Extreme Duty 3" Exhaust - 75/78 Series

When you are towing heavy or grinding up rocky tracks, a restrictive exhaust makes the old 1HZ work harder and run hotter. This Redback Extreme Duty 3-inch system frees up flow so the engine breathes easier and stays cooler.

Built from 409 stainless with thick flanges and extreme-duty hangers, it takes corrugations and vibration without cracking. Choose a straight-through muffler, resonator or muffler-delete to suit the note you want, and monitor temps through the EGT port.

Backed by a 10-year manufacturer warranty.
