Question High Flow cat pipe questions

It's that time of season again, the mod bug is attacking I do a little bit of modding every summer, and this summer I'm thinking of doing something about my restrictive catpipe and getting some struts. I already have STi springs and I opened the muffler and gutted it last summer, as well as made Williaty's intake and new plugs

Anyways, to start off, are the only 2 companies making high flow cats Stromung and Random Tech? If so, is Random tech really worth the extra $200 premium over Stromung?

Also, would it be difficult to make your own catpipe assuming you had these tools at your disposal: Mandril bender, Welder and appropriate piping? There is an exhaust shop not 4 minutes from my house, but I'm cheap and the old man has an industrial welder and access to a mandril bender. If I got my hands on an appropriate High Flow Cat, think I could mod me up a custom cat? Or is it a bad idea?

As for the high flow cat, if I got one that was correct diameter and made for....let's say a 200 HP car in stock trim, would that suffice? I'm going off of the thought 'More HP means more air' so the flow would be good I assume?

Thanks for any ideas
