New 20b NA Headers by Defined Autoworks

[diabolical1]

a 28 hp increase over stock? Gordon, my hat goes off to you and your fabricator-guy. that is awesome. how did the torque curves compare?

i can only imagine when the motor is fully broken in and the seals are bedded. do you plan to take the Defined header back off just to compare bedded versus non-bedded, or will you simply compare the differences with the Defined header?

not to speak out of turn, but i believe he's running a single set of Injector Dynamics 1000s (i.e. no secondaries). i have no idea what apex seals though.
