DIY – How to Repair Rusted Exhaust Header Flange Using a Split Flange Adapter – Chevy Truck Vortec

In this video I repair a leaky header pipe that was due to the header flange and doughnut (donut) gasket. The header flange had basically rusted away, so I opted to use the three hole split flange and a new header donut to repair this leaky exhaust. Ithe vehicle in this video is a 1998 Chevy K1500 Silverado with a 5.7 liter Vortec 350. The process I used in this video will be the same of similar on many other vehicles including GM, Ford, Doge Chrysler and more.
