G-Sport

G-Sport Emissions Systems is a series of high-flow catalytic converters from GESi, developed for performance, tuning and motorsport, where exhaust flow, emissions control and reliability need to work together.

G-Sport is especially known for sports catalytic converters and catalytic converter cores for demanding exhaust systems. The products are typically used in downpipes, custom-built exhausts, turbo cars and performance builds, where a standard catalytic converter can be too restrictive or not suitable for high power.

The range includes GEN1 and GEN2 high-flow catalytic converters, High Output and Ultra High Output models, as well as loose cores and accessories for integration into exhaust systems. Several models are developed for high power and high heat load, making them relevant for serious turbo engines and motorsport builds.

One of G-Sport’s strengths is the combination of low restriction, strong flow and emissions reduction. This makes the brand interesting for tuners, workshops and enthusiasts who want to build an exhaust system with better flow without simply removing the catalytic converter completely.

At Qualitec, you will find G-Sport for those who want a serious high-flow catalytic converter for performance, tuning and motorsport. A strong choice when the exhaust needs to be built with focus on flow, durability and correct function under load.
