Just a Quick Tip.

If you ever have your car in the air or your underneath, take a bit of copper anti-seize and put it on every nut and bolt you can find.
Cuz down the road when you go to swap exhaust's or change struts or sway-bars, it'll save your ass.
I did mine when I was painting my calipers, I put it on the bleeders for the calipers, the all the exhaust bolts and nuts, the sway-bar end link nuts and studs, I also put it on the exhaust manifold heat shield bolts and all the nuts.

This stuff doesn't wash off and will last for years. I checked mine the other day when I was changing my oil, and it was all still there even after driving through like 3 rain storms and some snow. :bt:
