aFe Shorty Headers (Titanium Ceramic)

2021–2025 Jeep Wrangler 6.4L 392

Part #: 48-38031-T

Overview

The aFe Shorty Headers with Titanium Ceramic coating are engineered specifically for the 2021–2025 Jeep Wrangler equipped with the powerful 6.4L 392 engine. Designed to enhance exhaust flow and reduce engine bay temperatures, these headers deliver noticeable performance improvements while maintaining a factory-like fitment. Ideal for Jeep enthusiasts seeking to unlock additional horsepower and torque without compromising reliability or requiring extensive modifications.

Constructed with precision and durability in mind, these headers provide a direct bolt-on upgrade that integrates seamlessly with the factory exhaust system. The titanium ceramic Cerakote finish not only offers superior heat management but also adds a sleek, high-performance aesthetic under the hood.

Key Features

Engineered for performance and durability, the aFe Shorty Headers include the following standout features:

• Up to +11 horsepower and +13 lb-ft of torque gains as verified on aFe’s in-house dyno
• Mandrel-bent 304 stainless steel tubing ranging from 1-7/8 inch to 3 inch for optimized exhaust flow
• Titanium Ceramic Cerakote coating inside and out to reduce surface temperatures and lower engine compartment heat by up to 46%
• Heavy-duty laser-cut, machined mild steel flanges for a durable, leak-free seal
• 4-to-1 mitered merge collectors designed to decrease turbulence and increase exhaust velocity
• 100% MIG-welded construction ensuring race-proven strength and long-lasting durability
• Retains factory oxygen sensor locations for easy integration with stock emissions controls
• Compatible with the factory exhaust system requiring no cutting or modifications
• Computer-aided design for precise, high-tolerance fitment

Construction & Design

The headers are crafted from premium 304 stainless steel tubing, mandrel-bent to maintain consistent diameter and smooth bends that promote unrestricted exhaust flow. The tubing transitions from 1-7/8 inch at the flange to 3 inch at the collector, optimizing scavenging and velocity for improved engine breathing.

Both the interior and exterior surfaces are coated with a titanium ceramic Cerakote finish, which significantly reduces heat radiation. This advanced coating helps lower engine bay temperatures, protecting surrounding components and improving overall thermal efficiency. The use of laser-cut, machined mild steel flanges ensures a precise fit and a secure, leak-free connection to the factory exhaust manifold.

Performance & Sound

By improving exhaust flow dynamics and reducing backpressure, these shorty headers deliver measurable performance gains of up to 11 horsepower and 13 lb-ft of torque. The mitered merge collectors reduce turbulence and enhance exhaust velocity, resulting in sharper throttle response and a more aggressive exhaust note that complements the Jeep Wrangler’s naturally aspirated 6.4L V8 engine.

Installation & Fitment

Designed as a direct bolt-on replacement, the aFe Shorty Headers fit perfectly in the stock locations of the 2021–2025 Jeep Wrangler 6.4L 392 without requiring any cutting, welding, or modifications. The system retains all factory oxygen sensor locations, allowing for straightforward installation and compatibility with the factory exhaust and emissions systems. Installation can be completed with basic hand tools and moderate mechanical experience.
