30in Extension 4in Diame

The Schoenfeld 30in Extension 4in Diameter provides a reliable solution for custom exhaust fabrication where precise length and high-flow capacity are required. Designed for automotive enthusiasts and professional builders, this straight exhaust pipe extension is essential for bridging the gap between headers and mufflers or routing exhaust gases away from the chassis. Its generous 4-inch diameter makes it ideal for high-performance racing setups or heavy-duty diesel applications where minimizing backpressure is critical. By utilizing this extension, builders can achieve a professional-grade exhaust layout without the need for complex custom bending for every straight section.

Constructed from high-quality natural steel, the Schoenfeld 30in Extension 4in Diameter is built to withstand the thermal stresses and vibrations common in performance environments. A key technical feature is the single expanded end, which allows for a seamless slip-fit connection over standard 4-inch tubing, simplifying the welding or clamping process. The 30-inch length provides ample material for long runs, while the 4-inch diameter ensures maximum exhaust velocity and volume for large-displacement engines. The natural finish serves as a clean canvas for those planning to apply high-temp coatings or who require a raw steel surface for secure TIG or MIG welding.

This component is particularly beneficial for those building custom race cars, off-road rigs, or performance trucks that require a robust 4-inch exhaust system. Because it is sold as a single unit, it allows for modular purchasing based on the specific requirements of your unique vehicle modification project. Installation is straightforward for those with fabrication experience, as the expanded end eliminates the need for a separate coupler at one junction. Whether you are looking to buy a replacement section or are reviewing specifications for a new build, this Schoenfeld extension delivers the durability and fitment required for demanding automotive applications.
