Constructed from 18-gauge mild steel with a raw natural finish, the piece features a mandrel bend that preserves internal diameter through the curve, helping maintain smooth exhaust flow. One end is flared to 3.15\" ID to allow a straightforward slip-fit connection with other 3\" components, reducing the need for complex adapters during assembly.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the mandrel bend affect performance and fit?\u003c\/h3\u003e\n\u003cp\u003eThe computerized mandrel-bending process maintains tube diameter around the curve, avoiding the internal crimping you see with pressed bends. That smoother internal profile helps minimize turbulence and supports consistent fitment when joining sections in a custom system.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMandrel-bent curve keeps 3\" internal flow path consistent\u003c\/li\u003e\n  \u003cli\u003eComputerized forming reduces distortion and weak points\u003c\/li\u003e\n  \u003cli\u003eBetter alignment and mating with straight sections than crushed bends\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the exact dimensions and connection details I need to know?\u003c\/h3\u003e\n\u003cp\u003eThis elbow is a 90° bend with a nominal 3\" outside diameter and 18-gauge wall thickness, suited for standard 3\" exhaust piping.
