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

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?

step hardly on the gas ,PUSSIES

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

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

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

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.
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.

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.
