Interesting take. I've had test pipes for about a year and they are difficult to distinguish from the stock exhaust (if your unaware that it should have secondary cats). The car was state inspected with the test pipes and no one batted an eye. Stainless is a pretty common exhaust material on high end cars, flat black paint? Not so much. I think the paint is the more conspicuous of the two.

painting the pipe will increase the emissivity of the pipe which will increase the temperature in the engine compartment.

Got my Test pipes in and just installed them last night. Combined with the Top Speed Exhaust im real happy the way it sounds. Have to get some exhaust leaks figured out since the clamps didnt exactly fit will but all in all very happy

I was going to wrap mine in heat tape but one of my co workers cautioned against that since they put Mag Chloride on our county roads out here and I have to drive just under a mile on gravel to get to my house.

The whole muffler has hi temp paint to hide the ugly thing when viewing from the rear. Been doing this for years on my cars were the muffler shows. Not too worried.
