Finished raw for flexibility in painting or coating, the pipe uses computerized mandrel bends to preserve flow and minimize deformation through the curve. It’s supplied with one flared end to simplify mating to adjacent sections or clamps during installation.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this 45° bend improve a DIY exhaust project?\u003c\/h3\u003e\n\u003cp\u003eThe mandrel-bent curve keeps the internal diameter consistent through the turn, reducing flow restriction and turbulence compared with crushed or poorly formed bends. For custom routing, a precise 45° angle lets you change direction predictably without multiple welded joints.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMandrel-bent to maintain internal shape and improve exhaust flow.\u003c\/li\u003e\n  \u003cli\u003eOne 2.65\" flared opening eases slip-fit connections and clamp placement.\u003c\/li\u003e\n  \u003cli\u003e45° change reduces the need for stacked elbows, lowering welds and potential leak points.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the material and dimensional details I need to know?\u003c\/h3\u003e\n\u003cp\u003eThis section is constructed from 18-gauge mild steel and measures 2.5\" outside diameter, a common size for custom and replacement sections.

Because universal parts require measurement and occasional trimming, they’re best used by hobbyists or professionals comfortable with fabrication.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-fit joints simplify assembly and mock-up without custom flaring equipment.\u003c\/li\u003e\n  \u003cli\u003eRaw finish accepts welding and common surface coatings for corrosion protection.\u003c\/li\u003e\n  \u003cli\u003eUniversal profile suits many exhaust systems but check lengths and diameters first.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? This DNA MOTORING mandrel exhaust tube suits home fabricators, performance hobbyists, and professional shops building or repairing custom exhausts. It’s ideal when you need a reliable 45° offset that preserves flow, reduces fabrication time, and accepts standard exhaust clamps or welds. If you prefer a finished look or require corrosion resistance out of the box, plan to coat or finish the tube after installation. Professional installation is recommended if you’re unsure about fitment, cutting, or welding techniques.\u003c\/p\u003e\n\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this 45° tube compatible with clamp connections?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
