Post-Installation Notes

Cold Weather Start-up Sound

Deeper/louder exhaust sound during cold weather start-ups is temporary and will normalize with engine temperature.

Initial Start-up Smoke

Trace smoke after initial start-up is normal, caused by burning manufacturing oil residue; do not be alarmed.
