Performance part comparison

Steeda ProFlow Intake vs Ford Performance Dark Horse Cat-Back

Two common first modifications for an S650 Dark Horse target completely different parts of the driving experience.

CURRENT VERDICT

Steeda S650 Mustang GT/Dark Horse ProFlow Cold Air Intake

The intake is the better first performance-oriented bolt-on when airflow and future tuning are the goal. The Ford cat-back is the better choice when sound and factory-backed exhaust integration matter more than power-per-dollar.
