You might love the look and sound of your flame-tune, but is it killing your catalytic converter (CAT)?

In this interview, Matt Latino from G-Sport by GESi explains the limitations of factory catalytic converters and why performance builds often require something more capable.

G-Sport’s aftermarket catalytic converters are EPA-compliant, stainless steel, and designed for high horsepower, but they’re not indestructible. Matt dives into the real-world causes of CAT failures, including improper sizing, rich tuning, and aggressive launch control or anti-lag strategies. Burble, flame, and pop tunes might be fun, but they push unburnt fuel through your exhaust and straight into your catalytic converter — which can result in thermal overload or even complete failure.

Like tyres on a track day, pushing your CATS too far too often will shorten their lifespan dramatically. Matt shares practical advice on how to make power in a street car while keeping your CAT alive, and what makes GESi’s designs different from cheaper OEM-style ceramic core converters.

Many exhaust specialists already include the likes of G-Sport CATS in their complete systems, so it's possible you might even have one and be benefiting from the performance gains.

Will carbs on V8 hotrods etc become a thing of the past when some alternatives are this easy?

For those unfamiliar with ECU tuning, switching from a carburettor (carb) to EFI can seem daunting, but it doesn't have to be. The ‪@EdelbrockUSA‬ Pro-Flo 4 is designed to make the transition as simple and hassle-free as possible. With pre-calibrated sensors, a self-tuning system, and an easy-to-use app, this sequential port injection system eliminates the need for a laptop, making it one of the most user-friendly EFI solutions on the market with plug-and-play options for the Gen 3 or 4 LS, Gen 1 or 2 Ford Coyote and Chrysler Gen 3 HEMI V8's.

Unlike traditional throttle body injection (TBI) systems that mimic a carb, the Pro-Flo 4 offers true multi-point injection, improving fuel atomization, drivability, and efficiency. Injector and fuel system selection are simplified, with kits available for different power levels, and installation is made easy with a fully terminated wiring harness that requires no crimping or cutting. The distributor-based ignition system means there's no need for an additional crank trigger, further reducing complexity.

The system features closed-loop control that continually learns and adapts while driving, improving fuel mapping in real-time. For those worried about fine-tuning aspects like cold starts and transient enrichment, the Edelbrock E-Tuner App provides intuitive adjustments using familiar carburetor-style terminology. This ensures that even those new to EFI can confidently dial in their setup.

Brad shares his unique journey into motorsport, beginning with his determination to break into the high-stakes world of IndyCar — despite living on the other side of the planet. He dives into the challenges of performance engineering in a tightly regulated series and explains how teams still find speed in the most unlikely places.

From there, Brad transitions to Australia’s V8 Supercars, where he played a key role in a multi-championship-winning team. With firsthand insight, he breaks down what makes this series one of the most intense and exciting in global motorsport.

Brad’s career then takes a surprising turn as he shifts into the world of sustainable transport. Are EVs actually a con? Is there a future where performance and environmental responsibility can coexist? Brad shares his perspective.

Packed with talk on race car electronics, systems engineering, race strategy, and the future of speed, this episode is a great listen.
