maybe i'm just getting old

 

Will you get the check engine light to come by putting on the test pipe?

 

yeah the s2k's i/h/e set up is far from your reg. B series set up...the exhaust and header is already well made from the factory so please stop spreading false information or information you have no idea about...

and yes, the test pipe WILL cause a cell unless you get the plug fouler or get this from s2ki...i think the GB is over, but its about 125 shipped from what he told me...

ill add this, i wouldnt knock the guy for putting a test pipe on his stock car. a stock with a test pipe Should gain power,especially with a v2 on the other end. Also i dont understand all of you guys saying the stock manifold NEEDS to be replaced to benefit from a test pipe, thats absoloute BS. There are maybe 2-3 header i would conisder better then stock, therest are all dogsh*t. i would recdomend header in this order 1. J's racing, because bigger is better on this car i dont care what the hell you half to tell me about back pressure, its all bs i have done like 30+ dyno runs to know. 2.toda,well shaped nice size, all around good but for the minimal price diff. between the two i would by J's all day. 3 mugen to high price,all for the name but does gain. As a stockcar site the absolute most restrictive thing in the exhaust system is the cat, thus putting a test pipe in should make a nice difference. I would recomend installing a V2 at the same time, all of that should be like 300.- and i would expect a 10hp gain, if car (motor) in tip top shape.

 

The berktech test pipe is still going for 100 bucks shipped, I just got one. Hoping I wont shoot flames

he extended it to the end of this week i believe

 

my local shop made me one for 120 install ... made of stainless steel pipe and bolts ... now my J's 60 rs sounds a lot deeper and im loving it ... but the secondary o2 sersor isnt too happy lol

 

Did you use the spark plug fouler trick? I know using 2 makes ur car runs a bit rich, 1 leans it out a bit but still keeps the CEL away.

 

nah i didnt bother ... the car is going for storage this winter and next year time AEM EMS and wide band and some other new stuff ... stay tuned

 

Stay tuned? I will BE tuned. =D

EMS is the expensive and right way to solve your problems. The spark plug trick has been tried with success (AP1 in sig), so I was just recommending it.
