Product Details

Our 4-2-1 headers are a free flowing, mid-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 4-2-1 headers are constructed with 14-gauge mild steel with 3/8 inch thick flanges and V-Band clamps. 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 now available with Y-Pipe for 1980-1991 models.  They also include an Oxygen Sensor Bung and Plug!

**Note: These are currently in production, with our first shipment arriving mid-September.  We will fill existing backorders first, working our way forward.  Please expect a minor delay in these shipping out as we get caught up.  We do allow orders to be placed for customers to 'get in line' and reserve a set.
