[Healeys] Stainless exhaust again

Here is what happens to a mild steel resonator after a few years of
sitting with water inside or hot/cold pipe driving conditions. Keep
spares, or go for stainless, and loose the sound effect. I blame this
one on covid. Hank

 When you park the car after a long drive, water will collect in a
mild steel exhaust system and relatively quickly the welds in the
internal baffles on the silencer will corrode and break away. So
whether you drive the car or not the silencers corrode internally.
having SS silencers is a good idea. pipes can be mild steel and they
will last forever.

SUBJECT: Re: [Healeys] Stainless exhaust again       I make my own
front pipes for 100's because the cheapo repos are so terrible. I use
mild steel for the pipes, which I actually had mandrel bent in New
Zealand because no one in Canada seemed to be able to bend them to the
correct radius but, and pretty soon I'll get to the point of this
email, I weld the stainless flex to the mild steel with my TIG welder.
 I use mild steel for the pipes because I have yet to see a front pipe
that has rusted through unless the car is driven extensively on salted
roads. I'm sure anyone who does TIG welding could do the welding for
you in mild steel but if you are prepared to pay handsomely FAB
Stainless Welding could do them in stainless 905 669 7400 ask for
Frank. BTW the stainless steel flex seems to leak slightly when first
installed but that stops after a little use, the gaps probably fill
with carbon.

 The new downpipes arrive today, and I did a test on them before going
to the trouble of putting them on the car.
 Well…Bell exhaust systems need new welders, because the two pipes
both leak at the welds AND through the flex pipe!
 I’m trying to find someone local to fix them, but most muffler
shops say they can't weld stainless.
 If anyone knows someone in the Toronto area who can do this work,
please let me know.
