I removed the resonator today. Barely no difference from a noise perspective. I only drove 15min in the city after that and EVIC gained 4mpg. I could be the cold weather and just me driving like an old men. I'll report later on the mileage.

Oups sorry. I gained .5L / 100km which should be around 2 mpg on highway driving (70-80mph). Sometimes it's closer of 4 mpg but to not disappoint anybody I'll say 2 mpg. I like it. Cheap mod.

I really don't understand how it can make such a big difference in mpg, it's not even really a muffler, it's a strait through resonator. Now I want mine gone.

I thought I threw 50$ away when I looked thru the muffler on the ground. (Straight thru no restriction in the ID..) It made a difference though.

in theory, a resonator simply reduces/eliminates sounds caused by resonation.

you folks should listen for noise at different speeds/rpms after removing the resonator.

It would be nice to see two tips out the back, one on each side, like a true dual exhaust setup.

it rumbles a little bit more (enough for the girlfriend to notice it) but nothing major. It's barely noticeable.

I routed CCV hose under the car straight to the rear end area and plugged side inlet on the intake sleeve today. I can feel the difference in power, breezing fresh air definitely helps too. I was even thinking of "Y" connecting it into exhaust line, close to the dredded resonator, but seems like too much work.

what have you used to plug the T to the intake manifold? Have you let the line heater connected?

Line heater is still there, I used wine cork on the other side of the CCV inlet hose that got to the inline heater. You can use your imagination, anything solid will work.

Not to open a can of worms but what if the crankcase was meant to be on a vaccum (coming from the intake) and now it's forced to flow and push by itself?

Nope, it is not supposed to. Older versions had crank gas simply vent under the engine, same still goes for large semi trucks and other heavy machinery.
