Flo~Pro 4" Turbo Back Single Exhaust | 1989-1993 Dodge Ram 2500/3500 5.9L Cummins

The Flo~Pro 4" Turbo Back Single Exhaust is a direct-fit exhaust upgrade built specifically for the 1989-1993 Dodge Ram 2500/3500 5.9L Cummins. Fabricated in Alberta, Canada from U.S.-sourced heavy-gauge steel tubing, it replaces restrictive factory piping with a full 4" flow path to help lower EGTs, sharpen throttle response and give your diesel a deep, clean, aggressive tone.

What This Turbo Back Does

A turbo-back system replaces everything from the turbocharger outlet to the tailpipe: downpipe, intermediate piping, muffler section and tailpipe. It's the most complete exhaust upgrade you can bolt on, with the biggest gains in airflow and the lowest restriction.

Build It Your Way

This kit is available in the following configurations. Choose the options that fit how you drive:

Material

• 16-Gauge Aluminized Steel: heavy-gauge U.S. steel with a corrosion-resistant aluminized coating. Tough, great value, and ideal for daily driving and towing.
• T409 Stainless Steel: premium U.S.-sourced stainless for superior corrosion resistance and long life through salted winter roads and high-heat towing.

Muffler

• With Muffler: a high-flow muffler keeps the sound deep and aggressive while taking the harsh edge off at highway cruise.
• No Muffler: a straight-through pipe for maximum flow and the loudest, most aggressive diesel sound.
