I am amazed at the number of obviously salt-damaged undercarriage components you see down there. Guess it must be all those folks from the NorthEast that move down to Central & South FL.
"You're not allowed to do that" . . . 😂😂😂. Especially if you are silly enough to take the truck to a business after you cut the cats off and replaced them with straight pipes.
Things never happen when I take things to a mechanic. Funny story. I could feel a vibration in a brand new work van. Our mechanic could not feel it. He was thin, I'm over weight. I told him to find a fat mechanic to feel it. LOL
You can still use all 4-O2 Sensors even tho Cat's are Gone, people in my neck of the woods do it all the time, one upstream of Mufflers and one Downstream and when warm they will allow engine to go close loop for Gas Efficiency. As already mentioned, the oil burning engine probably plugged/burned out Cat's….
My first wife's father was a mechanic and she had a '78 Ford Granada with the 300 inline 6. He had removed the cat and the car had the performance of a one legged man in a foot race. I had a '76 Granada with the same engine and trans and could run circles around her. After we got married I put a cat back on her car and put things back to specs. Everyone thought he was going to kill me (twice my size). He was pissed but shut up after driving it. This was back in '85.
Here in the upper peninsula of Michigan there is no inspection's or emissions. There is a lot of vehicles running around without catalytic converters. Of course most people take them out themselves. Never herd of anyone getting a ticket for not having one here. Of course most cops when pulled over won't check to see what you have for a exhaust system. I got stopped once for a loud exhaust the cop asked what kind of muffler I had and I told him non. Wasn't told to fix it so it stayed that way until I got rid of the truck. It was a 96 Silverado with the 350 and man was it loud. It did have a full exhaust system also just no muffler.
that tail pipe needs the coat hanger wire, bailing wire isn't robust enough for exhaust components, best to stab a couple holes through the trunk floor with a screwdriver and wire it up through there, get you're 700 bucks and move out of town
Removing the cats is f'ing stupid! If you want to improve exhaust flow, spring for high flow cats then! The biggest reason engines last WAY longer than they used to is electronic fuel injection and engine management because it doesn't wash the rings out like carburetors always did. Forcing it to run in open loop will always make it run worse because the computer can't accurately determine if the mixture is correct or not, which forces it to run rich to avoid the engine damage than can potentially happen if you run it lean. Cutting the cats off may have helped the old carbureted cars on the late 1970's run better (they weren't computer controlled at all) but will make computer controlled vehicles run worse unless you reflash the ECU to run on an upstream O2 sensor only. STILL not worth it!
Open Loop is electronic-speak for the equivalent of the choke still being on/stuck on a car with carbs. I had an old Buick with carbs that did this and also got terrible gas mileage. $1200 in smog B.S. later and a new cat (old one was clogged pretty bad/effectively had no cats) it drove, well, like an 80s Buick again. Hated that car… It's amazing to see that technology has hardly changed – and why I don't buy Chrysler or GM.
Is it actually still unlawful in Florida? I just went through a state inspection licensing in my state and i heard you guys don’t because your emissions are so good
They should've put the rear 02 sensors in it probably wouldnt have a check engine light on I had a 2007 chevy truck with a 4.8 v8 and my cats started rattling and I gutted the cats and it looked like it still had cats but they were empty and I had not check engine light on and it ran better then it ever did and my truck had 250000 and had no problems.
That was stupid. Everybody knows that if you delete the cats, you install the downstream 02 sensor on top of an anti fouler (wherever you want on the exhaust). That way, it will always read CAT efficiency at 100%. It's also a great, cheap ($80) way to get rid of the engine light if you have a bad CAT. Just remove downstream sensor(s), put a 90⁰ anti fouler, put the sensor(s) back on top of it, and off you go. Did this 6 years ago and the light never came back.
So what happens to the Shop that gives back a Vehicle with the SRS light on and said Vehicle is in a accident and the Airbags and Pretensioners don't deploy?
Yuck. When I did a stint at a CDJ dealer, they had a metal cab full of rods, pistons, ring sets and gaskets. I tore down 6 or 7 in a 1 year period, pistons out of round, bores with massive taper, just worn the F out. None of them had 150K miles. And head gasket blowing. Oohh the headgasket blowing.
That law is now in Canada ! Honest your Honor , my friend’s friend just fixed my noisey exhaust ,an invoice you say, oh no he saved me the tax money if I paid cash! OOPS ! LOL
When they're covid backordered well sorry about your luck…been waiting since November '21 for new ones for my ram 1500 and I'm about to that very thing to restore engine rpm with out making the torque converter stick and keep wanting to pull when I stop
I may have missed your background video – How many years have you been practicing, learning, working on cars, sir? WIth much a do respect. Because I am no where near your experience.
I went to an exhaust shop and they asked me if I wanted cats removed. No idea why I had no check engine lights or drive issues at all. So they must do a lot of illegal removals
I like the way the customer says " Some guy did it at his shop" Like the customer did not tell him to do it. No sane shop would have done this. either the owner did it or paid some guy to do it. Somebody has got some 'SPLAING to do!!!!!!
My brother had a Dakota just like that (his had the cats) .. about same mileage however completely rotted out underneath, was junk!.. Pennsylvania roads and salt will do that.
Such a newbie move. When deleting the cats you still have to put the downstream O2 sensors in and then remap the system. Once it is done you're good to go.
Add a comment…

i own the same truck and its been a total pos contact me and ill give it to you for free
at the end… I can't believe how much rust was on the 90s chevy… wow…
You got to the bottom of the problem.
Weight reduction. LoL
Things never happen when I take things to a mechanic.
Funny story. I could feel a vibration in a brand new work van. Our mechanic could not feel it. He was thin, I'm over weight. I told him to find a fat mechanic to feel it. LOL
I don't have any cats and I don't have a check engine light or anything. I think there are defoulers or something. I forget.
Cant wait to get rid of my cat when it goes out
catalytic converter are often stolen, there's good money from them.
Did you get the vehicle for the customer states portion from Eric O? 😏 That weight reduction looks northern.
Soon as you read those codes, I knew what you were gonna find.
Serial EPA offenders risk federal prison, so says the Clean Air Act.

Nice work ray
The diagnosis are so educational.

I learned a new word today. "normular" 😂😅🤣
Haha i did the coat hanger trick one time out on the highway….didn't fix it properly for a while and eventually the hanger rusted out.

I think you should work on a Lamborghini…
Lol i can't believe some one actually cut out the cat's..

When you said 181k on the clock I almost spit my beer out. Those 4.7s are legendary for lifting heads from overheating issues.

removing emmisions stuff for like 4 hp at most lol

I had that truck and when it was running fine I only got 10mpg.
So what happens to the Shop that gives back a Vehicle with the SRS light on and said Vehicle is in a accident and the Airbags and Pretensioners don't deploy?
very interesting – super vid. Interesting all they did was the cat delete and basically nothing else, whats the point other than to spew pollution?
lol she's seen better days

Enjoyed your vids new scriber!

folks are so dumb these days thinking these cars can run without cats and get power.
Almost Pro Stock??? LMFAO

My brother had a Dakota just like that (his had the cats) .. about same mileage however completely rotted out underneath, was junk!.. Pennsylvania roads and salt will do that.
not illegal in Oklahoma
all the oil burning killed the cat..
I had the dakota with the magnum engine and it was very fast compared to my 80s f150 with the 5.0 L

A tune and it'll work fine
