Thread: anoter downpipe question (gaskets)

i ordered the offroad dp and just got it today. I also ordered the front and rear gaskets with the pipe. question- which gasket is the rear and which is the front? One of them has like a felt material and the other is a thin piece that looks like its made out of a pop can. If the job doesn't take too long and seems easy enough, i'll try gettin' it on tonight.
