Does this fit with my current exhaust, or do I need to modify it?

This bumper is cut for M4 exhaust. If you're running stock exhaust or an aftermarket setup with different exit holes, you'll need to modify the cutouts or source an M4 exhaust. Check your exhaust outlet size and position against the bumper opening before final install.

What finish should I apply to the surface?

Sand and prep the surface following your chosen paint system's requirements, then apply primer, color, and clear coat to match your vehicle.

Are there sensor holes cut into this bumper?

Reference your vehicle's OEM bumper to identify parking sensor locations and any other integrated electronics. You'll need to drill or cut corresponding holes in this cover to maintain functionality—plan for that modification before final installation.
