I had high flow cats & complete 2.5 stainless exhaust installed about 6 months ago.Everything was fine until about a week ago,I keep getting a
p0430 code,bank 2 cat below effiency threshold.I suspect it's a bad cat but
which side is bank 2????pass side???
thanks for the help
Rob

When you are looking on your motor from the front, you see
on the left side bank 1-4 and on the right side bank 5-8.
But the are only two manifolds, one on the left side (bank 1) and one
on the right side (bank 2)
