i dont have headers but the system it's self makes great power. he only thing i notice between with and without mufflers is possibly slight low end torque loss.
however its only in theroy since i feel it's just the added volume plays a trick that i think it should be pulling harder when it's not. havent had it on the dyno to test one vs the other.
