## Discrepancy

EXHAUST COLLECTOR TUBES WERE CRACKED AND NEARLY UNDETECTABLE WITHOUT REMOVAL OF EXHAUST AND INSPECTION WITH A BRIGHT LIGHT SOURCE.  IT APPEARS THE CRACKS WENT UNDETECTED THROUGH MULTIPLE PREVIOUS INSPECTIONS FROM A REPUTABLE SHOP.  THE EXHAUST IS AN AFTERMARKET TUNED EXHAUST FROM PLANEPOWER.
