MBRP 88-93 Dodge 2500/3500 Cummins 5.9L 4WD ONLY Turbo Back Single Side Exit P Series Exhaust

SKU: S6150P / UPC: 882963117687

MBRP 4-Inch Turbo-Back Exhaust System for 1988-1993 Dodge Ram 2500/3500 Cummins 5.9L Diesel 4WD 

The MBRP turbo-back exhaust system is a complete 4-inch single side exit setup replaces the restrictive factory exhaust from the turbo outlet all the way back, delivering noticeable gains in horsepower, torque, and overall drivability that put it ahead of stock configurations and competing aftermarket options. Drivers report up to 18 additional horsepower and 28 ft/lbs more torque, along with reduced exhaust gas temperatures (EGTs) for safer towing and hauling, quicker throttle response, and improved fuel efficiency during daily use or heavy loads.

The aluminized steel construction resists corrosion better than untreated mild steel alternatives, ensuring long-term reliability in demanding conditions without the higher cost of full stainless systems.
