aFe Power Twisted Steel 409 Stainless Steel Headers for 2007-2011 Jeep Wrangler JK (V6-3.8L)

Fits 2007-2011 Jeep Wrangler JK models equipped with the V6-3.8L engine.

Replace your restrictive factory exhaust manifolds with aFe Power Twisted Steel headers to unlock performance gains of up to +6 HP and +6 lbs. x ft. of torque. Engineered for durability and maximum exhaust flow, these headers are constructed from 1-1/2-inch 14-gauge 409 stainless steel tubing and feature heavy-duty 3/8-inch laser-cut flanges for a warp-resistant, leak-free seal.

Unlike standard formed collectors that can create turbulence and hinder flow, these headers utilize true mitered collectors. This pulse-control technology increases exhaust velocity and improves throttle response. The mandrel-bent curves maintain a consistent diameter throughout the tube, eliminating restrictions and ensuring smooth exhaust gas evacuation for long-term durability.
