Nitrous Express (NX) was founded in 1996 with the goal of exceeding existing nitrous systems in performance. The company’s advantage stemmed from a clean slate – their components were built from the ground up with performance modifications already integrated. This offered customers superior results compared to competitors, who often required expensive modifications to achieve similar gains. NX’s initial impact was significant, offering a breath of fresh air to the market. Over the next two decades, they continued to refine their nitrous products while expanding their offerings to include a range of impressive nitrous and water-methanol products.
