My exhaust fell off driving down a gravel road the other day so I made a quick fix and ran a straight pipe until I could fix it. I am thinking about doing a simple glass pack and pipe is there a problem with dumping exhaust under the cab of an el camino I have seen some like this. As soon as I said it my father was up in arms about the cab filling up with fumes and knocking me out when I was sitting in traffic. Just want to make sure it is safe to do. :dontknow:Thanks for the info.
