Long Tube Headers 1-7/8" Primary Tubes Stainless Steel

These headers feature 1-7/8" primary tubes, 3" collectors, and a .375" thick flange for a durable and tight seal. They are designed as a direct replacement for restrictive factory exhaust and catalytic converter systems, aiming to unlock your car's hidden power potential. Experience a significant power boost with up to 49 additional horsepower and 32 ft-lbs of torque. The design incorporates computer-optimized collectors for maximum airflow and low-profile, four-bolt collectors. For a reliable, long-term installation, "OEM-style" triple-layer stainless steel gaskets are included, along with all necessary hardware. The manufacturer notes that all 2011-13 GT500 Mustangs came standard with a 2-3/4" exhaust, implying these 3" collectors are an upgrade over stock. These headers are specifically designed for the 2013 Ford Mustang Shelby GT500 with the 4.6L Ford Modular V8 engine. While designed as a direct fit, it's worth noting that some older Dynatech long tube header part numbers might physically resemble earlier model years, but the 722-84310 is confirmed for the specified application. The installation time is estimated between 6-8 hours.
