As Australia's leading experts in common rail diesel performance, you can trust that your vehicle is in safe hands with us.
We are always pushing the limits of research and development, both in the racing industry and with our own vehicles. This commitment to excellence is why people choose GSL—our expertise speaks for itself. After all, we have the fastest diesel in Australia; it's proof of our deep knowledge and skill.
With every build, we are dedicated to delivering the best possible performance for your vehicle.
We developed Australia’s original 5” dump to 4” stainless steel exhaust system for the Toyota Landcruiser VDJ 76, 78, and 79 Series – and we call it the gamechanger. Want to take it further? Step up to the highly sought-after twin 4” stainless steel exhaust system.
Got a 200 series? No worries – we offer a twin 3” into single 4” system, delivering the best purring twin-turbo 200 series sound you’ve ever heard.
And for 4-cylinder owners, we’ve got you covered too – with our 3” stainless steel exhaust or mild steel options to get your pride and joy sounding just right.
As many know, we don't just offer shiny stainless exhaust systems – we provide a wide range of performance upgrades and trusted brands that we fully support and endorse. We've tested these brands on our own vehicles so you don't have to.
Some of the performance upgrades available at GSL include: front mount intercoolers, thermo fans, turbo upgrades, injectors, crankcase breathers, 4” intake kits, and airbox upgrades.
We also stock and install the following performance products: NPC/All Terrain clutch upgrades, Provent catch cans, Richards Auto lock-up kits, and Safari Armax snorkels.
We’ve saved the best upgrade for last – the ultimate bang for buck – ECU Remapping. And yes, we use master software! This lets us create a custom file specifically for YOUR vehicle, tailoring each remap to perfectly match your rig and lifestyle.
We can remap any common rail diesel, and you won’t be disappointed with the impressive performance gains we’ll unlock for your rig.
