Another Satisfied G-Sport Customer!

We’re usually busy engineering performance to brag about it… but maybe it’s time we started.

Case in point: One of our customers just breezed through vehicle inspection - all systems ready within 100 miles, zero issues passing - while running a setup that’s made 930 RWHP on a 2019 Mustang GT.

High-flow performance and EPA compliance? Yeah, we’ll talk about that.

Tag us in your builds to be shared in the future!

Learn why builders choose our leading GSport High-Performance Cats-

“Our earlier tests showed no power loss at all when running the GESI 400-cpi cats, so they’re staying on the car. We made well over 800 rwhp through the cats”

Perfect turbocharger/engine pairing unlocks more than 100 horsepower in a bolt-on LS3 engine.
