CNC-bent pipes ensure uniform geometry and precise fitment to the original mounting points. Installation is straightforward and follows the plug \u0026amp; play principle. All joints are TIG welded under argon gas shielding, ensuring clean, finished, and fully sealed weld seams – this is essential for long-term durability.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eCNC-machined 10 mm\u003c\/span\u003e\u003cspan\u003e thick flanges are used at the connection points.
