Anybody in the forum removed their cats and installed an O2 sensor? Does it really work? Will it be reliable to use for a long time? Will an oxygen sensor simulator work on 525i msport e 60 bmw?
I'm planning to remove my catalytic converter to give me a bit of power increase in the least expensive way possible. I saw some articles that the O2 simulator works and is fairly cheap.
Thank you for your patience in reading this. I hope to hear from you guys soon. Best regards to you all.

Ehmmmm... You can't completely remove the cat. Why ?
You would be faster above 4k rpm (especially 5k), but below 4k rpm you would be slower than a 510i.
I removed the cat on my Mini Cooper S and in second gear, 2k rpm, I wasn't able to accelerate faster than a C3!! But from 5k to 7k it flew.
I reinstalled stock cat and the final solution I chose is a 100 or 200 cells cat: in some weeks I am going to install it.

When you say "it flew from 5K to 7K", does this mean it has better acceleration as compared to having your cats there at that rpm?
Just thinking a loud...If the power gains are significant, I am thinking of putting a Y pipe by-pass and an exhaust gate-valve to open at say 5K rpm...then I will still need the O2 sim. Then again might as well buy a similar 100 cell cat like you suggested.
Graci!

Thanks a lot for sharing. I really appreciate it.

Yes, it was astonishing: never been on track with the Mini, but I will as soon as possible. And I will reinstall the cat decat (now it is interchangeable with the stock cat)

Some say to insert the sensor but less than that it should, letting it a little more out.
On eBay a 100/200 cells cat isn't so expensive.
Bye and let us know!
Grazie!
Ciao!
