Custom Buell 1190 Hammerhead Exhaust and Tune

INCLUDED:

Construction & Design

Premium Stainless Steel Fabrication

• Constructed from high-grade stainless steel for maximum durability, corrosion resistance, and heat tolerance

• Precision TIG-welded seams with visible heat-treated coloration (blue/gold tones), showcasing craftsmanship

• Lightweight design compared to OEM systems, reducing overall bike weight

Performance-Oriented Layout

• 2-into-1-into-dual outlet configuration for optimized exhaust scavenging

• Carefully engineered pipe diameters and merge collector to improve exhaust velocity

• Dual slash-cut outlets for balanced flow and aggressive styling

Integrated Resonator / Mid-Chamber

Features a compact mid-chamber resonator to:

• Smooth exhaust pulses
• Reduce unwanted drone
• Maintain deep, race-inspired tone

Mounting & Hardware

Included in the system:

• Custom fabricated mounting bracket for secure chassis attachment

• Full hardware kit (clamps, springs, fasteners) for installation

Designed as a direct-fit performance upgrade, compatible with the factory header routing or aftermarket header setups.

Performance Gains

When paired with a proper ECU tune, this system delivers:

• Increased horsepower & torque across the RPM range

• Noticeably improved midrange acceleration

• Faster throttle response and reduced engine restriction

• Enhanced top-end pull for the track

The freer-flowing design allows the 1190cc V-twin to breathe more efficiently than the restrictive stock exhaust.

Custom ECU Tune (Critical Component)

To fully realize the benefits of this exhaust, a custom fuel and ignition tune is required.

Tune Enhancements:

• Optimized air/fuel ratios for the new exhaust flow

• Adjusted ignition timing for stronger combustion efficiency

• Removal or recalibration of factory restrictions

• Smoother power delivery with reduced hesitation

This ensures the engine runs:

• Cooler

• Stronger

• More efficiently

Sound Profile

• Deep, aggressive V-twin rumble at idle

• Sharp, race-inspired bark under throttle

• Balanced tone thanks to the mid-chamber—no harsh rasp
  

Aesthetic & Visual Impact

• Raw stainless finish with heat coloration = race bike look
  

• Clean welds and handcrafted appearance elevate the bike’s custom appeal

Ideal Use

• Performance builds

• Track day setups

• High-end custom Buell builds

• Riders looking to stand out visually and audibly

Summary

This custom stainless exhaust and tune package transforms the Buell 1190 Hammerhead from an already elite American superbike into a true race-bred machine—delivering more power, sharper response, and a sound that matches its aggressive DNA.
