So I Changed the Whole Exhaust Pipes with 2" and Removed the Three Filters (the Cat, the "Y" and the Muffler) instead of Muffler my Subies got an Empty Can, but Filled with Fiberglass Noise & Heat isolating (industrial Grade) Compound, so it Won`t be a Fartcan...

Yep - that's why I always gut them.
I have the means to cut one open and gut it and weld it closed..
(I own a mig welder and a cutting wheel)
Is this the best way to do it??

If youre going to cut it open and gut it, remove the exhaust and do it from the top, so IF you do have to get an inspection it wont be noticed. Cutting and opening is the best way to make sure you got it all out.
As far as gas mileage goes, I don't know. I dont have a fuel gauge or a properly working odometer yet. GD would know.

I always cut about a 6" sqaure out of the cat on the top, gut the internals, then weld the flap back on. It's all hidden under the heat sheild and they weld real nice as they are stainless.

and i dont want this to evolve into a backpressure debate.

If you think you might be down on mileage and can't find any other reasons - it's worth a look inside the cat. I picked up about 3 MPG when I opened up the cat on my '83 hatch. The contents were completely gone and the metal brackets and mesh screen were wadded up in the outlet. Bumped me up to 26 MPG from about 23 (engine has a low comp. cylinder).
