Fixing the BIGGEST Issue with the MR2 Spyder! | Pre-Cat Removal | Toyota MR2 Spyder 

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

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.

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.

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.

welcome *BACK* to you too xD

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

Dont you have problems with the oxygen sensors ? dont u have fault engine code ?

Excellent video! Do you know if 2006 models have the same problem with the pre-cats???

Ey so it’s been about 4 years how is the car running now with the pre cats gutted any issues?

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....

Nice video!!

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.

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?

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.

do you get a check engine light after u gut the precat ? since the temperature before and after the precat is now the same.

Quick question... did u need new header gaskets when installing it back on?

Is it a guarantee that engine will fail with pre cats!?? I have a 2002 Spyder with 197k but it still runs strong .

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?

have you done it to the main catalytic too or just the pre cat ?

Quick question? Does the 2003 model have the same problem?

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?

How often will have to you inspect/ gut the pre cats?

How was the sound after pre cat remove;

Is this just on spyders or also earlier models??

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 ?

Do you have a fault engine code after doing this

Where did you get those canards if you don’t mind me asking

Big question what year is your mr2?

um isnt breaathing in asbestos really terrible for you and can cause early death quite easily?

Does anyone know where I can get a left taillight for this car

180k on an mr2, dang! Lol
