Will the diffuser scrape on steep driveways or inclines?

The diffuser extends below the factory rear bumper line. Check your driveway's steepest approach angle and compare it to your vehicle's current breakover clearance. If you regularly experience scraping with the stock bumper, plan your entry angle or consider ramp adjustments before installation.

Does this diffuser require exhaust modifications?

Yes — exhaust modifications are required for proper fitment. Your exhaust exit points and routing must clear the diffuser panels. Work with your installer or exhaust shop to confirm clearance before committing to the purchase.

Is this functional downforce or purely cosmetic?

This is a GT racing-style diffuser designed for visual impact. While the profile mimics racing geometry, actual aerodynamic benefit depends on vehicle speed and overall setup. Treat it as styling first; any aero benefit is secondary and speed-dependent.
