Can anyone compile a list of differences between the early 997 and mid 997 generation cup cars?

I am looking at both 06 and 09 cars at present.

early 05-07
late 08-09

early: single flap intake manifold
Late: Dual flap intake (more power)

early: 996 style headers and exhaust
late: cats in headers, street style gt3 muffler or open supercup style

early: rear bumper for early exhaust
late: rear bumper looks more like the street gt3

The early transmissions if not updated have the narrow gears, non floating dog teeth, narrow shift forks and the cast diff housing. A lot of early cars have had updates done but if not, it can be very pricey to fully update an early transmission and diff. The early cars also have a slightly shorter 5th and 6th gear ratio.

It is hard to update the early intake manifold because a lot of the water console parts are different. The late intake and exhaust gives the car 15 or so more hp. The supercup exhaust another 5-6.

There may be more differences but that is a quick list of what I remember.

Thank you for that. So the standard 08/09 muffler is the same as the street car or similar?

Mufflers are different. Street cars have two inputs per side. Cup muffler is single per side and has less baffling inside. Integrated tips as well.
