^well unless you go turbo then its an easy game, but hes right midrange is extremely important in s's, and with those you should def feel the difference in performance driving around

 

You could see more gains with a test pipe and a nice 70mm exhaust.

 

test pipe = most gains per $$ ~8hp??
intake = easy gains in all the right places ~ up to 8hp with the right one
exhaust = limited gains, opportunity to save weight, chance to make car sound a little better ~ 0-4hp gain depending on system

 

the test pipe is the most "bang for the buck", but 8hp? I'm pretty sure you won't get that much out of it. But for $100 or less, you definitely can't beat it.

I used to have a Chrysler Crossfire, and I know a lot of guys who bought the Borla exhaust for that car, then welded the stock tips back on. It looked completely OEM, but the sound was unreal. I haven't heard the Borla system on an S2000, but I'm pretty sure with the right tools, you can get your stock tips on anything!

 

test pipe = 6-8hp.

 

An intake wont get you more than 4whp. You can achieve that much from just switching to a K&N filter on a stock box.

And a good 70mm single exhaust can get up to 12whp.

Although your right about the test pipe. Most hp per $. 7whp gain right here.

 

I have to disagree. Invidia v3 dual loses power over stock. I dyno'd 196 in my 00 stock, 194 with the invidia

 

I'm pretty sure that Borla exhaust isn't gonna get you any more power, either. It's a 60mm dual, so it might shed some weight (being fully stainless) and will sound nice, but that's it.

 

Thanks for all the responses. I think I will stick with the K & N FPIK and High flow cat. I dont want CEL issue or a smelly car otherwise I would get a test pipe.

I will wait on the borla until I see proof it doesn't cause a loss in power.

These two relatively inexpensive mods should make the car breathe a little easier.

I was also planning on using eibach pro-kit springs simply for a better look. Anyone have reviews on these springs?

 

definitely K&N FPIK ftw. also a high flow cat will free up a few ponies.

There arent really too many dual exhausts out that make any noticable gains. One i know of that makes gains is the T1R Sparrow. They have a new version coming out that has the "dolphin" blue style tips and is designed to be quiet.
