I've searched this on a couple of forums and can't seem to find an answer. People have speculated that this is not a problem as the Scud headers are a different design than the F430 but I have not seen a definitive answer.
Scud/16M header has no precats, that is the main difference. The headers are an update compared to the standard car, however the same stresses that cause the headers to fail with standard cars can also occur with Scud/16M but there are NO precats to fail and get pulled back into the engine and hence catastrophic engine detonation doesn't occur.
Even so, with a Scud it is worth looking at the Capristo sprung mount - or even going the complete route with Capristo exhaust!
'SCUD' Verb. To move fast as if driven by the wind.
One of my friends changed his stock headers already 3 times on his 16M...blown headers on the 16M, despite there are no pre-cats, represent still a potential engine failure risk as small broken steel parts can be sucked back in. Ferrari headers, whatever the model is, is really a weakness and something that need to be carefuly checked.
one could always make up some cast iron headers like Detroit city car manufacturers have done for years...they will last a long time :=)
header wear ( failure ) comes with the territory, it's part of the wear... the use of thin wall tubes is the only way to get tubes bent and drawn to correct shapes and length for maximum effect from exhaust tuning... each bend weakens that particular area making it more suscetible to burn through... welds build up joints for unequal response to heat for more issues... there is a simple choice between increasing performance and weight saving or settling for less performance with more weight to favor longivity
