Each UEL header features CNC-mandrel bent tubing and handmade piecut bends. Each header is then expertly TIG-welded by hand. Although handmade, each is still manufactured to precise standards and specifications ensuring fitment and performance across each batch. Masterful TIG-welding maximizes strength and durability against cracks and exhaust leaks. The final product quality and finish are undeniable and arguably the best in the market.
