Will this diffuser clear my exhaust tips on stock height?

Exhaust clearance depends on your tip diameter and mounting position. Measure your current tip location and compare against the diffuser profile before committing to fitment. Most aftermarket exhaust systems sit lower than OEM, so verify your specific setup.

Does this cause scrape on driveways or steep inclines?

A seven-piece diffuser system adds profile to the rear bumper area. Ground clearance is determined by your suspension height and driveway angle. If you're running lowered suspension, test approach angles in your typical driving environment before final installation.

Is this functional downforce or cosmetic?

The TKO RBS diffuser is designed for wide body styling and visual impact. Real aero benefit depends on vehicle speed, suspension tuning, and how the entire rear end is configured—not the diffuser alone. Think of it as the aesthetic foundation of a wider, more planted rear stance.
