This product is a consumable. It is recommended to buy two or three extra as backup.

Available Sizes

Choose the correct size based on your vehicle’s engine displacement and exhaust tailpipe inner diameter:

• S – For 1.0L to 1.6L engines
• M – For 1.6L to 2.0L engines
• L – For 2.0L to 2.4L engines
• XL – For 2.4L and above

How to Choose the Right Size

1. Measure the inner diameter of your exhaust tailpipe.
2. Compare your measurement with the product dimensions.
3. Choose the size that fits your tailpipe securely—when in doubt, select a slightly larger size for a stronger sound effect.
4. Important: If the whistle diameter plus 1 cm is equal to or larger than your tailpipe’s inner diameter, the product cannot be installed.

Key Features

• Realistic Turbo Sound Effect
  Creates a simulated turbo whistle when your exhaust airflow increases.
• Durable Aluminum Alloy Construction
  Built to withstand high temperatures and daily driving conditions.
• Universal Fit with Multiple Sizes
  Available in four sizes to match different engine displacements and exhaust diameters.
• Easy Installation
  No welding or complex tools required—mounts directly onto your exhaust tailpipe.
• Fun, Affordable, and Reversible
  Perfect for car enthusiasts who want a playful turbo sound without altering their vehicle permanently.

Important Notes

• Sound volume depends on your vehicle’s exhaust pressure and engine output.
• Different size whistles produce different sound levels—the larger the size, the louder the sound.
• Some vehicles with low exhaust pressure or modified mufflers may produce weak or no sound. This is not a product defect.
• Sound preference is subjective; the whistle creates a simulated turbo sound, not an actual turbo system.
