[QUOTE="Todd Z, post: 603093, member: 58941"] The 2 front Pre cats help heat up the exhaust air for the back 2. the hotter a cat gets the better it works and the faster it gets warm the quicker it works.. The 2 fronts heat up the back 2, and only the front of the back 2 is monitored by an 02 sensor.. But removing the back 2 with out an XCal2 will set off a Check engine Light., Todd Z [/QUOTE]
