Common Applications and Problem Solving

  • Reduction of excessive exhaust noise
  • Improvement of exhaust flow efficiency
  • Prevention of rust and corrosion in exhaust components
  • Restoration of proper exhaust system fitment and alignment

Installation Notes and Tips

Ensure compatibility with Mazda 5 exhaust systems before installation. The 2 bolt welded flange inlet requires proper gasket and bolt torque to prevent leaks. Due to the offset inlet and outlet configuration, verify alignment with existing exhaust piping. Stainless steel construction allows for welding if necessary, but use appropriate techniques to avoid damage. Measure overall length and body dimensions to confirm fitment within the vehicle’s undercarriage.
