Stainless Works M15CBX-LMF Retro Series 3" Cat-Back Exhaust System with X-Pipe Factory Connect

The Stainless Works M15CBX-LMF is a complete 3" dual cat-back exhaust system built for the 5.0L Coyote V8. Featuring a factory-connect X-pipe design, this Retro Series system delivers a deep, aggressive, drone-free exhaust tone while improving overall exhaust flow compared to the stock system. Engineered and TIG-welded at Stainless Works' facility in Streetsboro, Ohio, this system is backed by a limited lifetime warranty on materials and craftsmanship.

Retro LMF Chambered Mufflers: This system is equipped with retro-style chambered LMF mufflers featuring large 3" cores, producing a significantly louder, more dominant exhaust note than the standard 2.5" core variants. The X-pipe crossover design improves exhaust flow efficiency and enhances upper-RPM power delivery.

Key Features:

• 304 stainless steel construction for superior corrosion resistance and long-term durability
• Full 3" mandrel-bent tubing for smooth, unrestricted exhaust flow
• Retro chambered LMF mufflers with 3" cores for an aggressive, high-volume exhaust note
• X-pipe crossover for improved flow and upper-RPM performance gains

• Factory connect design — mates directly to OEM factory exhaust manifolds, no modifications required
• Fully TIG-welded construction for precision fit and lasting strength
• Includes all necessary hangers and clamps for installation
• California legal (CARB compliant)
• Limited lifetime warranty on materials and craftsmanship

Installation is a straightforward bolt-on process. This system connects directly to the stock factory manifolds and includes all required hardware, making it a direct-fit replacement upgrade with no cutting or welding needed. Compatible with automatic and manual transmissions.
