Pypes Full Length Headers & X-Pipe, 2011-2014, GT, With Cats. Our Pypes team though out of the box when we set out to design a header system to take advantage of the awesome power that Ford engineered into these cars. What we came up with is "Tube Step Technology" to increase exhaust gas scavenging that netted 45hp and 19tq to the wheels! Constructed of mandrel bent 304 stainless steel the primary tubes start off at 1 3/4 and then step to 1 7/8 and finish with a 3" ball socket collector for excellent sealing. The kit includes with a full 3" 409 stainless steel x-pipe with twin metallic substrate cats and all the hardware to install the kit.
