How is that a federal offense? It's still a fully functional cat... Better if anything

I'm pretty sure it's totally legal to have a cat converter on your rig. Now, having a "different" one may not fly in states with inspections, I wouldn't know though.

I'd say find a 2.25 or 2.5 inch diameter cat and put it in there.

I forget where I read it. I thought it was in the OEM Tech sticky but it's not. Take it with a grain of salt, all I know is I read that it's illegal to install a used cat. But then again, who would know?

Installing a used cat is a federal offense. Also cats are not that much I got my 2.5" high flow from mudfrog for like $50

DieselD

I had no idea. Lol.

^THIS!!!!! Don't spend more than you have to. $40 for a high flow ceramic core cat, $65 for a higher flowing metallic core.

Yea the ones I have are damn close to new ad nj only checks to see you have one... ... So to me, free and no legal issues ( I only have a dynamax muffler so it's not loud at all verything else is stock) that's good enough I was just wondering if it would still flow the same ie: are there different types of cats I shouldn't use

Good luck finding a shop to install a used cat

I do all my own work cuz I work at a shop....so that's not an issue...

A brand new high flow cat is literally $40.
A used cat may be clogged. May have it's honeycomb all busted up. May not be high flow.
Just get a new one.

Yea but I'm broke... And I have one sitting in y toolbox already that's from a 2013 dodge that had 4900 miles on it

Tom95YJ

If it only has 49k miles there is a reason it was replaced

mr white

Probably put a high flow in or XXX.
If your stock cat is fine, I dont' know why you'd even bother with putting in another stock cat. Take that dodge cat to the scrap yard and get money. They are worth quite a bit.

Let the noob learn. When he puts a used one it and his jeep runs like crap it's not interfering with any of our schedules.
