Who We Are

We are GT-Silex - a trusted partner in engineered solutions for sound attenuation and emissions control devices and systems.

Two recognized industry leaders, GT Exhaust and Silex Innovations, joined forces under Nelson Global in 2015 to combine decades of expertise in acoustic and emissions technology. Today, that shared legacy drives us to deliver reliable, high-performance systems for industrial power applications around the world.

Backed by Nelson Global’s engineering and manufacturing network, we offer both standard and custom solutions – from compact tubes to large-scale high horsepower completely integrated aftertreatment and acoustical management systems – all designed for durability, efficiency, and compliance with the most demanding standards.

With every product, we uphold the same promise that has defined Nelson Global for more than 85 years: reliability engineered to perform, and partnership built to last.
