I knew I could wake somebody up
We needed to get something going on this site. You guys are all too busy DRIVING your cars in that southern climate instead of giving all the good input into this forum. All we can do in Wyoming this time of year is think about driving or tinker in the garage. (well heated of course).
I did, however, just put a long hose clamp around the two flanges on my headers and sidepipes to act as an external seal. Works great! Even if it does leak a little, who's going to hear it?
If I'd bought a real one, I'd park it. Since I built a real one, I can drive it!
