hmm .... as the title states, what are some specific differences between the two? I'm about to buy a single exhaust just because i'm getting it for a decent price, and it also had pretty nice reviews ... I don't know if I'm making the correct decision or not

it's mainly going to be weight and noise level.

^ Or how about the fact that singles usually make power and duals usually don't. Before anybody flames me, I will say that not all singles make power, and that some duals make power. However, all of the exhausts that gain a lot of power are singles. Who cares about the noise? Single exhausts sound amazing.

^Do blacked out tail lights make more power? Just busting your balls...

70mm single exhausts normally yield the most power

Money2536 - No, but the K&N sticker in my engine bay is good for 5whp. I hear type-R stickers are up to 15whp

"Powered by Honda" seatbelt pads yield the most at 25bhp

the s2k stock exhaust/cat back is not a real dual exhaust by design, the second muffler is not needed for the most part, i think most will agree it's more of a 34k car show piece.(inline 6 supra with 1000whp only running on one muffler)

if you going to get aftermarket exhaust, get the single if you don't mind the missing look, it's not as bad as ap2 bumper with the cut out.

power wise, consider this, moving air is a fluid motion, the more bends, twist, turns, split, you have the more restriction to the flow. There will be a power difference by design, and most of the dualie on the market are more show than pure power gain.(except for hks, i think)
