BBK 1615 Titanium Ceramic Shorty Headers for 1996-2004 Ford Mustang GT 4.6L 2V

Vehicle Fitment

• 1996-2004 Ford Mustang GT (SN95/New Edge, 4.6L 2V SOHC V8, Coupe & Convertible, All GT Trims, Automatic & Manual)
• 2001 Ford Mustang Bullitt (SN95/New Edge, 4.6L 2V SOHC V8, Coupe)

Fitment Notes

• Does NOT fit 1996-2004 Ford Mustang SVT Cobra - the Cobra uses a 4.6L DOHC 4V engine with different exhaust port geometry. A separate BBK header is required for Cobra applications.
• Does NOT fit 2003-2004 Ford Mustang Mach 1 - the Mach 1 also uses a 4.6L DOHC 4V engine and requires a different header. See BBK's dedicated Mach 1 fitment SKU.
• Specific to the 4.6L 2-valve SOHC V8 engine only - confirm engine configuration before ordering.
• Direct bolt-on to the stock factory mid-pipe or any BBK standard-length mid-pipe - no cutting, welding, or modifications required.
• CARB Certified (EO# D-245-16): 50-state legal for all 1996-2004 Ford Mustang 4.6L GT applications.
• Designed to fit the vehicle as delivered from the factory. If the vehicle uses aftermarket cylinder heads, motor mounts, chassis components, or custom-modified parts, it is the installer's responsibility to verify fitment before installation.
• Sold as a set (pair) - includes both left and right headers.
• Light-to-moderate mechanical skill required for installation.

Features

• Equal-length tuned shorty header design replaces the restrictive factory cast iron exhaust manifolds with wider 1-5/8" primary tubing, delivering dyno-verified gains of 8-15+ rear wheel horsepower and torque through improved exhaust scavenging and balanced flow across all eight cylinders.
• 1-5/8" CNC mandrel-bent primary tubes maintain a perfectly round cross-section through every bend - eliminating the turbulence and restriction caused by the factory cast iron manifold passages and improving exhaust gas velocity across the full RPM range.
• Equal-length primary design ensures balanced exhaust flow from all eight cylinders to the collector, maximizing scavenging pulse efficiency for consistent power gains across the powerband.
• 3/8" one-piece laser-cut die-stamped header flanges deliver superior rigidity over stamped multi-piece or thin-gauge flanges - resisting warping through heat cycles and ensuring a guaranteed leak-free cylinder head seal.
• Titanium ceramic finish provides heat resistance, corrosion resistance, and long-term appearance retention - holds radiated heat inside the header to reduce underhood temperatures and contributes to improved density in the intake charge.
• All headers are robotically and precision hand-welded, then pressure-tested at the factory before shipment to confirm a leak-free, structurally sound assembly out of the box.
• CAD-designed and dyno-developed at BBK's own Southern California facility specifically for the 1996-2004 4.6L 2V GT platform - not a generic shared-platform design.
• BBK tuned length design improves exhaust scavenging wave timing over equal-length or stock-length manifolds for gains in both performance and fuel economy over stock.
• Compatible with the factory stock mid-pipe or any aftermarket standard-length mid-pipe for maximum flexibility in completing the exhaust system.
• Made in the USA - BBK has manufactured performance exhaust headers domestically since 1988.

Product Description

The BBK Performance 1615 Titanium Ceramic Shorty Tuned Length Headers are a direct bolt-on performance upgrade engineered specifically for the 1996-2004 Ford Mustang GT and 2001 Bullitt equipped with the 4.6L 2-valve SOHC V8. Designed and dyno-tested at BBK's Southern California facility, these equal-length shorty headers replace the factory's restrictive and heavy cast iron exhaust manifolds with 1-5/8" CNC mandrel-bent 16-gauge steel primaries that deliver dramatically improved exhaust flow, balanced pulse timing across all eight cylinders, and dyno-verified gains of 8-15+ rear wheel horsepower and torque over stock. The equal-length primary configuration ensures that scavenging pulses from all cylinders arrive at the collector in sync, maximizing efficiency and producing a more consistent power curve compared to unequal-length designs.

Construction quality is built to BBK's CNC-Series standard: 3/8" one-piece laser-cut die-stamped flanges resist warping through repeated heat cycles and guarantee a leak-free cylinder head seal, while every header is robotically and precision hand-welded before undergoing a full pressure test at the factory. The titanium ceramic coating reduces radiated heat into the engine bay, protects against corrosion and rust, and maintains appearance under sustained high-heat use - contributing to lower underhood temperatures and improved intake charge density. The system bolts directly to the stock factory mid-pipe on all GT models in both automatic and manual configurations, and all installation hardware including header bolts, studs, and fresh gaskets are included.

Critical fitment note: these headers are engineered specifically for the 4.6L 2-valve SOHC V8 found in the GT and Bullitt. They will not fit the SVT Cobra or Mach 1 Mustang, both of which use a 4.6L DOHC 4V engine with different exhaust port configuration - separate BBK header SKUs are available for those platforms. CARB Executive Order D-245-16 certifies this system as fully 50-state legal for all 1996-2004 Mustang GT 4.6L applications. Made in the USA and backed by BBK's 1-year manufacturer's warranty, the 1615 is one of the most popular and proven shorty header options available for the SN95/New Edge 4.6L GT platform.
