CEL Issue
CEL and VSC came on after 300 miles.
Problem occurs at high RPM after 110 Miles per hour.
Lexus error codes from OBD:
PO420 P0430 Meaning
CATALYST EFFICIENCY BELOW THRESHOLD BANK1 AND BANK2
Talked with JUNTW but they don't accept any liability.
Went to a very good exhaust shop intrduced to me by LEXUS
They said that JUN cats are very poor quality and they use the extenders to rear O2 sensors on Y pipe to lie to ECU.
Had to change the cats with high flow HJS Germany 200CPI 150 HP each and rear O2 sensors bolted directly to Y pipe.
That added another 900$ in the budget.
They gave me a 90 days money back guarranty if CEL comes on again.
As it seems our car can't tolerate cats made in China.
If you go for a full exhaust from JUN think twice before you get the cats along.
