I thought 70 mm dual was too big for N.A ?

Why are you selling it man? anything else is going to be a downgrade.

AMUSE R1 DUAL!!!! FTW!!!!

Amuse and J's Racing both have a fantastic all titanium dual exhaust. Both lightweight and both produce some nice gains, not as much as a single, but PROVEN gains.

Invidia is one of the highest gaining duals out there and I have proof.

I have the fujisubo and I think it gained 1 or 2 whp combined with the test pipe. Its definitely nothing noticeable, but I picked up some HP on the dyno. Its either the intake, exhaust, or test pipe. Unfortunitly they were all done at once, but I was the second hightest N/A s2000 to dyno that day. There were a few other duals (Mugen, Skunk2, etc) and I dyno'ed higher than all of them. I did out-dyno an Invidia as well, but its an unfair comparission as it was an AP1.

Yeah, AP2s typically dyno 10hp, atleast, more.

FWIW, my AP1 (when it was NA) with K&N intake and invidia V2 + tp made the most horsepower my dyno operator has seen on any AP1 s2k by nearly 15hp.

You must be new to the boards! Rice abounds on many S2000's.

Singles look ghey on the S2K unless you come from the 16-23 yr old demographic who doesn't know what dual exhaust is. The OP doesn't care about singles anymore- he wants a dual. sadly, I just gave in to putting a single on(T1R 70RT) for weight reduction and minimal gain(1-2 hp) over the Invidia.

I have owned the V1 and V2 Invidia for the past 4 years. I know they make power over stock and save about 30lbs. They don't make earth-shattering gains, but they exist. There are quieter exhausts that gain a little as well.

i like the idea of a dual... but the motor is a four cylinder... its not like it has dual banks of cylinders...

but i am going back to stock exhaust for the time being... i loved the t1r single.. but it was way too loud for everyday stuff.... oh and im broke and need the money

I should clarify, none of the listed exhausts are "dual" exhausts. They are dual muffled exits. True dual exhausts have two separate(with the exception of an added "H" pipe) exhaust pipings- one for each header. The only way for a inline, single header setup to have a true dual exhaust is to have each half of the cylinders to have its own separate exhaust piping all the way until exit.

In the case of the S2000, it does not come with a dual exhaust, but with a dual muffler, dual outlet setup- the look of which I like. It reminds me of the good ol' days.
