Product Description

The Stainless Works M15LDSLG is an Aftermarket Connect lead pipe kit designed for 2015-2026 Ford Mustang GT builds running Stainless Works or Stainless Power long tube header systems. It serves as the critical link between the Stainless Works/Power high-flow catalytic converters and a third-party aftermarket catback exhaust, completing the full header-back exhaust path: Long Tube Headers → High-Flow Cats → This Lead Pipe Kit → Other Manufacturers' Aftermarket Exhaust. Both pipes feature 3" mandrel-bent tubing with full 3" ID inlets and outlets, ensuring zero restriction in the exhaust path, along with O2 sensor bungs on each side for proper sensor fitment.

Built from 304 stainless steel and fully TIG welded at Stainless Works' facility in Streetsboro, Ohio, these lead pipes are a replacement or upgrade component for builds pairing Stainless Works/Power headers with non-Stainless Works catback systems. Note that cutting may be required to achieve proper fitment with certain aftermarket exhausts, and these pipes are not compatible with factory stock headers. Backed by Stainless Works' Limited Lifetime Warranty on materials and craftsmanship, and made in the USA.
