Will the diffuser scrape on steep inclines or driveways?

Rear diffusers sit lower than stock bumper panels. Before installation, verify ground clearance at your vehicle's approach angle and driveway slope. Measure from your current rear bumper contact point to confirm adequate space for the diffuser extension.

Do I need to modify my exhaust system for this to fit?

Yes. This diffuser requires exhaust modifications to mount properly and avoid contact with your exit pipes. Plan your exhaust routing before installation — whether that's relocating tips, adjusting pipe diameter, or repositioning hangers.

Is this functional downforce or purely cosmetic?

The GT racing profile is designed for visual authenticity to competition styling. Real downforce benefits depend on vehicle speed, aerodynamic balance of your full setup, and track conditions. Use it for the aggressive rear-end look it delivers — any aero gain is secondary.
