Can I start car with open headers?
I have had the car on jack stands for about a week and want to start it to keep battery from dying as happens on C6 if you dont start regularly. I am waiting on exhaust stuff so need to start the car with open factory headers/cats. Will this jack anything up or will all be alright?

I have done this on Mustangs, BMW's and Hondas with no prob. I have not done it on the vette though. Im gonna have to in the near future though. Im thinking the worst thing that could happen is engine check in some cases.

I started my '05 coupe last Thursday for the first time in about 3 weeks and had no problem.

When we changed the clutch on my ZR-1, there was no way the exhaust was going on before we got to hear that beast with open exhaust....and it was definitely worth it.
for video of you starting your Vette with open headers.

Battery tender
I started mine with Heads & Cam and it was extremely loud. I drove it a few miles for two days with no problems, prior to installing the mufflers. l loved it at first, but after a while it can make you go deaf. If you don't try it, you might regret it. You should still use a battery tender suggested by Mez. I use one all year to keep the battery fully charge. Let us know if you try it, and how it sounds.
