Pacemaker 3" Performance Exhaust System with 1-7/8" Tuned Headers for RAM 1500 DT 5.7L Hemi V8 2021+ - PP2662-15

Pacemaker Full 3" Performance Exhaust System with 1 7/8" Tuned Headers & Rear Muffler Kit for RAM 1500 DT (5.7L Hemi V8) - PP2662-15

Unleash the full acoustic potential and uncompromised low-end torque of your american small-block powerplant with the Pacemaker Sport Systems heavy-duty complete 3-inch performance exhaust solution featuring full tuned length primary headers. 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. Note: 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; does not fit the supercharged 6.2L TRX variant or older DS model configurations without revision.

Features:

Precision-manufactured in Australia to deliver a definitive horsepower upgrade, maximum cylinder scavenging, and an authoritative, drone-free V8 rumble for the premium DT-series pickup truck platform.

• Complete Header-to-Tip System: Comprehensive high-efficiency track-and-street performance line including long primary extractors, performance catalytic converters, intermediate piping, and dual rear mufflers.
• Tuned Length Extractors: Features precision-formed 4-into-1 headers with large-bore 1 7/8" primary tubes meticulously tuned to optimize cylinder exhausting metrics and mid-range torque fields.
• Signature Finish Coating: Entire header and collector structural path is finished in Pacemaker's premium signature high-temperature black exhaust paint to minimize thermal radiating footprints under the hood.
• Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior structural longevity under intense operating stresses.
• Mandrel Bent Tubing: Rigid high-flow 3" (76.2mm) pipe structure guarantees a smooth, uniform internal diameter through all bends to eliminate gas turbulence and prevent flow restriction.
• Rolled End-Cap Mufflers: Heavy-duty double-skinned stainless steel mufflers offer premium outer case reinforcement, preventing case distortion and internal packing blowout.
• Massive Adjustable 5" Tips: Includes large dual 5-inch adjustable tailpipe tips to ensure custom, flush alignment inside your truck's factory rear bumper trim profiles.

Important Fitment & Installation Notes:

• Specifically engineered to fit DT Model Dodge RAM 1500 pickup trucks equipped with the naturally aspirated 5.4L or 5.7L Hemi V8 petrol engine (2021, 2022, 2023, 2024 to current generations).
• Chassis Conversion Compatibility: Explicitly mapped out to suit right-hand-drive (RHD) remanufactured and converted utility specs managed across Australia and New Zealand, matching all official HSV and ASV engineering tracks.
• Bumper Cutout Prerequisite: The massive dual 5-inch adjustable performance tips are sized exclusively to locate inside original equipment bumpers featuring matching lower exhaust tunnel profile reliefs. Not suitable for flush, commercial base steel bumper configurations lacking exhaust exit openings.
• Oil Filter Clearance Mapping: Pacemaker long tuned headers are built with geometry explicitly designed to run clear of front-mounted engine oil filter positions. While this is the standard setup for the DT platform, ensure filter location metrics prior to staging. (Rear-mounted assemblies require separate relocation plumbing blocks, a scenario mostly found on older DS versions).
• Engine Management Calibration: Following the complete optimization of exhaust backpressure thresholds via full headers and advanced converters, Pacemaker strongly recommends performing an aftermarket ECU software calibration tuning upgrade to avoid check-engine lights and maximize powertrain performance.
• TRX Safety Exclusion: This part number is structured exclusively for naturally aspirated multi-point injected 5.7L builds; it WILL NOT FIT or clear the engine bay footprints of the supercharged 6.2L RAM TRX platform.
• Professional automotive performance technician installation is highly recommended to guarantee ideal ground clearance, strict engine bay steering line tolerances, and gas-tight structural seals under the floor pan.
