<DIV>I'll second that: I have DW exhaust headers with no flex pipe in the
system and exhaust wrap that has been on for 23 years with no problems.

<DIV>An exciting subject indeed!</DIV></DIV>
<DIV><BR></DIV>
<DIV>I am about to fit an unused mild steel down pipe that I have had on the
shelf for maybe ten years. No sign of rust but I am away from home right now
so can not test it for flex. I might zap it with WD40 before fitting - can’t
hurt. </DIV>
<DIV><BR></DIV>
<DIV>The question is - when brand new do the mild steel down pipes ever show
any sign of flex?</DIV>

<P class=MsoNormal>As a follow up to my post on 10/18 on this exciting
subject, I decided to do an experiment with a couple downpipes I had in
the parts bin. Both pipes are new old stock and have never been on a
car. One is stainless and the other mild steel. Both have been
laying on a shelf in the garage for at least 9 years. </P>
<P class=MsoNormal>The test was to measure how much deflection was noted
in the flex portion of the downpipe when the tip (where it enters the
muffler) is loaded with a weight. The upper portion of the pipe was firmly
held by the bench vice. </P>
<P class=MsoNormal>Should have started with something less then 10 pounds
but the stainless moved considerably under that weight. The mild
steel did not budge.</P>
<P class=MsoNormal>At 47 pounds I heard a creaky noise but no movement on
the mild steel. I then applied an unspecified force with my hand to the 47
pounds and no movement. </P>
<P class=MsoNormal>My conclusion is that the mild steel flex pipe, once it
takes a set, ie, Gets Rusty, does not flex. It is the weak link that will
fail but it might as well be a piece of regular pipe.</P>
