Would you like a pair of Remflex Gaskets?
Doug Thorley Tri-Y In-Frame Dual headers are a free flowing, full-length design header. These headers increase gas mileage and give your engine more horsepower across the entire rpm range, although they build the most power in the middle rpm range. This makes these headers great for towing and steep grades. The Tri-y headers are constructed with 14-gauge mild steel with 3/8 inch thick flanges and 5/16 in. collector rings. These headers have an o-ring welded into the flange to ensure a leak free seal! Don't forget about the cool sound these add to your rig!!!


These are an in-frame style header for Dual Exhuast (no Y-Pipe used).  

We recommend using our Remflex Gaskets!

**Note: on 1971-1979 Models, you will need to remove the bumpstop for the differential
