i have a couple of questions you guys.


i have spoon single 60mm n1 exhaust on my s with test pipe and was thinking of adding headers.


but i was thinking today in the morning to buy the js racing single exhaust 60mm or 70mm.


now my question is how can i get the best powers gains?

will it be with the spoon single and just adding the headers? or


getting the js racing single exhaust 60 or 70?

and maybe later on adding headers to that system?

please help you guys
with the research

 

70 mm test pipe with 70 mm exhaust. Don't expect too much power, but u will get a little

 

even tho is a single??



before i had a invidia 70mm dual n1 with HFC
and now i am running spoon 60mm single with TESTPIPE


what if i add headers to the the spoon 60mm


wouldn't make much difference ?

 

Even with headers you will see very small gains.
If you want to make more power on a S2000 you pretty much have to go with ITBs or boost.

 

S2000's benefit from a test pipe only a little bit.

Installing a test pipe AND getting the car tuned by a competant tuner yeilds more gains than a test pipe alone.

As a general guideline, single exhausts are capable of more gains than duals (and weigh less).

What size is your test pipe? 60mm or 70mm?
It's best if it matches the exhaust diameter.

There are very few (maybe 2 or 3) headers that have been independently tested and PROVEN to make more power. The OEM header is very well designed from the factory. In my opinion, the $1200 it would take to buy a beneficial header could be spent elsewhere to make the car handle better, have more grip, educate the driver to be faster, etc, etc.

I agree with Danwolski, you either have to go ITB's (and bunch of other $$$$$ NA upgrades) or Forced induction to get big power gains from an F2xC motor.

There are 100's of threads on the forums asking your same exact question, in this case, "Search" is your friend.

 

yeah i get it i do search a sheet load but there is not much info in spoon exhuast idk why maybe not much people run this set up?
now i know for a fact i am not gonna get more than 50 hp or 40 or 30 or 20 or even 10 hp gain

i kno its hard to gain HP

i just want to kno what will give me better gain

the js racing 60 or 70mm singe exhuast

OR the spoon 60 single exhuast i have now

and my testpipe is 60 aswell

 

The Spoon probably yields minimal gains being that it's a 60mm. Same for the Js 60. The Js 70 should be the most although very marginal

 

If I do js racing 70 single with testpipe and header will it be mega loud

 

OK, thank you for clarifying.

The 70mm should yield more HP. The biggest thing I noticed going from stock to a 70mm testpipe and dual exhaust (untuned) was that it felt a little stronger on the top end via my butt dyno. Only with a tune was I able to achieve any real gains in the mid range.

I have never heard the J's 70mm single in person. You might search youtube to get and idea of what your car might sound like and how loud it may be. I would say it runs the risk of being loud.

I have the 70mm Greddy SE dual and it is plenty loud at WOT - and that's with 2 mufflers!!!! I would assume the single would be louder with one 1 muffler. As a comparison, I'm pretty sure the 3" Berk single is pretty loud - or so I've read here on the forum.

Good Luck with your decision!

 

I have the Berk 3 inch headerback and the invidia I had was way louder. Even with a cat.
