S2000 HKS Hi-Power

[Nickamsweet]

hey, just looking in to getting a HKS dual exhaust system and wandered how the sound changed over the age of the exhaust... I want something more aggressive deep rather than tinny/raspy and also something that is not too loud but louder than stock...

Cheers

Fuckin rev it man what was that like 2 thou?? If you did it for sound then let's hear it!

@Trooper45 @Trooper45 I'll make a new vid of it soon. It actually sounds different now that it's aged a bit. It might be a week or so though, I have no dash in the car currently. I'm doing a black to black/red interior swap.

I didn't put the exhaust on for power, did it for sound.

step hardly on the gas ,PUSSIES

Im running a spoon single on mine and i only got about 6 hp according to the dino(even with my oem hardtop its loud as hell over 6k. dingle is right ive seen dyno sheets from the fujitsubo(?) duel exhaust where there was only a 2hp increase at 73,000 miles

WOW N6600 is way off here. Going single or larger diameter reduces back pressure. You don't want more pressure with an exhaust. The point of upgrading an exhaust is to reduce restrictions(back pressure). The HKS doesn't really give gains as it is smaller diameter than the stock exhaust. Is mostly for looks and sound especially. Going single 70mm exhaust is where the most gains will be gotten.

Sounds good!

I only had the car a few days before I put that exhaust on. I really didn't notice a HP gain, those motors are already tuned so much it's hard to get more power out short of FI.

Hey did you feel any hp gain from that exhaust?

[N6600]

dude, try removing one of the exhaust, i noticed it can produce more power and back presure.

[KajiDrifter]

Produce more backpressure? Uhhh.. I think the point of the HKS Hi-Power or any aftermarket exhaust is to REDUCE back pressure. :)

[N6600]

i really couldn't expalin it in detail dude, im no mechanic, i just felt it, especially the back preasure thing. sorry. however, i put it this way. i consider the dual pipe as one big pipe. take away one, and all the engine's thrust concentrate on just that on pipe, very similar to your garden hose if you block half of its end with your finger. you would notice the presure gain.

For a turbo car some backpressure is good but with a natural aspirated car the less back pressure the better response and the more power.

[Recruit555]

other way around. backpressure gives you low end torque. a bigger exhaust will give you better top end but you lose low end. F/i cars need to breathe better. Thats why they get 2.5 or 3 inch diameter cat backs rather then n/a which usually gets 2.25 or 2.5 to the most

[segovian]

Backpressure is important up to a point. Imagine trying to suck through a really wide straw or a really small straw. It's hard isn't it? You need the correct diameter to get the most out of it. As it is, the s2000 comes highly tuned from the factory, how do you think Honda engineers achieved 120hp/litre?

[FinalBossWTMN]

You're talking as if you think the backpressure coming out is pushing your car forwards...

[slimshadymike]

sounds good!
