What to know before buying

Listing details to confirm

The listing is inconsistent about the finish, calling it gloss black and carbon-fiber while another description specifies painted Carbon Flash Metallic and elsewhere says unpainted matte black. Package descriptions also differ between a diffuser with housing and a 3-piece diffuser plus hardware. The 2020–2026 title differs from fitment wording of 2020-present, and installation claims conflict between direct replacement and drilling required. Confirm finish, exact fitment, package contents and installation needs for the selected listing.

Frequently asked questions

Which Corvette trims does the listing say this fits?

It names E-Ray, Z51 and Stingray models and explicitly says it does not fit C8 Z06 models. Confirm the exact year and trim because the title and fitment wording use different year ranges.

What is the diffuser made from?

The specifications list Acrylonitrile Butadiene Styrene (ABS).

Is the finish definitely gloss black?

No. The title and color field say gloss black, but other description text says Carbon Flash Metallic and unpainted matte black. Confirm the finish for the exact listing.

Does installation require drilling?

The listing conflicts: one feature describes a direct-replacement diffuser, while another description says drilling is required and recommends professional installation. Verify installation requirements before ordering.
