The MagnaFlow 15714 is a stainless steel cat-back exhaust for the 5.4L Ford F-150 Lightning, replacing the stock exhaust components from near the catalytic converter on back. Extensive 3D scanning during development has resulted in a direct-fit design, and the manufacturer describes dyno-proven performance from CNC-produced parts. Against a budget pipe, the case for this kit is corrosion-resistant construction and a warranty that runs for the life of the part. Stainless Steel Systems carry a Limited Lifetime Warranty against Manufacturing Defects. One owner on a user forum called MagnaFlow cat-backs for Lightnings can't go wrong.
Verify fitment before ordering. The manufacturer's product page names the 1999-2003 Lightning, and information for 2004 SVT-badged trucks varies, so confirm with the manufacturer first. Owners on user forums have warned that tip angle can crowd the nerf bars on Lightnings, which happened with a slightly used borla kit, so measure your tip clearance. Shoppers searching for a 5.4L supercharged SVT Lightning side-exit cat-back, a 15714 stainless cat-back, or a bolt-on 1999-2003 F-150 Lightning exhaust will find this kit covers the core stainless, side-exit layout they want.
The manufacturer's product page lists 1999-2003 Lightning models. Fitment details for 2004 trucks vary, so confirm with the manufacturer before ordering for a 2004.
No. The manufacturer's specifications state that neither a mounting bracket nor a gasket or seal is included with the 15714 kit.
The manufacturer's warranty policy provides a limited lifetime warranty against manufacturing defects on stainless steel systems. It does not apply to commercial or racing vehicles or to products that were improperly installed.
The manufacturer describes this as a bolt-on installation and says it may require basic automotive knowledge, with professional installation always recommended. The kit includes the hardware needed for a DIY job. Support the truck securely on jack stands before working underneath. Per MagnaFlow's installation sheets for other truck systems, spray penetrating lubricant on the old fasteners and hangers and let it soak before removal. Because no mounting bracket or gasket ships in the box, check how the stock system was attached before you start, and note the clamp-on inlet when lining up the new pipe.
