SLP's Long-Tube Header Package for the 2011-2014 5.0L Mustang GT features 4-into-1 CNC bent 1-3/4" stainless steel primary tubes flowing into two 3" merge collectors with an integrated spike for increased power, better scavenging, and improved sound. Headers are ceramic coated inside and out to keep heat in, exhaust velocity up, and under-hood temperatures down. Also included in the package are a pair of 3" 200 cell per inch high-flow catalytic converters, which flow into a full 3" PowerFlo-X® crossover pipe assembly and down-pipes which bolt to your factory or SLP axle-back exhaust systems. They are compatible with the stock emission-control equipment and use OEM-style flanges for a perfect fit and proper bolt retention. All necessary hardware and installation instructions are included and backed by SLP's Limited Lifetime Warranty.
