GM Engineers performed 25 cycles of 3-stage corrosion chamber testing to validate the Black Chrome Exhaust Tip. The test includes 8 hours of an ambient stage with a 1% complex salt spray, 8 hours of a humid stage and 8 hours of a dry-off stage to replicate extreme conditions and validate each tip for resistance to discoloration and corrosion. Additionally, the tips are subjected to a 2-hour thermal heat soak at 392°F for discoloration evaluation.
The chrome process helps bond the Black coating to the metal better than alternate coating processes, which helps with corrosion resistance and discoloration.
