Is it okay to run with open headers for a while?
Is it okay to run with open headers for a while? will it hurt anything to run the open LT headers for a few days to a few weeks or so?
I need to take my duals off for a bit. So will it hurt anything?

If you have to do it, these are the conditions, though I would not recommend doing it for long or at all for that matter. LS1 Tech Stories

I did it for like a week, and that was the shittiest week I've ever been through in my life. Besides how loud it is, one of my o2's got screwed up, and I didn't have my laptop for that whole week, so I couldn't even adjust for any kind of fuel trims. Not to mention people would cover their ears when I drove by, and all my neighbors were pissed off at me even when I would idle through the neighborhood.
Pluss if it is cold out, after you shut the engine down, if cold air gets up the headers at a fast rate, it may crack or worp a valve. Example, if it is windy out and dumb luck has it the wind is actually blowing into the collectors.

I ran open y-pipe for a while because the bolts on my I-pipe to y-pipe connection kept coming loose. While it was open I would average around 200 miles to a tank and driving the car just sucked unless you had it floored. Got everything bolted back together, and boom. It was like I was driving a completly different car. I could easily get 300 miles to a tank, and its part throttle manners were a lot better. In other words, I wouldnt do it unless you had to.

This is no joke. I rolled open headers on my truck for a day while waiting for my y-pipe and it was extremely loud. Every time I pulled up to a stop light, I would be next to someone about 90 years old. Damn they can give some shitty looks. lol. But yes, significantly worse gas mileage and you do run the risk of valve damage. I would go very easy on it, resist the temptation of a WOT run with open headers.
Oh yeah, it is a good idea to unplug the O2's if you are going to run open headers. Goes back to what the other guy said about dumping a lot of fuel and it will cause it to smoke like a bitch. Plus removing the O2's will improve the idle and overall driveability a bit. But its still going to be tough.

So what's the point of cut-outs then? Wouldn't that be the same thing? I see folks with cut-outs just past the headers on the y-pipe. I've never heard of them having any problems. But then again, I don't know JACK about exhaust evacuation. I am running through my cut-out right now, but it is back on the I pipe just behind the passenger seat. It is loud, but the performance difference is ten fold and I get better gas mileage. I guess it's all in where the gas is going to escape.
