Scoobmeister,
I have run a car on the rollers before and after fitting obx equal length headers. Have the print outs to prove. Car made 20bhp more and 3 lb-ft more with headers. It makes the car sound more throaty and have completely lost any sign of flat four sound.
IMO a good mod.

Agree with trout2 ; I have a recently imported STi with equal length on and it feels really odd. No 'Subaru'engine noise and a radically altered power band. It is chipped and it does go like hell just doesn't drive like I expected it to.

If I knew what I no now, the only mods that I would do for maximum performance and minimum cost is:
1) Decat Exhaust
2) K&N Flat Panel Filter
For more power you will need to remap the ECU
For track day use:
3) Up Rate Springs/shocks
4) Bump Steer
5) AP Racing front brake Kit
6) High Pressure pump & Swirl Pot
