Installation & Maintenance Tips

• Installation:
  Ensure engine is cool before installation. Fitment should be done using OEM mounting brackets or custom-welded flanges. Replace gaskets if present to avoid leakage. Ensure correct pipe orientation for optimal gas direction.

• Maintenance:
  Periodically inspect for carbon buildup, weld cracks, or rust spots. Clean external surfaces with a non-corrosive degreaser and inspect internal baffles using an inspection camera during scheduled servicing.
