If your engine’s lagging, misfiring simply not up to par, you may have a toasted catalytic converter. When the engine block, ignition coils, vacuum pump, seals and such fail, unburned fuel and other contaminants get can into the converter and wreak havoc – like melt your core and other such ugliness. Evan Fischer proudly offers you quality stainless steel catalytic converters that are legal in 47 states, meet and beat EPA/OBD-II requirements and are actually test fit on real driving vehicles. And they’re relatively inexpensive compared to a big, shiny number from the big brands.
