   • Dampens vibration and protects the exhaust system from stress.

3. Durability:

   • Built to endure the high pressures and temperatures typical of the Nissan UG engine's exhaust system.
   • Resistant to wear, corrosion, and the corrosive effects of exhaust gases.

Material:

• High-Quality Metal Construction:
  • Usually made from stainless steel, heat-resistant alloys, or similar materials.
• Graphite or Ceramic Coating:
