MBRP Down-Pipe T409

1994–2002 Dodge Ram 2500 / Ram 3500

DS9401

Overview:

The MBRP 4 Down-Pipe T409 is engineered for Dodge Ram 2500 and Ram 3500 trucks from 1994 to 2002, designed to enhance exhaust flow and maximize turbo efficiency. This high-quality down-pipe is ideal for enthusiasts who demand more power and improved performance from their diesel trucks. By replacing the restrictive factory down-pipe, it allows exhaust gases to exit more freely, resulting in increased horsepower and torque while lowering exhaust gas temperatures (EGTs).

Built for those who push their trucks beyond stock limits, the MBRP down-pipe provides a direct, unrestricted path from the turbocharger to the exhaust system, helping you achieve a more responsive and powerful driving experience.

Key Features:

Designed with precision and durability in mind, the MBRP 4 Down-Pipe T409 offers the following key benefits:

• Constructed from premium T409 stainless steel for superior corrosion resistance and longevity
• 4-inch diameter tubing to maximize exhaust flow and reduce backpressure
• Includes a 4-inch dual wall exhaust tip for enhanced durability and style
• Jig manufactured to ensure precise fitment and ease of installation
• Significantly lowers exhaust gas temperatures, protecting turbo components
• Increases horsepower and torque output for improved overall performance
• Compatible with Dodge Ram 2500 and 3500 models from 1994 through 2002
• Not recommended for vehicles equipped with catalytic converters (partial 1998 model year)

Construction & Design:

The down-pipe is expertly crafted from T409 stainless steel, a material known for its excellent strength and resistance to rust and corrosion under extreme heat conditions. This ensures long-lasting durability even in demanding diesel truck environments. The 4-inch dual wall tip adds a rugged, polished look while providing additional protection against heat and wear.

MBRP employs jig manufacturing techniques to guarantee that each down-pipe fits perfectly, minimizing installation challenges and ensuring optimal exhaust flow alignment with the turbocharger and exhaust system.

Performance & Sound

By increasing exhaust flow efficiency, the MBRP down-pipe helps reduce turbo lag and lowers exhaust gas temperatures, which can extend the life of your turbocharger. The improved flow dynamics translate into noticeable gains in horsepower and torque, enhancing towing capability and overall engine responsiveness.

While primarily focused on performance, the down-pipe also contributes to a deeper, more aggressive exhaust note, giving your Dodge Ram a commanding presence on the road.

Installation & Fitment:

This down-pipe is designed for direct bolt-on installation on 1994–2002 Dodge Ram 2500 and 3500 models. The precise jig manufacturing ensures a perfect fit with factory mounting points and turbocharger outlets. Installation typically requires basic hand tools and moderate mechanical experience. Note that this part is not compatible with vehicles equipped with catalytic converters, particularly some partial 1998 model year trucks.

What's Included:

• MBRP 4-inch Down-Pipe T409 stainless steel assembly
• 4-inch dual wall exhaust tip
• Installation hardware and gaskets (where applicable)
• Detailed installation instructions

Ideal For:

This down-pipe is perfect for Dodge Ram 2500 and 3500 owners seeking to upgrade their exhaust system for enhanced power and durability. It is especially suited for diesel truck enthusiasts who tow heavy loads, participate in off-road activities, or simply want to improve their truck’s performance and sound without extensive modifications.
