VF Calais Wakes Up with a Fresh High‑Flow Cat Upgrade

The VF Calais gets a tidy upgrade with a freshly added high‑flow cat built into the existing assembly. The factory setup wasn’t rattly — just breathing through a straw — so the old section was cut open and the new cat welded in to finally let the thing exhale. While we were in there, we also cleared out two hidden restrictions in the intermediate assemblies — little factory choke points — so the new high‑flow cat could actually do its job properly. The video explains what had to happen and why: the measurements, the alignment, and how the upgraded section was built, even though the cutting and welding aren’t shown on camera. Once fitted, the Calais feels instantly happier. Sharper throttle, smoother revs, and a deeper note without touching the tune. A clean upgrade that stops the old girl sounding like she’s doing yoga breathing exercises. #VFCalais #HoldenVF #ExhaustUpgrade #HighFlowCat #FabricatedCat #WorkshopLife #AussieCarCulture #HoldenNation #CalaisLife #PerformanceUpgrade #CarModsAustralia #AussieWorkshop #V6Holden #CustomExhaust
