Borla CrateMuffler ATAK 2.5-Inch Offset Inlet to 2.5-Inch Offset Outlet T-304 Stainless Steel Oval Muffler for Ford Coyote 5.0L V8 (400858)
Unlock ultimate exhaust flow and aggressive acoustic tuning with the Borla CrateMuffler ATAK Performance Muffler. Masterfully engineered to meet the specific engine mapped acoustic requirements of Ford Coyote 5.0L V8 configurations, this is the world's first muffler purpose built to optimize the sound and power of crate and custom built motors. This highly efficient specialty unit features a 2.5-inch offset inlet and 2.5-inch offset outlet configuration optimized for moderate output Ford platforms. At its mechanical core, this premium performance muffler breaks away from restrictive traditional baffle layouts by incorporating Borla's cutting edge straight through internal geometry tailored for specific engine displacement resonance frequencies. This innovative layout features a high velocity perforation core that optimizes gas flow and exhaust velocity, generating an excellent scavenger effect. This advanced aerodynamic design maximizes peak horsepower, expands torque delivery, and completely eliminates backpressure bottlenecks for optimized performance configurations.
The structural engineering of the Borla 400858 addresses long term durability and installation problems beneath harsh track and street conditions through a 100% welded, heavy gauge setup. Enclosed in a compact 6-inch by 10.34-inch oval by 12-inch long barrel case with a total 16-inch overall footprint, this robust assembly delivers excellent space optimization when tucked into tight muscle car floors, classic truck frames, or street rod undercarriages. The specialized straight through body layout features an engine specific directional design, which utilizes a built in structural mounting bracket welded directly to the outlet end cap face for fast identification and rock solid exhaust hanging. This internal matrix is precision tuned to dramatically reduce or completely eliminate annoying cabin drone on the specified engine families while delivering Borla's highest, most aggressive ATAK sound level under full throttle. Built completely from CNC machined, aircraft quality, premium grade T-304 austenitic stainless steel, this heavy duty canister provides absolute maximum resistance against corrosion and thermal fatigue. Delivering bulletproof structural stability backed by Borla's legendary Million Mile warranty, this unit delivers a raw, high velocity acoustic profile for builders who demand a track inspired volume level without compromising internal comfort.
Straight Through Flow Dynamics & Engine Specific Tuning: Unlike basic factory replacements, universal multi chambered mufflers, or generic parts that choke velocity and create harsh drone frequencies, this CrateMuffler is acoustic mapped to the firing orders and pressure pulses of Ford moderate output Coyote V8s. The offset to offset routing geometry allows builders to slide right into original vehicle channels while using precise internal perforation matrices to break down high energy sound waves without placing a physical restriction in the path of the thermal gas exit.
Fabrication Installation Guideline Note: This high performance universal CrateMuffler is a highly specialized directional component that must be oriented correctly to function as engineered. The outlet side is clearly identified by a heavy duty factory mounting bracket welded directly onto the end cap casing. This model is built with smooth, unnotched attachment collars engineered explicitly for a permanent, clean weld on installation by a professional fabricator.

Detailed Fitment Breakdown & Application Models
Universal Fitment Parameters & Structural Boundaries:
This premium CrateMuffler performance ATAK muffler does not feature a traditional direct year, make, and model automotive catalog listing. Instead, it is a specialized **Universal Fit** component specifically targeted and engineered for custom vehicle platforms powered by the Ford Coyote engine family. It is intended for custom adaptation, hot rods, restomods, custom street cars, classic trucks, and racing vehicles using custom exhaust layouts.
Target Engine Family Compatibility:
- Ford Coyote 5.0L Moderate Output V8 Engines (Including Gen 1, Gen 2, and Gen 3 Coyote blocks)
- Commonly utilized in custom restomod builds and crate engine swaps originally adapted from vehicle families such as the Ford Mustang GT and Ford F-150
- Ideally suited for custom fabricated projects requiring a dual muffler configuration (Note: Two mufflers are required for dual exhaust setups)
Sizing, Connection & Dimensional Details:
Fits your project layout across these exact structural specifications:
- Inlet Connection Size: 2.50-Inch internal diameter offset port neck
- Outlet Connection Size: 2.50-Inch internal diameter offset port neck (with integrated mounting bracket)
- Muffler Case Configuration: 6.00-Inch x 10.34-Inch custom oval structural shape
- Muffler Case Body Length: 12.00 Inches of primary engine tuned sound suppression coverage
- Overall Muffler Total Length: 16.00 Inches from inlet tip to outlet tip boundary
- Internal Architecture Matrix: Directional straight through high flow performance configuration mapped for Ford harmonic frequencies
- Material Grade Composition: Authentic T-304 Austenitic Stainless Steel with a natural mill finish
Important Application Notes:
* Premium Materials: Built entirely with authentic T-304 stainless steel to deliver superior rust resistance and durability over lower grade T-400 series or aluminized hardware choices.
* Directional Requirements: This is a directional flow component. Do not reverse mount this muffler; the end cap with the pre welded mounting bracket must always face the rear exit of the vehicle.
* Fabrication Requirements: Features smooth, unnotched collars engineered for weld-in installation. Professional fabrication and welding adjustments are necessary for a perfect undercar fit.
