, thank you for the info but on reviewing that exhaust that sounds like a fair number of people have droning issues. Would rather have a dual exhaust it possible and certainly one that does not drone

If you wanna hear drone, you should hear my current Kent Works titanium exhaust lol. But hey, its race spec, rare, and from the motherland. As far as drone go for EVS SSP exhaust, I would say out of all the exhaust Ive ran EVS SSP has none - to the least drone, and when I say least, I say least in 'resonance frequency'. When you change out parts of the exhaust, it changes this frequency in the pipes, which causes the exhaust to drone/buzz at certain RPM. All aftermarket exhaust (w/o side branch resonators) will give you a certain measurement of resonance frequency via material of pipe, length/size/diameter of piping. Whoever said they had drone issues with this exhaust probably: has something wrong with their exhaust, has very sensitive ears, or is delusional. If you want low drone, stick with your stock exhaust, or Fujitsubo Legalis.

Do you care about power at all on this car? If it's not a primary concern look for a used Mugen exhaust. It's easily one of the best sounding exhausts on the market and it has zero drone. It has such a unique and refined sound to it, it's one of my favorites. The exhaust piping is small, so you're not going to be gaining much if any horsepower, but the way it makes the car sound is more than worth it.

Make no mistake: ALL affordable aftermarket S2000 exhausts drone somewhere in the rpm range. I've not heard the $2000+ exhausts. 
The Invidia Q300 (their "quiet" exhaust) drones painfully in the 3000 - 4000 rpm range, right where I drive most of the time. This system lasted less than a month on my car last year due to the headaches (literally). You can probably pick up a discarded Q300 for $300-$400 but it's way too loud for me. The stanced Civic drivers at the high school loved it.
Some of us have recently fitted the and are very happy with the Tanabe Medalion Touring dual exhaust which on my car behind a Berk 63.5mm HFC has a small drone during deceleration around 2000 rpm and during cold idle. The rest of the time the exhaust is in the 93dBA sound level range, sounds particularity "gentlemanly aggressive" in VTEC, and idles in traffic with a subtle performance note. (Tanabe should be paying me commission! )

There's evidence I've seen that a 70mm HFC or "test pipe" is less efficient than the 63.5mm versions as it induces more dramatic pipe diameters into the system. The OEM header exit is something like 57mm and dumping the gasses into 70mm slows gas velocity. And then the exhaust after the HFC or TP further affects flow and velocity.
Fluid dynamics at work.
Pretty sure the Tanabe Medalion Touring exhaust is a nominal 60mm inside diameter until it splits into a pair of 50mm mufflers. Gas velocity is theoretically nearly constant thru the system. It doesn't slow down thru a 70mm section.
Also a reminder that the diameter of the pipe makes a poor comparison as it's the volume that counts. Assuming equal length and ignoring the constant Pi the comparison is the radius squared. Ignoring a lot more physics (!) the 22% larger capacity of the 70mm pipe will let the gas flow that much slower to get the same gas thru the system. Based on diameters the prediction is only 10%.
