Differences between GenI and GenII: there are other differences (besides the exhaust) that stand out:
1. The engine
The majority of reference to “GenI and GenII” refers to engine changes, as there are several differences between the two engines, not the least of which is horsepower. GenI was rated at 400hp, later GenI (96) were rated at 415, and the GenII is rated at 450 (ACR & GT2 rated at 460 due to smooth tubes and filters).
2. The hood
The GenI cars have "smoothie" hoods with no NACA duct between the headlights and no vents above the wheel wells. The cars look different from the front with these changes.
3. Suspension
Changed to GenII suspension in 96. Both the GTS and RT have the same GenII components.
4. Exhaust
Went to rear exit exhaust in 1996
5. Other changes
Power windows, airbags, steering wheel, method of opening the doors, differential housing, CD player, speedometer, wheels, all changed from GenI to GenII
ABS added in 2001
Forged pistons deleted in 2000
Lumpy cam deleted in 2000
