Unlike traditional billet collectors, our 3D-printed design allows for complex internal geometries that CNC machining simply cannot achieve easily, delivering smoother transitions, enhanced exhaust scavenging, and reduced flow separation.\u003c\/p\u003e\n\u003cp data-start=\"721\" data-end=\"1313\"\u003eEvery detail of the internal collector and transition geometry has been optimized to minimize turbulence, maximize pulse energy, and boost overall exhaust efficiency—all in a compact, high-performance package. Engineered around the ideal merge angle, this collector hits the “sweet spot” for power: the shortest practical transition length that maintains high exhaust velocity and low drag. The result? Stronger mid-range torque, elevated top-end power, and a highly efficient pulse-merging effect that traditional billet collectors just can’t match.\u003c\/p\u003e\n\u003cp data-start=\"1315\" data-end=\"1562\"\u003eDesigned to slip over 54mm (2.13\") OD tubing, with a total overall length of 160mm (from 54mm primaries to 2.5\" outlet), this 3D-printed stainless steel merge collector is the next evolution in exhaust design for serious performance enthusiasts.\u003c\/p\u003e\n\u003cp data-start=\"1315\" data-end=\"1562\"\u003e \u003c\/p\u003e","brand":"LA Fabrication UK","offers":[{"title":"Default Title","offer_id":57498436206917,"sku":null,"price":325.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0883\/1293\/8821\/files\/MC54mmIn-63.5mmOutv5.png?v=1774547828","url":"https:\/\/lafabrication.uk\/products\/4-1-merge-collector-2-13-primaries-3d-printed","provider":"LA Fabrication UK","version":"1.0","type":"link"}
