37 Pontiac 6 Touring tailpipe installation in Pontiac Flathead Owners Posted December 29, 2020 Thanks guys for chiming in. Actually I have the manual diagram and the Lubrication Chart which I've studied in-depth before starting this post. Neither told me what I was searching to find out. I was hoping a '37 owner with plenty of history would know. In my experience diagrams don't tend to be extremely accurate with the detail in line drawings since they're usually simplified to begin with. By examining both of these diagrams you can't tell where the 7" bend, at the end of one tailpipe section, is located. If that 7" bend is at the rear of the muffler it would be located directly under the cross-member of the chassis which is solid black and therefore the bend would be hidden. If it is at the bumper end it would not appear straight like the diagram indicates, but angled, which could result from the lack of detail, hence still undetermined. In summary I can't really trust these diagrams for their accuracy which is why I started asking for help on how current '37 tailpipes are installed. Maybe I should be asking, did original 1937 Pontiac 6 & 8s always have a 7" long bend on one end of their tailpipes or is this a modern reproduction addition?
