Field Report: What’s really KILLING your catalytic converter?

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.

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.------------------------------------TIME STAMPS:0:00 - G-Sport by GESi0:22 - Limitation of Factory Catalytic Converter0:53 - Exhaust Backpressure1:06 - Aftermarket Options2:10 - Aftermarket Vs OEM Construction2:29- Why OEMs Use Ceramic2:39 - Stainless Steel Construction2:50 - Not Bulletproof3:20 - Tuning Mistakes4:00 - Everything In Moderation4:45 - Tyre Analogy5:00 - Thanks Matt!5:30 - BUILD.TUNE.DRIVE
