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 Solution. 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 [P/N FHXFR21V], the Pre-Axle Dump is meticulously 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 utilizes dual OEM-style valves with our isolated True Bypass Technology.

In Quiet and Normal Modes, exhaust is routed through our straight-through HX Series muffler — producing a deep, refined tone without rasp, drone, or harmonic vibration. It's HOA-safe and perfect for early morning cold starts and long highway drives.

In Sport and Baja Modes, the dual valves open and bypass the muffler for maximum flow and an aggressive, exotic note that the Gen3 platform is known for when paired with SPD downpipes.

This solves the common factory valve and muffler rattle issue permanently.

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: Unlike single-body aftermarket systems, our isolated dual-muffler / bypass design prevents harmonic vibration and drone. Truly quiet in Quiet/Normal.

- Retains All 4 Factory Exhaust Modes: Quiet, Normal, Sport, and Baja function exactly as Ford intended — no valve reprogramming needed.

- Significant Weight Savings: Removes 30+ lbs of factory muffler and tailpipes from the rear of the truck.

- No Rasp, No Rattle: Deep, refined tones engineered to eliminate the rasp and OEM muffler rattle associated with high-flow downpipes.

- Plug-N-Play: Direct replacement for factory valved muffler system. Includes factory-style valve actuators and hangers. No cutting, no tuning required for valve operation.
