CRG started out making steam pipe manifolds for mostly street car applications to suit larger turbos with external wastegates and required precise packaging to fit under the bonnet.

Chris’s manifolds became extremely sought after on performance street cars, circuit cars, drag cars, ski boats and off road vehicles.

Our manifolds then evolved into full car turbo kits, custom exhaust systems, fabricated aluminium turbo intercooler systems and almost any fabrication required.​ This then led us down the path of working with Titanium for exhaust systems and custom fun stuff like titanium intake and snorkel for Chris’s own Navara

A personal interest in off roading going to K’gari (Fraser Island), Bribie Island, Cape York and regular 4x4s adventures then evolved into finding design flaws and weaknesses in factory manufacturer developed parts then redesigning and developing improved upgrades for cars like the Nissan Navara NP300 D23 (Frontier South America), Isuzu Dmax, Mazda BT-50, Ford Ranger, Holden Colorado and Isuzu NPR and NPS model Trucks,

Our exploration in off roading and camping have lead us down the path of working with Australian companies that are developing and producing some of the best cooling and suspension components around. We work with PWR intercoolers and cooling components, Superior Engineering Suspension, King Springs and King Shocks for Navara and Isuzu Truck upgrades
