Rear Diffusers for the 2016-18 Chevrolet Camaro (sixth generation, pre-facelift): finned rear diffusers, diffuser fin extensions and bumper-integrated diffusers in carbon fiber and ABS. The diffuser finishes the rear view and pairs with your exhaust tips and spoiler. Everything on this page is confirmed for Camaro fitment.
The 2016-18 cars carry the original sixth-generation front fascia and tail lights; the 2019 refresh changed both, so bumper-mounted parts are sold as 2016-18 or 2019-24. Rockers, decklid, doors and interior are shared with 2019-24, so skirts, spoilers, steering wheels and interior trim fit every Alpha-platform Camaro. SS and ZL1 front bumpers are different parts. This page covers LS / LT, SS, ZL1 and 1LE; each listing states the exact trims and model years it fits.
Materials run ABS plastic and carbon fiber. Carbon fiber parts are UV clear-coated; ABS and polypropylene parts ship primed or finished as listed.

Is the rear bumper trim-specific? Often yes — V6/LT, SS and ZL1 rear valances differ. Each listing states the exact bumper it fits.
Does it fit with aftermarket exhaust tips? Diffusers here are designed around factory tip positions and clear most quad-tip aftermarket systems.
