Hello,
I recently had my car flight judged at the Heartland Chapter meet back in September. The NOS exhaust tips that I purchased from GM back in 1981 that I installed when I originally restored and are currently on the car were judged as not original and received a points deduction. The reason why they were judged this was because the judge's magnet did not stick to the exhaust tip when applied. Again, these exhaust tips were purchased over the counter from my local GM dealer back in 1981 and carry the correct GM part number and have the correct seam that runs the length of the exhaust tip. After 23 years of service there is no sign of rust anywhere on these tips.
When you think of stainless steel you assume it is usually a 304 or 316 grade, not the magnetic 409 grade. What did GM use from 63 to 67?
Where the exhaust tips judged correcly??? In my opinion they were not. I know that stainless steel exhaust pipes, clamps, heat shields, etc. are a no no in flight judging, but are the exhaust tips supposed to be the opposite, as in a magnet should stick to them when applied?
Just trying to get some clarrification for my own knowledge as a 63/64 judge.
