Downpipes

[mnoll406]

Has anyone used stainless flex pipe like you see on semi's to fab a down pipe. JC whitney sell this at a reasonable price, and seems like a good solution instead of custom bending or fabbing.

It does not last. I've used it on skid-steer loaders on the farm and the diesel vibration tears it apart very quickly.

Yeah - it won't last and won't bend any significan't amount.  Like 10-15 degrees or something.  I cracked a couple on a normal gasser engine that was driven really hard as a replacement for the stock flex pipe when I upgraded the exhaust and downpipe.  I fixed it with better engine mounts and a ball-socket pipe connection.  Not that you needed to know that...
