Default best cat placement

Im about to buy a catless downpipe and make my own exhaust system. I plan on running a straight through magniflow muffler in the midpipe and 3in straight back that splits into two sorta like stock. Is it better to buy a catted downpipe or put a cat between the muffler in the midpipe and downpipe? Or should i just forget the pipe?

Do you want the catalyst to perform actual conversion or are you merely trying to appear emissions compliant?

nah seriously tho .......im in northern mississippi and never seen or heard of a inspection station anywhere close, We pay 5 dollars a year for a State Insp sticker...all they do is make sure your headlights,turn signals and horn work.
We got dumbasses runnin around with open downpipes and **** lol
The state just isnt concerned with the issue i guess.

I've never gotten a sniffer test in New York, I don't understand why people keep asking me what I do about inspections without a cat. I say I pay the man and I'm good to go. There's not even any garages around here that have a sniffer. Hooray for a part of the northeast more akin to the deep south.

put the cat right after the downpipe, then make a straight pipe matching the cat length. make it easy to change and you have a test pipe for full time use, and a cat for sniffer time.
