SPD Performance HX Series Pre-Axle Dump Exhaust – 2021-2026 Ford Raptor / Raptor R

SPD Performance HX Series Pre-Axle Dump — Dual Valved Exhaust
2021-2026 Ford Raptor (3.5L HO EcoBoost) / 2023-2026 Raptor R (5.2L SC V8)

The Ultimate Off-Road Exhaust. All Four Modes. No Compromise.

SPD Performance Inc. introduces the newest evolution of our proven HX Series platform — the HX Series Pre-Axle Dump. Built specifically for off-road enthusiasts, this system eliminates the vulnerable over-axle tailpipes for maximum departure angle, ground clearance, and durability, while retaining full factory valve control.

Based on our flagship HX Series Valved Muffler Upgrade, the Pre-Axle Dump is engineered for trucks running aftermarket high-performance downpipes, Alpha Cats, or headers.

Built for the Dirt. Quiet When You Need It.

Unlike standard dump or race mufflers that are loud 100% of the time, our Pre-Axle Dump uses dual OEM-style valves with isolated True Bypass Technology.

• Quiet & Normal Modes — routed through the straight-through HX Series muffler for a deep, refined tone with no rasp, drone, or harmonic vibration. HOA-safe for cold starts and highway drives.
• Sport & Baja Modes — dual valves open, bypassing the muffler for max flow and the aggressive, exotic note the Gen3 platform is known for when paired with SPD downpipes.

Permanently solves the factory valve and muffler rattle issue.

Key Features

• Off-Road Focused Pre-Axle Dump Design — eliminates over-axle tailpipes that get crushed on rocks, whoops, and tight departure angles. Maximum clearance for long-travel and chase racks.
• Dual Valved True Bypass Technology — isolated dual-muffler design prevents harmonic vibration and drone. Truly quiet in Quiet/Normal.
• Retains All 4 Factory Exhaust Modes — Quiet, Normal, Sport, Baja function exactly as Ford intended. No valve reprogramming needed.
• Significant Weight Savings — removes 30+ lbs of factory muffler and tailpipes.
• No Rasp, No Rattle — deep, refined tones engineered out the rasp and OEM muffler rattle associated with high-flow downpipes.
• Plug-N-Play — direct replacement for the factory valved muffler system. Includes factory-style valve actuators and hangers. No cutting, no tuning required.
