The Texas Speed 1-7/8" Long Tube Headers with Catted Connection Pipes pairs the Texas Speed S550 long tube headers with catted connection pipes for the 2015 to 2023 Ford Mustang GT 5.0L. The headers are 304 stainless steel with 2.0 mm wall tubing, mandrel bent on CNC benders, and they finish in 3" merge-style collectors with a welded O2 bung and a velocity spike for improved power and torque.
The connection pipes carry catalytic converters and are supplied with exhaust clamps, TSP MLS exhaust gaskets and front O2 sensor extension harnesses, so the kit covers the hardware normally needed for a header install. The O2 extension length is chosen when ordering based on model year, and Texas Speed offers a header stud kit as an optional add-on.
