aFe Twisted Steel Loop Delete Pipe

2007–2018 Jeep Wrangler JK 3.6L V6

Part #: 48-46209

Overview

The aFe Twisted Steel Loop Delete Down-Pipe is a precision-engineered exhaust component designed specifically for Jeep Wrangler JK models equipped with the 3.6L V6 engine from 2007 through 2018. This down-pipe replaces the restrictive stock loop section located after the catalytic converter, providing a more direct exhaust path. It is an ideal upgrade for Jeep enthusiasts who have installed long arm travel lift kits that interfere with the original equipment exhaust layout.

By eliminating the loop, this down-pipe improves exhaust flow and clearance, allowing for enhanced suspension articulation without compromising exhaust performance. It is compatible with both the original equipment "Y-Pipe" and the aFe MACH Force XP "Y-Pipe," making it a versatile choice for various exhaust setups.

Key Features

Engineered for durability and performance, the aFe Twisted Steel Loop Delete Pipe offers the following key features:

• Designed to remove the stock exhaust loop section after the catalytic converter for improved clearance
• Compatible with OE "Y-Pipe" and aFe MACH Force XP "Y-Pipe" configurations
• Specifically built to accommodate long arm travel lift kits that interfere with the factory loop
• Constructed from 2.5-inch stainless steel mandrel-bent tubing for optimal flow and strength
• Includes all necessary hardware for installation
• Precision fitment for both 2-door and 4-door Jeep Wrangler JK models
• Manufactured in the USA at aFe’s Corona, California facility

Construction & Design

The aFe Twisted Steel Loop Delete Pipe is crafted from high-quality 2.5-inch stainless steel tubing, mandrel-bent to maintain smooth exhaust flow and minimize turbulence. This robust construction ensures long-lasting corrosion resistance and durability under demanding off-road conditions. The design eliminates the restrictive loop section found on the stock exhaust, providing additional clearance for lifted suspensions and enhanced articulation without sacrificing structural integrity.

Every pipe is precision-engineered to fit seamlessly with the Jeep Wrangler JK’s exhaust system, ensuring a secure and leak-free connection. The inclusion of all necessary hardware simplifies the installation process and guarantees a professional-grade fit.

Installation & Fitment

Installation of the aFe Twisted Steel Loop Delete Pipe requires cutting the factory exhaust to remove the stock loop section. This modification is necessary to properly fit the new down-pipe and achieve the intended clearance benefits. The pipe is designed to fit both 2-door and 4-door Jeep Wrangler JK models equipped with the 3.6L V6 engine from 2007 to 2018.

It accepts either the original equipment "Y-Pipe" or the aFe MACH Force XP "Y-Pipe," providing flexibility depending on your exhaust setup. Professional installation is recommended to ensure proper cutting, fitment, and sealing.
