Ford F-350 Performance Exhaust - aFe Twisted Steel 1-7/8in 304 SS Headers (2020-2021) is a direct-fit shorty header system engineered for the 7.3L V8. It replaces restrictive factory manifolds with mandrel-bent stainless steel to improve flow and throttle response.

Built from 1-7/8" 304 stainless steel and designed with computer-aided precision, these aFe Twisted Steel headers are intended to fit in stock locations without cutting or modification. Heavy-duty laser-cut machined 304 SS flanges and 100% MIG-welded construction provide a durable, leak-resistant connection. The 4-to-1 mitered merge collectors reduce flow turbulence and increase exhaust velocity. On aFe’s in-house dyno this design produced gains of up to +18 HP and +25 lb-ft of torque; owners can expect improved midrange power and crisper throttle response when properly installed with the factory exhaust.
