0711JK38-LTHDR-HSH

Overview:

The Ripp Stainless Steel Long-Tube Header with Catalytic Converters is a premium exhaust upgrade designed specifically for Jeep Wrangler models equipped with the 3.8L engine from 2007 to 2018. Crafted for Jeep enthusiasts seeking enhanced performance and durability, this header system delivers significant horsepower and torque gains while maintaining emissions compliance through included high-flow catalytic converters.

Manufactured in the USA with top-grade materials, this header kit offers a reliable and efficient solution to improve exhaust flow, throttle response, and overall engine output. It is an ideal upgrade for drivers who want to maximize their Wrangler’s power potential without sacrificing quality or longevity.

Key Features:

This long-tube header system combines advanced engineering with robust construction to provide outstanding performance benefits:

• Made from USA-sourced 16-gauge T-304 stainless steel for superior corrosion resistance and strength
• 3/8" thick stainless steel flanges that are ultra-strong and guaranteed never to crack
• Three-piece design for easier installation and precise fitment
• Hand-ported and TIG-welded flanges ensuring smooth, non-turbulent exhaust flow
• 3-to-1 merge collectors that optimize scavenging and exhaust velocity
• Includes two heavy-duty metallic substrate, 200-cell high-flow catalytic converters for emissions compliance without power loss
• Plug-and-play oxygen sensor extensions and O2 bungs for relocating factory sensors
• Compatible with factory heat shields to protect engine bay components
• 2.5" slip-fit connection to existing cat-back exhaust systems for straightforward installation

Construction & Design:

The Ripp long-tube header is expertly engineered using premium T-304 stainless steel sourced from Pennsylvania, ensuring exceptional durability and resistance to rust and heat. The 16-gauge tubing and thick stainless steel flanges provide a robust foundation that withstands the rigors of off-road and daily driving conditions.

The header features a three-piece modular design that simplifies installation and maintenance. Each flange is hand-ported and TIG welded to guarantee a precise seal and smooth exhaust flow. The 3-to-1 merge collectors are carefully calculated to enhance exhaust gas velocity and scavenging effect, improving engine efficiency and power delivery.

Performance & Sound

Installing the Ripp long-tube header on your 3.8L Jeep Wrangler results in an average gain of 26 rear-wheel horsepower and an increase of 20 lb-ft of torque, with torque arriving approximately 600 RPM sooner than stock. This translates to improved throttle response, stronger mid-range power, and a more aggressive exhaust note that enhances the driving experience without excessive drone.

The inclusion of high-flow catalytic converters ensures emissions are properly managed while maintaining optimal exhaust flow, striking a balance between performance and environmental responsibility.

Installation & Fitment:

This header system is designed to fit 2007 through 2018 Jeep Wrangler models equipped with the 3.8L V6 engine. The three-piece construction and slip-fit design allow for a relatively straightforward installation process, compatible with factory heat shields and existing cat-back exhaust systems.

Ripp recommends professional installation by an experienced technician to ensure proper fitment and performance. Additionally, tuning the vehicle after installation is advised to maximize power gains and maintain engine reliability. For models opting to install the optional Hushpower resonator, professional exhaust shop assistance is recommended due to tight fitment, especially on 2-door Wranglers.

What's Included:

• Ripp Stainless Steel Long-Tube Header (three-piece assembly)
