aFe Twisted Steel Loop Delete Down-Pipe

2007–2018 Jeep Wrangler JK 3.6L V6

Part #: 48-06209

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 improved exhaust flow and clearance. It is an essential upgrade for Jeep owners who have installed or plan to install long-arm travel lift kits that interfere with the original equipment (OE) loop design.

Constructed from durable aluminized steel and mandrel-bent for optimal flow, this down-pipe offers a balance of performance, longevity, and value. It is compatible with both the factory "y-pipe" and aFe Power's own "y-pipes," making it a versatile choice for various exhaust setups on the Jeep Wrangler JK platform.

Key Features

Engineered to enhance exhaust flow and accommodate suspension modifications, the aFe Twisted Steel Loop Delete Down-Pipe offers the following key features:

• Mandrel-bent aluminized steel construction for durability and smooth exhaust flow
• Eliminates the restrictive stock loop section after the catalytic converter
• Designed to provide clearance for long-arm travel lift kits that interfere with the OE loop
• Compatible with both stock "y-pipes" and aFe Power "y-pipes"
• Fits both 2-door and 4-door Jeep Wrangler JK models
• Offers a cost-effective upgrade without compromising quality or functionality
• Manufactured in aFe’s Corona, California facility ensuring high-quality standards

Construction & Design

This down-pipe is crafted from aluminized steel, which provides excellent corrosion resistance and durability under harsh driving conditions. The mandrel-bent tubing ensures smooth bends that maintain consistent diameter throughout, reducing exhaust turbulence and backpressure. This design not only improves exhaust flow but also enhances the overall efficiency of the exhaust system.

The loop delete design removes the factory’s restrictive loop section, which is often problematic when installing suspension lift kits with extended travel arms. By eliminating this section, the down-pipe prevents interference and potential damage, allowing for greater suspension articulation and improved off-road capability.

Installation & Fitment

The aFe Twisted Steel Loop Delete Down-Pipe is a direct-fit replacement designed for the Jeep Wrangler JK 3.6L V6 models from 2007 to 2018. Installation is straightforward and typically requires no modifications to the vehicle’s exhaust system. It bolts directly to the catalytic converter and mates seamlessly with the existing or upgraded "y-pipe."

This product fits both 2-door and 4-door Wrangler JK variants, making it a versatile option for most JK owners. It is especially beneficial for those who have installed or plan to install long-arm travel lift kits that interfere with the stock loop section.
