Exhaust Question

[04SilverChevy]

Ok so I'm in the process of restoring an 85 C10 w/swapped 350.

Just got done putting the motor back together(head gaskets). I just picked up a cheap set of Summit headers. I wanted to go headers, header mufflers then dump it out right before the rear tires.

I got to talking to my buddy, and my inspection mechanic, says I'll need cats(grr). So to get to the point of this post, does anyone know of any place that sells cats that I can bolt right to the headers? Or am I going to have to get a flange welded on a hi-flo cat?

Any input would be great.
