Doug Thorley Tri-Y Headers AMC V8 - BJ's Off-Road Exclusive!

Doug Thorley Tri-Y 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. In addition to the high-temp Remflex gaskets provided, 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!!!
