Mr2 Roadster (Spyder) Pre-Cat Removal - Part 1 

Not at all, enjoy your Mr2 - they're brilliant cars! Check out the Facebook group UK Mr2 Roadsters - really informative and helpful group.

Yeah the bolts can be a nightmare. Haha perfect reason to upgrade exhaust! 👌🏼

😵😵. You putting a 1zz in or 2zz 🤔

@@HimiJ just gonna stick 1zz in for the sake of insurance

Makes sense, fuel economy is very good as well.

I heard that MR2s have the pre cat fix if they were built in 2002...that is when the 2003 model year started but some pre facelift cars were built in 2002 as well. I am just wondering since mine is a built in 2002 2002 model year instead of a built in 2001 2002 model year. Any definitive evidence on if it was fixed or not on these final pre facelift units would be appreciated. The facelift 2003 models started production in 2002 for clarity.

@@fortheloveofnoise Just a heads up, whilst the piston rings were updated to make them less likely to fail on the facelifted model you can still experience engine death due to the precats-I'd recommend taking them out anyways just for safety.

Awesome! Thank you!

🙏🏼

Confusing times we live in

Yes, main Cat is still in place - pre-cats are only put in so the car is clean while the main cat is heating up. As long as the main cats heated up will pass.

@@HimiJ that is very good news! I'm on the verge of getting a particular MR2 and it's had a different stainless precat exhaust fitted. Not precats on the car, just the normal catalytic converter.

Good to hear you got it sorted in the end Jim 👌🏼

Yes, mostly surface rust addressing it in a coming video.

If it’s clogged that is. Also are they the same in the fact they should measure hotter at their outlet than inlet?

Hi Jim, thanks for your comment, the bolts that hold the cat to the manifold are known to be difficult to remove - they're known as the 3-amigos among Mr2 owners. It's normally a case of spraying them in some penetrating fluid, using a powerful impact gun or a breaker bar. Sometimes the studs come off with the bolt. A mechanic should be able to get them off 🤷🏽‍♂️, could be worth trying somewhere else. All the best.

Outside in my garden 😂

Milltek Sports cat will be going onto the Golf

I had the rear bumper off anyway. But shouldn't need to take it off to do this.

@@HimiJ Thanks! That was a really good guide. I"ll be watching this again when I'm doing this with my friends tomorrow.

Good luck. I posted a forum link in the description which has useful information and a step by step guide 👍🏼

Try cleaning the threads with a dremel or something Use penetrate stuff to clean up threads too Heat up the nuts and use bolt extractor sockets

Not sure if these are long enough, I'm going to try then today

You get it sorted in the end ?

Got you

@@HimiJ and me

Do it !!!

Did you?
