Product Description

The Stainless Works M15LDSPC is a Performance Connect lead pipe kit designed to complete the exhaust path between Stainless Works or Stainless Power long tube headers and a Stainless Works catback system on 2015-2026 Mustang GT, Dark Horse, Mach 1, and Bullitt models. With 3" mandrel-bent tubing, 3" ID inlets, and 3" OD outlets, these pipes maintain a full, unobstructed exhaust path - unlike the Factory Connect variant which necks down at the outlet. No cutting is required, and both pipes include integrated O2 sensor bungs for proper sensor fitment. The install sequence is straightforward: Long Tube Headers → High-Flow Cats → This Lead Pipe Kit → Stainless Works Catback.

These lead pipes are compatible only with Stainless Works or Stainless Power long tube header systems and are not compatible with factory manifolds. Built from 304 stainless steel and fully TIG welded at Stainless Works' Streetsboro, Ohio facility, the kit ships with four 3" clamps for a clean, leak-free installation. Backed by Stainless Works' Limited Lifetime Warranty on materials and craftsmanship, and made in the USA.
