JonOfScio Posted February 24, 2004 Share Posted February 24, 2004 long story short, there are metal chunks inside flying around... hehe. Can I possibly pull off the manifold and punch it out? And would my O2 sensor work correctly without the cat? would it *harm* the functioning of my car? anyhow, I would like to replace the manifold with a header, but you know, that costs money, and I'm poor.

Legacy777 Posted February 24, 2004 Share Posted February 24, 2004 You can remove the manifold and punch it out. make sure to remove the O2 sensor before you do so, not to damage it. As for the O2 functioning correctly, yes it will, readings from the O2 are done pre-catalyst, unless it's the O2 sensor behind the last cat to measure catalytic converter efficiency.

JonOfScio Posted February 25, 2004 Author Share Posted February 25, 2004 Mudrat down in euge said he'd make up a front Y pipe header for $100. Sounds good to me. I'm sure he does good work, I've never heard anybody complain... It won't be a really awesomely tuned header, but 1) it will be better than what I've got, 2) won't cost an arm and a leg, 3) is less than the OEM one, 4) is better than screwing with my car and trying to punch the cat out all day.
