well after getting restricted Performance light
And the following codes
P1647 02 sensor pre cat
P0302 MISFIRE CYLINDER 2
P0306 MISFIRE CYLINDER 6
​​And found all plugs on bank 2 black and stooy
after replacing all four 02 sensors at over 3k
Still had restricted Performance
So I bit the bullet and decided to remove downpipes
