BBK 40520 Shorty Exhaust Header 1991-1999 Jeep 4.0L Polished Silver Ceramic

The BBK 40520 is a high-performance shorty tuned length exhaust header engineered specifically for 1991-1999 Jeep vehicles equipped with the 4.0L inline-six engine. This header features a 1-1/2 inch primary tube diameter designed to improve exhaust flow and increase horsepower and torque throughout the powerband.

Key Features:

• Shorty tuned length design fits applications where full-length headers won't work
• Premium polished silver ceramic coating provides superior heat resistance and corrosion protection
• Keeps underhood temperatures cooler than standard painted or bare metal headers
• 1-1/2 inch mandrel-bent primary tubes maximize exhaust flow
• CNC machined flanges ensure leak-free seal and precise fitment
• Direct bolt-on installation with factory-style connections
• Made from high-quality tubular steel construction

BBK shorty headers are an ideal performance upgrade for Jeep enthusiasts looking to improve throttle response, increase power output, and add an aggressive exhaust note without the complexity of full-length headers. The ceramic coating not only enhances appearance but also helps maintain exhaust gas velocity for improved scavenging and performance.
