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.

The Silver Gorilla 07-30-2013 09:01 PM

stock exhaust. Sl lets just say the CAT goes out, what would happen?

Cashcrazy 07-30-2013 09:14 PM

It will start running bad if it starts to clog.

jokerchief462 07-30-2013 09:14 PM

Loss of power and more heat.

87 Florida YJ 07-30-2013 09:38 PM

You will immediately replace the cat.

The Silver Gorilla 07-30-2013 09:47 PM

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:rofl:

Well one silver one haha, are there cons to doing so. Id rather not pay $100+ if i can just take it off.

AllMudd 07-30-2013 10:17 PM

Take it off! I wish I could. Damn hippies!

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

Love this!

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.

Same issue as me buddy

1987Wrangler YJ 07-30-2013 11:53 PM

my floors as getting so hot that the rubber seals are starting to melt. I guess my cats bad too! lol

crabman141 07-31-2013 09:35 AM

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?

89Saharagreen 07-31-2013 10:18 AM

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

Chief

jokerchief462 07-31-2013 10:38 AM

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.

hooray fiberglass!

1987Wrangler YJ 07-31-2013 12:04 PM

Really?! I was going to chop that cat off anyways My jeep has a 3 inch body lift and A heat shield on the bottom of the body

87 Florida YJ 07-31-2013 12:15 PM

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

crabman141 07-31-2013 12:39 PM

I think I'll cut mine off too, don't want problems down the road. Should replace the muffler to while down I'm there too.

Consider the Flowmaster 40 for fun

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.

87 Florida YJ 07-31-2013 01:41 PM

Sorry. Above my pay grade

petercass88 07-31-2013 03:03 PM

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?
