Catalytic Converter DIY??
 
i looked and didn't see a thread for replacing the catalytic converter. maybe i missed it.

anyone ever do this? i'm in FL so the BavAuto part would work for me.

Step 1: Cut out old ones.
Step 2: Weld in new ones.
Take it to a custom exhaust shop, let them put it in. I got both of mine installed for $100 which I recouped by selling the old ones to a recycler. Overhand blind welding is not easy, its best to let someone who does it all day long do it. Even if they are not a BMW specialist.

Do you enjoy working on rusty exhaust systems? If so, it's a remove/replace job.

Bear in mind, the I6 exhaust manifold bolts are, I believe, $21 apiece, so don't break them if you can help it. http://www.realoem.com/bmw/showparts...83&hg=11&fg=50

Pappa Bear, he has a six; different ballgame. The Bav Auto cats are an assembly, with the pipes attached.

No DIY in the bestlinks.

There is just this:
- DIY: Free Fix for LOOSE Catalytic Converter Shields
- Catalytic converter dissection photos
- What kills catalytic converters?
- Miller Remanufactured Catalytic Converters

I ask the OP to run a search and let us know better DIY links that pop up so the next person stands on his shoulders.

It would have been nice if the OP had gone through the catalytic converter threads to find the best to help others ... but nonetheless, I just wrote this up for the bestlinks.

- How to remove & replace a catalytic converter (1) & how to fix rattling cat shields (1) & P0420 codes related to cats (1) (2) (3) & cat autopsy photos (1) & what kills cats (1) & an EPA fact sheet on catalytic converter warranties (1)

We probably could use work on these - but since I've never worked on my cats, I don't have any personal knowledge of what is of interest to others in the future so that's what we have now.
