Hi,

I am kinda @#@# because my two pre-cat O2 sensor are destroyed due to the removal of my Fabspeed exhaust. When the shop removed the O2, they told me something was wrong since they were very difficult to remove. The two after the cats were easy and spins straight out of the whole. However, the 2 before cats were "melted" to the cat and once they were removed, the tread were all eaten and I cannot use them anymore.

Can someone tell me were I can buy them ? What is the bosh part number, can I get them at a local parts store ? The stealer here in canada want $398 CAD each.... crazy...

Thanks
Bo
