I have a 3" one off my car. Not sure on its efficiency and you'd need to weld it on (it was cut off) but it should be fine for a visual. Let me know if you're interested.

It's not "cut up", just cut off. The ends are clean cuts. You could have an exhaust shop weld a 3-bolt flange to the y-pipe and the catback. Then put a couple 3-bolt flanges on the cat and bolt it in. Also have them cut a piece of pipe the same length with a flange on each side so you can swap the cat out. I'll get you a pic if you want.

What's your email? I'll send you some pics.
You can get a new cat for pretty cheap, you might be better just doing that.
