where did catalytic converters go after they were placed a third of the way back from the engine?
close to the engine
as an alternative, catalytic converters were moved to a third of the way back from the engine, and were then placed underneath the vehicle.

section::::types.:two-way.









































a 2-way (or "oxidation", sometimes called an "oxi-cat") catalytic converter has two simultaneous tasks:









































bullet::::1. oxidation of carbon monoxide to carbon dioxide: 2 co + o → 2 co









































bullet::::2. oxidation of hydrocarbons (unburnt and partially burned fuel) to carbon dioxide and water: ch + [(3x+1)/2] o → x co + (x+1) ho (a combustion reaction)
catalytic converter
free-flowing exhaust systems may maximize peak horsepower by reducing or eliminating back pressure; this is typically accomplished by making the path as straight as possible, using a consistent diameter throughout the system and eliminating obstacles such as catalytic converters and pre-catalytic converters or by replacing the muffler with a less restrictive (and usually louder) one. despite the potential for increased performance by eliminating catalytic converters and other emissions control hardware, doing so will often render the vehicle illegal for street use in many jurisdictions. other aftermarket modifications that bypass the catalytic converters and/or mufflers, such as electric or cable activated exhaust cutouts—which open and reroute the exhaust flow to bypass restrictions in the system—can similarly increase performance, though would likely be illegal in areas where tampering with emissions devices is prohibited, particularly when placed in front of the catalytic converters.
