Stainless Works M15LDSFC Lead Pipe Kit Factory Connect for 15-25 Mustang GT

Vehicle Fitment

• 2015-2025 Ford Mustang GT (5.0L Coyote V8)

Fitment Notes

• Compatibility restricted to Stainless Works/Stainless Power headers only - this lead pipe kit is not designed to work with headers from other manufacturers
• This is the Factory Connect variant, meaning it's built to route into the stock factory exhaust or a necked-down aftermarket exhaust at the factory connection point. Two other connection variants exist for this same application: Performance Connect (M15LDSPC) and Aftermarket Connect (M15LDSLG) - confirm which downstream exhaust configuration you have before ordering, since picking the wrong variant means the pipe won't mate up correctly
• This is a mid-system component, not a standalone exhaust piece - it's intended to bridge Stainless Works' high-flow cats to whatever comes after it (factory or aftermarket exhaust), not to be installed on its own
• Built to order - expect approximately 4 weeks lead time rather than off-the-shelf shipping

Features

• Purpose-built to complete the Stainless Works/Stainless Power exhaust flow path: Long Tube Header → High-Flow Cats → Lead Pipe Kit → Factory or Aftermarket Exhaust

Product Description

When running a Stainless Works or Stainless Power long tube header system on a 5.0L Mustang GT, the lead pipe is the connecting piece that bridges the high-flow catalytic converters back to whatever comes next in the exhaust path - whether that's the stock factory exhaust or a necked-down aftermarket system. The M15LDSFC is the Factory Connect version of that lead pipe, built specifically to mate up to the factory connection point rather than a performance or aftermarket-style flange.

Built from 304 stainless steel and TIG welded in-house at Stainless Works' Ohio facility, this pipe is engineered to work exclusively within the Stainless Works/Stainless Power header ecosystem - it's not designed as a universal or cross-brand fitment piece. Getting the connection type right matters here: Factory Connect, Performance Connect, and Aftermarket Connect versions all exist for this same application, each built for a different downstream exhaust configuration.

This kit suits Mustang GT owners who already run (or are installing) Stainless Works/Stainless Power long tube headers and high-flow cats, and are keeping their factory exhaust or connecting to a necked-down aftermarket system rather than a full aftermarket connect setup. Since this is built to order, plan for roughly a 4-week lead time rather than expecting same-week shipping.
