Catalytic delete?

Hello everyone, i have a 2014 SR 4.6 and i live in a place where emissions are not a problem, my questio is, can i just remove the catalytics and get rid of them for good? Will the truck works normally after that?
Thank you!!

 

Contact Keith at @dirtydeeds and he'll be able to answer any of your questions regarding Tundra exhaust

 

Yes but you’ll throw codes and also why?

 

It’s illegal everywhere. And emissions are a problem everywhere.

 

Leave it alone. If you want something louder, get an exhaust system.

 

Is not for getting something lauder, actually i don't like lauder, it's just that it is a spensive thing that i want to get rid of it. I live in a very middle of tx countryside, also i don't care the CEL or any other codes regarding the catalytic, i just need to know if it will affect the engine, or if it will cause future problems to the truck.
But i really thanks and appreciate for all your comments guys.. i really do.

 

If you cut it off, it WILL get louder. It will stinks. It won't affect or cause engine issue. You will likely get worse gas mileage. Check engine light will be on all the time. If it ain't broken, leave it be. There's no reason to get rid of it because it is 1 expensive part. I still dont fully understand your reasoning for getting rid of it because it is "expensive". I can understand if all your cats were stolen and in it place you just add test pipes, straight tube, for cost. But if all are intact, why cut off?

 

True, you're right, I didn't explain myself well, sorry about that. About 2 years ago the CEL came on, and I took it to a shop to put a scanner, and it's because of the catalytic converters, I've been driving it like this for 2 years and I think it's time to change them because I don't want them to go clogged, so that's why I thought that instead of spending so much money on that, I could simply remove them, and see if removing them affected the engine or the operation of the truck in general.

 

Ok. If that's the case. Just have them remove and put straight pipe in it place if you dont care about the cel being on .

 

Thank you, so much!!!
What about remove all the sh1t inside of them and but them back but empty, and keeping the o2 sensor on it? Will that works too?

 

Cut the pipe behind the cat, take a pry bar or chunk of pipe, jam it in there and break up that media, then start the truck and floor it. Congrats your cats are now hollow and your truck sounds like ass.

 

Yes

 

Alright, thank y'all guys for your help. God bless u.

 

If you are experiencing a clogged/clogging catalytic converter, and your exhaust system is in good shape otherwise (I.e. not corroded), the catalyst core can “theoretically” be removed to restore exhaust flow.

if you add a “spark plug non-fouler” to get the downstream O2 sensor out of the exhaust stream, the check engine light will likely stay off.

of course all of this is illegal according to state and federal laws, thus not recommended. You would not experience and extra noise or performance benefit beyond restoring power to pre-clog levels.

 

Very interesting, so, when u said "Add" a spark plug, are u meaning to replace the O2 sensor and put a spark pug there instead?
Edited, i just Google it and my bad lol.. i didn't know what a spark pug non fouler was. Sorry.

 

Perhaps you could cut out the primary cats and replace with pipe and move the rear O2 sensors to after the 2nd set of cats. That could remove the likely faulty set of front cats and keep the CEL off. I thought I previously read they were the same front to back as far as their ability to keep the CEL off.

 

What was the code? Might just need new O2 sensors.

 

You are not adding a spark plug… a spark plug non-fouler spaces out the O2 sensor from the exhaust stream to fool the sensor into thinking the catalyst is doing its job. Otherwise, you’d get a P0420 and P0430 code for catalyst under efficiency.

Thank you!! So i will need 4 spark plugs, one for each o2 sensor, right?
Or just for the rear ones?

 

No Sr, i thought tha same but i replace the o2 sensors and still the same. I don't remember the code but i do know that it says something like" Catalyst converter bank 1 and 2 below threshold"... something like that

These are what you want

 

So i will only need to add the spark plugs to the O2 sensors that are between the catalytics? Only those 2 sensors?

 

Just the two downstream sensors… after the catalytic converter .

 

Very good, thanks!!

 

I’m a member on a couple other different forums. In the past there were a few times where a new member would show up asking how to circumvent either a DEQ or a DMV loophole. Well established members of the forum were willing to help out the brand new member with all the info that the new guy wanted to find out. Turned out though that the new member worked for the DEQ and the other new member worked for the DMV. It created a HUGE headache for all of us other members. If somebody wants to know how to do something federally illegal, let them find out from a different website.

 

Did it work

 

If I had no emissions in my town I’d simply cut them out. And turn the codes off within a tune and move along lol. No secondary cats here and high flow primaries with no emissions issues

 

I don't see any sense in what you say, in these forums people ask and others answer, if what they ask is illegal, that doesn't make the person who answers a criminal or doing something illegal, I mean there's nothing illegal in answering, if the one who asks does it it's under his own responsibility and then he's breaking the law. But I don't see any sense in what you say, for example if you ask me how to kill a person, and I answer you by shooting him in the head, does that make me a criminal or breaking the law? I don't think so, now if you do it then you do have a problem. The same goes for the rest. In this case I know that everything that they've told me I can do is illegal, they've even told me so. But whether I do it or not that's my problem, the one who would be doing something illegal is me, not everyone who has told me how to do it. In any case it's not my case.

 

The O2 spacer that I linked you to will act as a cat as far as the test is concerned. The decorative pipe is for if they want to inspect with a mirror.

 

Thank you!! Actually those decorative pipes are awesome. Lol. But like i said here where i live, this is not an emissions county. The inspections here are only for the lights, wipers, horn, those simple things. So that what you shared to me it's gonna works awesome.
Thank you!!
