Cat4ward Mid-Length Shorty Header
Replace restrictive, cast-iron stock manifolds with precision built JBA Cat4ward Exhaust Headers
Maximizes exhaust flow for major increases in horsepower, torque and throttle response
Increased exhaust output delivers an overall improvement in power, efficiency and fuel economy
Dyno testing shows typical performance gains on modern, fuel injected V8s to be 10-25hp with similar increases in torque
Pair your headers with a JBA Performance Exhaust system for another 7-10hp
JBA Headers are crafted from either mild or stainless steel (depends on chosen finish)
Mandrel-bent tubing ensures a consistent pipes diameter throughout for unrestricted flow
Over-sized exhaust ports provide enhanced exhaust flow, especially with bored and ported engines
The beefy 3/8" thick, one piece, laser-cut head flanges make for a leak-free seal and easy installation
Patented Firecone collector vastly improves exhaust scavenging for better power, torque and throttle response (depends on model)
