Frequently Asked Questions

Q: What does 'extreme corrosion chamber testing equivalent to 5 years' mean?

A: 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.

Q: Why use a Black Chrome process?

A: The chrome process helps bond the Black coating to the metal better than alternate coating processes, which helps with corrosion resistance and discoloration.

Q: Does this exhaust tip reduce exhaust tip temperatures?

A: Yes. The Black Chrome Exhaust Tip reduced maximum exhaust tip temperatures by up to 100°F at the hottest moments during GM testing and validation.

Q: Will an exhaust tip fit on my vehicle?

A: Yes, as long as you ensure the inlet size of your exhaust tip matches the diameter of your existing tailpipe and that the outlet size of your exhaust tip will fit through the bumper cut-outs on your vehicle.

Q: Can I install an exhaust tip on my own?

A: Yes, some exhaust tips can be clamped on or screwed on with a screwdriver.
