The factory exhaust on a 2000-2003 7.3L Powerstroke cab and chassis truck is restrictive, and an old rusted system is a good excuse to fix that. The Diamond Eye K4327A-RP is a 4 inch turbo back system that runs from the turbo to a single passenger side exit and replaces the muffler with a straight pipe for more sound and less restriction.

It is the no-muffler version of the Diamond Eye K4327A, built for F-250 and F-350 Super Duty cab and chassis trucks with the 7.3L Powerstroke.

What you get:

• New 4 inch turbo back exhaust kit from Diamond Eye Performance

• Single exit on the passenger side
• Aluminized steel, Diamond Eye Performance Series
• Fits 2000-2003 Ford F-250 and F-350 Super Duty cab and chassis with the 7.3L Powerstroke
