Also fun fact on the stock EPA Catalytic exhaust it gets to around 420 degrees Fahrenheit. This is the hottest part of the engine. So yes 500 degree Duplicolor paint will work fine.

Also because the EPA exhaust has WAY too much back pressure it gets much hotter that it should. Thatís why Iím making a custom exhaust with a "tuned to the engine rpm" expansion chamber (also custom).

(Picture of exhaust coming soon)
Would you say that high back pressure harms the engine at all?
