They did the math...a little reminder on flow numbers with high-performance cats vs. straight pipe applications.

Great info from Greg!

Greg Banish of Calibrated Success discusses a recent experiment he conducted on how to keep your horsepower gains on modified vehicles, with aftermarket cats...

Lots of People Say, “Just Go Catless.”

Here’s what actually happens:

•Post-cat O2 sensor immediately reads zero catalyst efficiency → P0420 code → CEL on.
•Removing the cat drops turbine back-pressure → your wastegate loses authority → boost overshoots → your OTS tune is no longer calibrated for your setup.
•O2 sensors run hotter and work harder without the thermal buffer of the cat → accelerated wear.
•Without a custom tune that disables O2 monitoring, you’re fighting the car every time you drive it.
•Fails OBD emissions inspection in most states.

The real-world HP gap between a properly spec’d G-Sport high-flow cat and catless? Roughly 5–10hp at most, depending on platform, often within dyno margin of error.

G-Sport GEN2 at 400 CPSI gives your ECU exactly what it needs, keeps your OTS tune stable, and is rated to 1,200hp. Performance without the compromises nobody warned you about.

Straight Pipe or High-Flow Cat?

Here’s what engineered performance actually delivers:

✅Power: Modern high-flow ≠ restriction

✅Sound: Aggressive without rasp or drone

✅Durability: Built to withstand extreme heat and high-load conditions

G-Sport High-Flow Cats are engineered for performance where it matters most.

Same performance mindset. Just smarter ex*****on.

Whether you’re building or integrating, there’s a reason more systems start with G-Sport
