For years, exhaust builders have been re-purposing original equipment converters in high performance exhaust applications. Despite the marketing claims, these parts were never designed to meet the needs of performance applications. G-Sport is the only purpose-built, high performance catalytic converter solution.

In response to the increasing demands of California and European Emissions standards, GESi is developing a multi-cell density substrate capable of effectively converting gases at lower temperatures, while still supporting the performance of high horsepower engines when needed. Keep an eye out for this technology in late 2019.
