just like the title says... kinda crappy pictures. It's hard to see the difference without sitting next to a stock o2 housing, but I took out quite a bit of material all the way through it. Not just at the openings. I also deburred it to help prevent cracking, sand blasted it being carefull not to get rid of the factory coating and gave it a fresh coat. No more nasty rust color. I'd like to get $60 plus $10 for shipping.
