Precision-engineered specifically to handle the massive volumetric gas demands, thermal loads, and scavenge targets of the naturally aspirated 5.7 Litre Hemi V8 engine configuration (Petrol EZH V8 16V OHV VVT MPFI putting out 294kW), this premium full system upgrades your vehicle footprint from the engine exhaust ports right down to the rear bumper fascia. Custom-contoured to map cleanly around the massive transmission tunnel, underbody clearance zones, and multi-link coil or air suspension geometry unique to the late-model DT generation platform, it provides an uncompromised full-bore pathway. By pairing race-proven, long tuned length 1 7\/8\" 4-into-1 primary extractors with high-flow catalytic converters and smooth, mandrel-bent 3-inch plumbing, it obliterates system backpressure to deliver rapid acceleration and crisp throttle response. As Australia’s premium exhaust innovator, Pacemaker coats this system in its iconic signature high-temp black exhaust paint and integrates patented rolled end-cap double-skinned stainless steel mufflers, emitting a deep, throaty classic V8 growl on throttle while filtering out uncomfortable cabin boom at cruising speeds. The system terminates in massive, adjustable 5-inch exhaust tips designed to seat seamlessly inside factory rear valence openings. \u003cem style=\"color: #222222 !important;\"\u003eNote: Fits DT Model RAM 1500 5.7L Hemi variants (2021–Present), including all local HSV and ASV remanufactured right-hand-drive conversions featuring factory cutout rear bumpers;
