Open Headers?

I'm getting closer to having my Kooks installed. I haven't decided if I'm going to do the exhaust myself, or take it to a nearby shop. If I take it to the shop (about 3 miles away), I'll drive it or have to have it towed. I've heard different opinions about running a car with open headers (throwing off the o2 sensors). Would this short of a distance be enough to cause any problems...other than upsetting the neighbors?

Don't worry about pissing off the neighbors for a one time drive to an exhaust shop. I had to make a run to the local napa to get new muffler gaskets with open manifolds, turned alot of heads but I didnt have any signed petitions waved at me when I got back And I live in a quiet neighborhood.

Sounds good then. I'm still considering doing it myself...if I can remember how to weld, lol. I was thinkign about putting dumps on it too but I figure I'm gonna be running a race muffler so I expect it to be loud enough.

While you've got access run a drain line away from the AC so that the condensation doesn't drip on the header.

No worries! No A/C here. I never used it so I pulled it. Opens up so much room in the engine bay to work, and the car runs so much cooler without the condenser there. I actually had the old exhaust off and old headers out in a little over an hour.

Are these headers long enough to not burn an exhaust valve up? If I recall correctly some of our more knowledgable guys didn't recommend running open headers as the possibility of burning an exhaust valve up was possible. It may have been because the car was untuned. I know when I installed my Kooks, that was the reason why I had the car towed to the exhaust shop.

The A/C was not what caused that problem...

But it's so much fun! lol

I ran my Cutlass with open headers for about a week. I think I was cool for about 10 minutes.....after that I couldn't stand to drive at any sustained speed for more than a mile and I finished up the exhaust as soon as I could.

But, it's a highly recommended experience to try once.

This was the reason I asked. I've heard of this before. Even if I did drive it there, it's like 3 miles away, and I'd take it easy driving there.

I'm not sure if I'm gonna have them do it now though. They want $200 to run the pipe, and that's not including the flanges or muffler or tips. Looks like I need to warm up my welding skills and make use of my friend's pipe bender.
