What all can you remove from the engine bay like vaccum lines. egr, smog, etc ? Whatever isnt a necessity and if you removed all the smog stuff, but yet ran catalytic converters hi flow,for visual inspection, would it be legal.
Depending on what state your in, the EGR and Smug stuff is required for the visual. They almost failed me because they couldnt find my vapor canister and they thought i moved my SPOUT. All smog equipment is required for visual depending on where you go.
Well here they are not very strict all they require is 2 catalytic converters and then mufflers,they dont really look under the hood just under the car.
