so i just went out and bought a cat convertor for my 93 cherokee just because it sooooo loud in my jeep i cant think straight. i swear if u road in my jeep and u were trying to talk to me i wouldnt hear u unless u were screaming lol but all the holes in the floor doesn't help any i guess, but any ways do i have to have o2 sensors on it or not im curious. btw i have a dynomax muffler with no tailpipe.

 

should take the dyno max muffler off and put a stock muffler on it, then it wouldnt of been so loud. yes you need o2 sensors or it will throw the computer off.

 

I'm not understanding the problem....

 

rly even being a '93?? hmmm cuz i took a look under the jeep and their is no wires hanging anywhere around where the old cat was

 

just wondering if i need a o2 sensor when i put on my cat.... i bought the jeep and all it had was a straight pipe from the header all the way to the old muffler

 

i would add a pipe to that exhaust to take the fumes from undernieth and to possible move the sound further back. My o2 sensor is attatch right after the cat i believe, its raining out so i wont go check lol. But yea 2 o2 sensors.

 

yes even being a 93. there prolly isnt any wires from the previous owner installing the straight pipe and cutting out the old 02 sensor wires.

 

ok thanks cuz i guess i need to find where the wires for the o2 sensor are.. im kinda new to cherokees i bought this one last month( my first one) so any advise is greatly appreciated. btw i love my jeep :-)

 

crap i swear i hate the previous owner GGrrrr. thank god i only bought it for $400 sweet deal i had to replace soooo many parts right now its not funny but thank god also i work at a scrap yard and every part i get is FREE.

 

I believe OBD-I ('95 & earlier) have only 1 O2 sensor, in the exhaust beside the motor.

 

I have a 93 there isn't a censor by the cat, cat should be under passenger seat literally right behind the crossmember that supports like the transmission, should be about a foot of pipe and then the muffler that should be under back seat this is all on passenger side hope this helps

 

thank you ur info helped alot. i just went out and took a look and where the header pipes connected to the downpipe to the cat their is a o2 like 6 inches below where the 2 bolt together.so according to ur info where the cat is sopposed to be by the crossmember for thr transmission the preveious owner put the muffler there, so that means i gotta buy a short pipe so i can move the muffler back some more.

 

yes it does, thank you i went out and found it

 

Glad I helped I hope it gets fixed soon cuz I have herd that in some states its like a $10,000 fine if u don't have a cat

 

ouch!!! well im glad im putting it in this weekend, cuz monday morning when it was snowing i was doin 4wd donuts in a bar parking lot like 2 1/2 blocks away from my house and my dad hear the muffler when he was in the kitchen watchin t.v lmao.. but i'll take a video tomorrow so u guys can hear what it sounds like, i'll upload it to youtube... my screenname on youtube is the same as here 1993jeepcherokee i have one video already up
