Flex Pipe Question

Flex Pipe Question
So now that my starter is fixed and everything seems to be running smoothly I am going to get rid of my rattling cat. Question is I don't want a cat anymore and was wondering if anyone knows anything about Flex pipes?

This is what I am thinking in place of the cat. It is stainless and straight through...which should be great for when I slap my new muffler on for sound.
Any thoughts on this?

I've read a lot of people do exhaust work and just tie the 2nd O2 up onto the frame and never get any CEL's because of it. I will be leaving both of them right where they are, Just going to cut right at both ends of the Cat.
A lot of cars that I have worked on have flex pipes just like the one I'm interested in to cut back on exhaust rattle. I am really feeling this for simplicity sake...
Also where I live there is no testing, so I am golden!

Well its either a flex pipe or just a straight pipe where the cat used to be...
Why is everyone so against the flex pipe though? Straight pipe is similar to a flex pipe, plus for people that have hollowed out their cats you would have noticed a difference in performance and noise I am sure?
Now I'm not looking for a real performance boost, just ease of instalation and to keep cost down. $25-$30 for me to install a flex pipe vs $150 to have someone weld up a new cat...Doesn't that seem intelligent for those that don't need to do emissions?

Back in the '70's, I had a custom van that I put side exhaust on. To connect the headers to the side pipes, they used flex pipe. It burned through within 6 months. I replaced the flex with solid pipe and didn't have any more problems. It might be cheaper at first, but then add in the expense to redo it again in a few months.
