2001
2001 was the lowest production year for the Camaro with 29,009 units. This was partially due to production ending earlier than usual to begin work on the 35th Anniversary cars. The Z28 and SS models received the intake manifold from the LS6, the engine used in the fifth generation Corvette Z06 from 2001-2004. This change also resulted in a revised camshaft profile and removal of the EGR system. GM also introduced a new slave cylinder for the clutch assembly that was superior to the design of previous years, as well as an LS6 clutch in manual models. Accordingly, stated power ratings were increased to 310 hp (231 kW) for the Z28 and 325 hp (242 kW) for the SS which also added a power steering cooler. SLP reintroduced the RS model this year, which included rally stripes and stock cold air intake system and Z28 take-off exhaust (from their SS conversions).
