Stainless Bros megaphone and transition sections provide a longer, more gradual change in tube diameter than a short reducer cone. This style is useful in exhaust fabrication where a controlled expansion or contraction is desired over a known overall length. Because the geometry affects both packaging and flow area, the inlet size, outlet size, material, wall thickness and overall length are the critical specifications for the build. These components can be trimmed or integrated into custom collectors, exhaust sections and race-oriented fabrication when the dimensions match the intended system.
Fabrication Note: Confirm material grade, tubing size, wall thickness, connection style and all listed dimensions before cutting or welding. Custom-fabrication components are generally not vehicle-specific unless an exact engine, turbocharger or sensor application is stated in the product details.
