The thing they removed–the heat shield–is a thin metal covering that surrounds the catalytic converter, which gets very hot when the engine is running. But we think it’s our moral obligation to tell you that removing any part of the heat shield is potentially dangerous.

What does a heat shield do?
Heat shields protect structures from extreme temperatures and thermal gradients by two primary mechanisms. Thermal insulation and radiative cooling, which respectively isolate the underlying structure from high external surface temperatures, while emitting heat outwards through thermal radiation.
How much does it cost to remove a heat shield?
The parts, which are just pieces of sheet metal and a few bolts, should cost about $160 from a Honda parts department. And the job takes about an hour of labor. That means you should pay somewhere between $250 and $300 to have this done.

The short answer is that it’s not as necessary as the main sheet guards, but additional shields can keep the driver and passengers more comfortable and save you money on replacement lines and inefficient use of fuel.
