i may be finally getting new exhaust

my bumper turns black in about two months from soot

a friend/neighbor told me this could be because the rich/lean off and im guessing this is because of faulty o2 sensors?

i do not have a check engine light on.

how do i put true dual exhaust on my truck with all the exhaust sensors going on one side because of the Y/cat/one in two out

setup that ive got. ive read that o2 sensors can affect your air/fuel ratio, and your timing

i want the best exhaust possible but i dont want to change anything drastic

can anyone tell me anything about the exhaust emissions systems on my truck

its a 96 k1500

what kind of setups does everyone go with just the factory y pipe then a cat then a muffler then two tailpipes?

i want two headers, two downpipes, two mufflers and two tips

how do i go about getting rid of catalytic converters and sensors without throwing off my engine
