Why this part
Cheaper headers cut corners on bend radius, which chokes mid-range torque where you actually ride. The Attitude Inc Razors use big-radius geometry to keep exhaust gas moving efficiently across the full power curve. Precision heat shields and mounting hardware are included, so you're not sourcing extra parts before the bike goes back together.
