24in Extension 4in Dia

The Schoenfeld 24in Extension 4in Dia straight exhaust pipe extension is a purpose-built component for custom exhaust system fabrication and modification. Designed for builders and mechanics working on street rods, race vehicles, and engine swaps, this extension allows precise routing and positioning of exhaust discharge points to clear engine bays, suspension components, or body modifications. Whether you're relocating exhaust exits for aesthetic reasons or functional clearance, this steel extension provides a reliable, bolt-together solution without the cost of full custom mandrel bending.

Constructed from heavy-duty steel in natural finish, the 24in Extension 4in Dia features a straight design with one end expanded to accommodate standard 4-inch diameter piping connections. The 24-inch length—equivalent to 2 feet—provides sufficient material for mid-body or rear-axle routing without excessive weight penalty. Weighing 5.26 lbs, this extension maintains structural integrity while keeping overall exhaust system mass minimal, critical for performance-oriented applications. The expanded end design simplifies welding or clamping procedures, reducing installation time and ensuring repeatable, leak-free connections in high-temperature exhaust environments.

Fabricators, hot rod shops, and serious DIY mechanics benefit most from this Schoenfeld component when designing custom exhaust systems for non-standard engine placements or when original exhaust routing proves incompatible with frame modifications. The 4-inch diameter accommodates large-displacement engines and turbo applications where flow capacity is non-negotiable. Installation involves standard TIG or MIG welding and basic hand tools; ensure proper support and heat shielding to protect surrounding components. This extension pairs seamlessly with Schoenfeld's full line of mandrel bends and collectors for complete, professional-grade exhaust system assembly.
