Heat under passenger floor

Is it normal to have the floor on the passenger side heat up? My buddy brought it up yesterday while driving back from some trail rides.

Your cat may be getting ready to go out. The CAT Is right under the passenger so not surprised if you feel the heat. Especially if you have aftermarket exhaust.

It will start running bad if it starts to clog.

Loss of power and more heat.

I wasn't trying to be a wise ass when I made that comment. It's just that if the cat really starts going its going feel like your baby is choking. Good or bad I know you have an attachment to your ride so you would just naturally do what you know you have to do. Easy call

I have no experience with Flowmaster cats or know if they even make them but as far as sound....I put a Flowmaster 40 muffler on mine two weeks ago (I have no cat) and I am very pleased with the new growl. Just one of those mods that happily surprises you

Are you kidding? Are there any YJ's in Florida that do have cats?

I really can't think of any. The air flow will be better which should increase the performance and power even if only slightly. That said, and this is just my two week experience speaking, my mileage has increased 2MPG since I threw on the new muffler which definitely has a better air flow. Lastly, because weather in the US travels from the west to the east....any additional pollution created by your selfish behavior in removing a federally mandated part (lol) will blow out to sea. Believe me Nemo doesn't give a

So is that the culprit for sure everyone is thinking? I'm beginning to have the same issue as well as my friend. Just a little to the right of the tranny it's getting pretty warm to the touch.

I've noticed mine also getting a bit hot, but more concerned with the RPM's staying up after a drive or between stop lights. Doesn't happen on first start up though, would this possibly be an issue with a bad cat? Also getting some spit out of the tail pipe. After you remove the cats is it also recommended to get a new O2 sensor?

Just to pose a different idea there is no heat shielding on the tub where the cat is installed you could put some there and should see a dramatic decrease in floor board heat and while you are at it put some on the gas tank where the exhaust pipe runs should keep it from melting on the trails as it bounces around assuming you have a plastic tank like me.

For those in hippie states

My 89 still had an upper heat shield one if the dew things standard on a base model.

So when I did the exhaust I cleaned all the dirt off and have no heat issues.

If you fab things or have sheet metal guy handy you could make something to go above. Or you can just put some heat reflecting pads on the floor like I used dynamite or an equivalent when I put the (wife's) carpet in.

Takes some noise and some heat out.

I would really check this melting condition out ASAP. Unfortunately I know from first hand experience this could get serious. A long time ago ( in my misspent youth) I had an 82 corvette stuck in the snow. Being a semi-lunatic I slammed it back and forth so hard trying to get it out the cat glowed cherry red and poof. By the time the fire department arrived it had completely melted.

I wish I would have chopped the cat off the vett Florida has no emissions test. If you don't need it to pass in PA I say cut it off for sure

I will. Would there be anything else to look at or consider for a 2.5? Should I change the 02 sensor also? Thank you for the recommendation.

Maybe this question isnt above your pay grade - will the O2 sensor malfunction if you remove the cat and the rest of the exhaust and just have the downpipe that dumps the exhaust after the exhaust manifold? Or is everyone advising replacing the cat with a straight pipe?
