Where in the regs is this so-called "attached" requirement? - GA
"Logic" is not enforceable regulation. Your assumptions and expectations are not enforceable regulation. The words used in the regulations are the basis for the letter and enforcement of the regulations.I would argue that it's simple logic.
Show me where it says you CAN add this type of thing...
Incorrect. While it may not be part of the exhaust pipe, it is most decisively part of the exhaust system, for without that exhaust pipe there would be no need for the exhaust shield.Exhaust heat shields attached to the car are not part of the exhaust system.

The rule states the system - not the exhaust piping as you are incorrectly assuming - is free. Thus it is.

See? You figured out your own response in one post, two paragraphs. +1 Internets for The Bettencourt.I disagree completely. By your logic the exhaust valves are also part of the exhaust system. Those must be free also.
Intorturtation.
the question was addition of heat shield material. I presumed based on common practice that this would be foil, aluminized insulation pads, etc... in the area of the driver.
generally, this is NOT a protested item. it's a stupid and nit picky protest used for 1 of 2 reasons - because you hate someone and are petty, or because someone is performing a prohibited function.
I disagree with Greg's reading, but I don't think it matters because, as above, it's just petty to call someone on insulation used appropriately and for driver comfort or engine survivability (reflective shield on the oil pan, etc...).
"Any exhaust header and exhaust system may be used" (GCR 9.1.3.D.1.g, p404 Dec 2012 GCR).
Heat shields are part of the exhaust "system".
