When you do this just wash the honey comb material with water. This will prevent and asbestos particles being sniffed up by your nose. Yes you'll have to use a face mask as well.
Helped my best friend hollow out his precats and regular cat on his Spyder, sounded sorta weird after that though, had like metal tingy noise, he’s since swapped in a 2zz with a eBay 4-2-1 header for a lotus so currently he’s pie cutting the header runners at the flange to get the correct angle
Did it sound like a piece of ceramic rattling around? Probably a piece of that ceramic cat material. I want to try this on my matrix as it has this header cat.
I wish I had a mechanic inclined friend to help me with my mr2. Mechanic told me I had metal shavings in my oil. I parked it in fear of making it worse. I need to figure it out.
Good news is, the lab boys say the symptoms of asbestos poisoning show a median latency of forty-four point six years, so if you're thirty or older, you're laughing. Worst case scenario, you miss out on a few rounds of canasta.
The manifold sensors are before the pre-cats, so removing the pre-cats doesn't affect their readings. The third sensor is behind the main cat, and there should be no errors as long as the main cat is healthy.
right when I was talking with my brother on my b-day (yesterday) about getting one of these... and someone pointing out this particular problem with the MR2... I might just jump the gun and get one for real, tho I'll need to spare some cash because they're close to 3 grand over here where I'm from....
I’m looking to buy a 2003 model and it only has 50k miles. If I remove the pre cat material will I still be able to pass SMOG and avoid any engine codes?
50/50 but you want to do it anyway otherwise you WILL destroy your engine and end up with another engine installed without the material anyway. Also there's aftermarket exhaust systems that pass smog I belive
I life in germany, you cant gut the precat here, you have to have papers for your car and safety check (very annoying paper stuff) I want to get the facelift model. 1. Does anyone know if the problem got fixed 2. Is there any other way then gutting it or switching motors
@@RedlineRicerhow did they hold up? Did you go oem? My biggest question is does this cause codes? I have this manifold cat on my awd matrix and I think and hope it’s what is causing issues. Was measuring 100 deg warmer at the front of the cat vs at the outlet
Not really. I dont know much about kalofornian tests.. But here in germany where all things emission related are handled pretty strict too it would not matter because pre cats are only really usefull while the car is cold, tests however are done when the car has warmed up. There is somewhat of a deviation but here its within tolerances.
It would pass fine as it still has the normal cat, these precats were just Toyota being overly cautious, with the normal cat it will have normal car emissions.
If the cats have asbestos in them then you should be really really careful as if you get it in your lungs 🫁 it will kill you and you need to dispose of it very carefully.
This is a very unpopular opinion but it is not the precat getting sucked back into the engine. Since the mr2 does not have egr (exhaust gas recirculation) Bits of the catalytic converter will just be bloßen out the back. According to professional mechanics the trouble is rather caused by sticky piston rings refusing to extend out because of cracked oil, resulting in increased oil consumption as it will enter the comustion chamber and be burned and decreasing power as the engine can not use the Explosion in the cylinder effectively due to blow off. There are additives to remove the coal from tight spaces that May help. Most importantly is to keep an eye on well lubricating the engine. The engine can still fail in the mr2 even though the precat Has been removed.
@@19marth nice dude. Some guy want to trade me a 2001 with 164k miles for my motorcycle. I’m considering it but I’m worried about issues since I don’t know the reliability of this car

Did you get it fixed
he answered all i was looking for
Thanks for posting. That junk is creepy. Bout to change out my original header w an OBX- r w straight pipe to lotus style muffler.
welcome *BACK* to you too xD
I don't want to mess with asbestos. It's a very hazardous material. I'll just replace the whole part with a new one.
Good news is, the lab boys say the symptoms of asbestos poisoning show a median latency of forty-four point six years, so if you're thirty or older, you're laughing. Worst case scenario, you miss out on a few rounds of canasta.
Dont you have problems with the oxygen sensors ? dont u have fault engine code ?
The manifold sensors are before the pre-cats, so removing the pre-cats doesn't affect their readings. The third sensor is behind the main cat, and there should be no errors as long as the main cat is healthy.
@@citrusjuiceboxhope it’s the same on my matrix
Excellent video! Do you know if 2006 models have the same problem with the pre-cats???
Usually only earlier models. But I would get rid of it anyways. Save your motor. No check engine light either
Nice video!!
Ey so it’s been about 4 years how is the car running now with the pre cats gutted any issues?
I wanted to remove those stuff from the pre-car too. Will the check engine light comes on once you put o2 sensor back on?
Mine never did.
Mine did after gutting precats.

Quick question? Does the 2003 model have the same problem?
Dan Nguyen yes
Dan Nguyen from what I have read it is less common in the 2003 and later years.
@T E it's not really the piston rings, but the pistons didn't have sufficient holes number or holes or they were too tiny for the oil to be picked up.

UlyRosales yes!

do you get a check engine light after u gut the precat ? since the temperature before and after the precat is now the same.
This is a good question.
Nope
@@RedlineRicerno 02 spacers/anti-fouler or a tune needed for it to not throw code?
How often will have to you inspect/ gut the pre cats?
If you have a pre facelift model I would do it right away
Is it a guarantee that engine will fail with pre cats!?? I have a 2002 Spyder with 197k but it still runs strong .
Yes
Yes
have you done it to the main catalytic too or just the pre cat ?
phone roni main cat is fine. But if u watch my recent vid, I just did a Catless downpipe so yea I replaced it
Is this just on spyders or also earlier models??
How was the sound after pre cat remove;
What do you do when an Mr2 is consuming so much oil? You change the oil today, next week is less than half. Any ideas anyone?
The 1zz have oil burning issues. If it’s going through that much start saving up for another 1zz or swap for a different motor
@@RedlineRicer Thanks for your reply.
I wonder how this would effect a smog check..as in would it still pass emissions? I'm guessing you don't live in California.

does it pass MOT after you did it ?
Thats what i´m asking me as well.
Where did you get those canards if you don’t mind me asking
add w1. i can maybe send some to you. they are my sponsor
Redline Ricer is that a IG? Where do I add?

Do you have a fault engine code after doing this

Big question what year is your mr2?
Char Aznablest 2000 so of course with all the problems
Redline Ricer thanks!
um isnt breaathing in asbestos really terrible for you and can cause early death quite easily?
180k on an mr2, dang! Lol
Mines got 240k and running perfect
