Any one have any thoughts? Exactly as the title says long tube headers for a 5.3L this is going into an 87 SWB truck so maybe a block hugger would clear the frame? but I am just wanting some input, does this affect the 02 Sensors I men I know the wiring would have to be longer, but does the placement further down stream change anything with 02?
