What engines are compatible with these LS swap headers?
▾
The headers are engineered to bolt directly to GM small-block V8s ranging from 4.8 L up to 6.2 L. That covers the 4.8L, 5.3L, 5.7L, 6.0L and 6.2L LS-family engines commonly swapped into Fox Body and 1994-2004 Mustangs. Verify your engine’s block and bell-housing pattern before ordering to ensure a perfect fit.
Does the package include everything needed for installation?
▾
Yes, each set arrives with the header tubes, a full set of stainless-steel gaskets, and the necessary mounting hardware shown in the product photo. However, the package does not include a detailed installation manual, so you’ll need to reference a fit-guide or seek professional help for proper torque specifications.
How much horsepower gain can I expect?
▾
While exact figures depend on your engine’s condition, camshaft, and tuning, most owners report a 5-10 % increase in peak power after swapping to these LS headers. The improved exhaust scavenging also enhances low-end torque, making the car feel more responsive in everyday driving.
Is professional installation required?
▾
The headers are designed for a direct bolt-on fit, but achieving optimal performance and ensuring no leaks typically demands proper torqueing, gasket seating, and occasional welding of the exhaust pipe. If you lack experience with exhaust work, having a qualified mechanic perform the install is strongly advised.
Can I use these headers on a Mustang that originally came with a Ford V8?
▾
The LS swap headers are built for GM V8 block dimensions, so they will not bolt directly to a stock Ford 302 or 351 engine. To use them, you must first install an LS-style GM engine into the Mustang.
