TODA exhaust: excessive drone?

TODA exhaust: excessive drone?
OK here's the thing: I bought Mighty Wokka's full TODA exhaust (manifold, resonated test pipe, cat back). I knew there would be some droning, but hey, no pain no gain right? wrong! I find it to be excessively loud inside the car, at very low frequencies... yes, droning. I can actually have a pretty normal conversation with my passenger, so the drone is truely only a deep resonation.
Currently I have the test pipe and the cat back installed. I'm told I need to get the manifold on there, that that will change the exhaust note, which might help a lot. But I'm not convinced on a manifold killing the drone.
Most irritating about it is, it's between 2500 and 3500 rpm, daily driving territory. If it was over 5000rpm or so, I could care less.
Now I know there's people in the UK with this exhaust. Could you please chime in with your experiences? Maybe I need to resell the exhaust, maybe I need to make a few simple adjustments and be happy after all.
(I want to keep it really. Awesome exhaust note in VTEC where I don't mind it being crazy loud and the looks are exactly what I want from an exhaust)

what did you move to it from?
When I first put the H&S on mine, I had decided within a day that it had to go.
I kept it, and now I hardly notice.
...that's not to say that passengers don't

from stock, but I've had excessive exhausts in the past on different cars (Integra R, CRX VT) and none were THIS bad. I don't mind a little, but I'm experiencing excessive drone now and THAT is what I want to get rid of.
This is no longer a 'get used to it' drone!

I guess you might as well fit the manifold and see what happens, as it's a good bit of kit and certainly shouldn't increase the noise.
I have a J's manifold and decat with stock exhaust and doens't make it any louder.

Hmm... do you have a silencer? My spoon (single) is annoying without the silencer. If I drive say 30mins without it, it will certainly have an effect on my mood later, lol. Don't recommend it for daily driving. However, with the silencer it is a LOT better. I am not even sure if I notice the power loss. Perception of any change is harder to discern because the sound also changed.

IMO a manifold won't change it too much, it's the noise
from the exhaust - the exhaust gases velocity and resonance point of the car/design of the exhaust diameter and silencers.
The S does have a resonance point between 3-4k rpm that's masked well with the stock exhaust due to the CAT, helm holt resonator, twin loop system inside the backboxes and piping size/material.
Putting on an aftermarket exhaust you get rid of most of these things in the name of performance. Having an intake may help slighlty.
I have a quiet single 5zigen, even that has a little drone but not much.
So you either have the performance (very little with duals) or have a quiet exhaust with no gains but lightier or a halfway house.
I'd try the manifold.
