here is my question.
how much hp we are looking from OBX?
what else is needed to make the OBX header work?
why are they so cheap?
* SUS-T304 stainless steel * Individual pipe for each exhaust port * Mandrel bend for smoother airflow to decrease resistance * Increase engine output and efficiency * Limited time warranty from manufacturer defects
Spec:
* Primaries: 1 3/4" * Lead Pipe: 2.5" * Four o2 ports * No EGR
