Running Open Headers

[HGFireHazard]

I have an appointment set for the rest of my exhaust on Monday first thing in the morning, but I have to drive around 8 or 9 miles to get to the place. Would it be safe to drive the car there without O2 sensors hooked up? He is going to extend the wiring there, otherwise I would do it myself (better off with a warranty). The backfire sounds like I'm shooting at people, and I had a police officer on my street the second time I came home, haha, no more driving until Monday.

It will just use the default fuel tables and set a CEL. For that short distance, don't worry about it, just be very easy on the gas. You never realize how loud the car is outside when you're in the drivers seat.

lol, when I did my h-pipe, I ran it through open headers for a few minutes (just ran it, not drove it) and the CEL never came on. That can't be good. I'd be more worried about the flames coming out of the collectors though. I had my friend rev the motor while I was looking under there at the headers, and seriously like 3" flames were shooting out of the collectors!! That can't be good for any near by wiring, lol.

Another open headers thread? j/k.

Seriously, if you continue to run open headers, you run the risk of burning valves. If you must drive it Monday, I would keep your toenail outta the carburetor, so to speak.

The risk of burning a valve is greater when you do not have headers at all since there is nothing to act as a heatsink.

CMan - I think the reason your CEL did not come on is that you just started it and it was idling. I am not sure though. When I did my H pipe, I also started it with open headers. I think it must be one of the steps to install an h pipe.
