Do I need to remove the factory bumper before installation?

Yes. You'll remove the OEM bumper and transfer hardware to the new FRP cover using the factory mounting points. The one-piece design mounts the same way the original does.

Can I paint this before bolting it on?

Absolutely. Sand and prep the primer surface, then apply your chosen paint and clear coat while the bumper is off the vehicle. This gives cleaner coverage and easier handling than painting on-car.

Will this fit with an aftermarket exhaust or diffuser?

Check your exhaust exit and any diffuser height before ordering. The Type JS profile has specific cutout placement — verify that your exhaust pipes or diffuser components clear the opening. Measure twice if running low-mount or side-exit systems.
