aFe Shorty Headers 409 Twisted Stainless Steel 3.8L Jeep Wrangler JK 2007-2011

These aFe Shorty Headers (48-48023) bolt directly onto your 2007-2011 Jeep JK Wrangler with a 3.8L Engine. They're made of 1-1/2" 14-gauge 409 twisted stainless steel tubing with smooth curves and increased diameter for unrestricted flow. You'd better get your toolkit out! Impressive torque, horsepower, and throttle response await.

Features and Benefits:
- Heavy-Duty Flanges for a Leak-Free Seal 
- Better Horsepower, Torque, and Throttle Response
- No Cutting or Drilling Required 
- Smooth Curves and Increased Tube Diameter 
- Mitered Collectors for True Pulse Control Technology 
- Decreased Turbulence and Increased Exhaust Velocity 

aFe's Headers deliver +6 HP and +6 lbs. x ft. torque over the factory exhaust manifolds. You may have noticed that formed collectors are prone to turbulence and hindered flow. Too much dead space is usually the culprit. That's why aFe uses true mitered collectors with true pulse control technology. They eliminate dead space, improving flow and performance.

The Shorty Headers use heavy-duty 3/8" thick flanges to prevent warpage and ensure a leak-free seal. These Headers will retain your stock catalytic converters.      

Tech Tip: aFe recommends purchasing spark plug wire boot protectors and gaskets (P/N: 4890004) for additional protection and a hassle-free installation. Spark plug boot protectors provide up to 1600F protection for your spark plug wires. Gaskets ensure a leak-free seal for a hassle-free installation.
