No, no, no... it is clearly a restictive portion of the exhuast. I do NOT doubt that at all, I never have. What I am saying is that it is likely not "the" bottle neck, or in other words, not the single most restrictive portion of the stock exhaust system. Meaning there can only be one bottle neck in the system at one given time. I am of the opinion that the cats (both the pres and mains) as well as the Y-pipe joint are probably more restictive than the resonator. Therefore, my position is why remove the resonator when it is not the part (on a stock exhaust system) that is slowing down the gas flow. For example, if 50 widgets of gas can pass through the cats in one second, and 60 widgets can pass through the resonator in one second, removing the resonator will still only allow 50 widgets a second to exit the exhaust system...
first I swear I read that you said your experience is with other 4 cyl cars, and it is obvious that this isn't and many people in the know have replied
i think you missed the fact that the loss is addative, well there are losses from all the parts of the exhaust, but if you remove a part of the sum of losses, no matter how little the total loss will decrease, so it make some sence to remove the resonator, not only from a flow point but a sound stand point
again many have said that the resonator has a much smaller diameter then the rest of the exhaust and the other exhaust components are not as bad, this means the resonator is going to effect the flow also
I also think you missed the point made about people who don't or can't change the rest of the exhaust, changing the resonator will net a little difference letting the exhaust flow better, and since it is easily done more people can do that
