are open headers harmful? I installed my pacesetter ceramic coated long tubes a week ago. It has been open since then. It is loud, but i was pulled over a few days ago for my window tint and the cop didnt mention anything about the sound. I am pretty light on the throttle so i do not get a ticket for the sound.
It smells rich. I have heard that running rich burns the o2 sensors. how long are my o2's going to last? they are the bosch corvette PN 13111 sensors. I tried buying a foot long pipe extension for the collector to keep some of the open air away from the sensor.
Pretty much the only thing i am worried about is if this is harmful to the car? I will be getting TSP duals soon and a tune sometime after that.

Problem is the computer is miss reading the sensors because they are too close to the exit of the exhaust while your engine is firing its also sucking up small bits of air in the headers which is fooling the sensors. Take tubing and have that tube come off the open headers about one foot and you should be better. Also i would have the tube pointed down to sound better and to keep the heat, and fumes off the car.
EDIT: Sorry didn't read the hole thread - see that you have already tried that.

Not everybody has the O2 sensor problem, but the only thing you're really harming is the environment... But hey, if you were really that worried about it you would have bought a Prius 
Enjoy the noise!

To put it simple "Yes. They can be harmful." Long tubes are fine because they are far enough away that you wont harm your valves, shorties and mids are a completely different story. Like I said before, enjoy the noise lol

Like I said, you would know if your o2s were bad.
Yes, LTs are fine... If you want to replace 100$ worth of o2s every couple of weeks.

i ran open headers on my tahoe and my TA for 1 or 2 days each until the exaust shop opened up it made me grind my teeth every time i started it. its so loud i would never even run it that way at the track, i did have dual cut outs on my Y about a foot or so off the collector

It is almost like a backfire.. Just a gurgling kind of sound. It won't be a smooth pick up but more like cutting in and out. MPG will be complete **** and will run very rich.
