1994-1997.5 Powerstroke 4" Turbo Back Exhaust - No Muffler (421116 / 422125)

Flo-Pro Exhausts are designed to fit all wheelbase & cab configurations unless otherwise specified.

The 421116 & 422125 is a 4" turbo-back exhaust system for the 1994-1997.5 7.3L Powerstroke. It allows you to drop out your restrictive OE piping and replace it with a high-flow 4" straight pipe kit. This exhaust not only sounds great, but it will also improve throttle response, mileage, and lower EGT's in your 7.3L!

Part Number: 421116 & 422125

• 4" Turbo Back Exhaust
• NO Muffler
• Increased Torque & Fuel Mileage
• Aluminized Steel & Stainless Steel Options
• Single Rear Exit

Aluminized steel is the budget-friendly choice. It has a protective coating that holds up well, but once that coating wears it will eventually rust through, especially in salted winter climates. The stainless option is T409 stainless, an automotive-grade steel built to resist rot, and it will typically outlast the truck. T409 is not polished show-grade stainless, so light surface rust or discoloration can still show up over time. That is cosmetic only and won't affect performance or service life.

• Will not fit trucks equipped with dual fuel tanks
