Much nicer isolators. These are really stiff and are absolutely needed to hold a 3" exhaust in place. It will hit the heatshield constantly otherwise, as the stock isolators are made of soft cheese.
Arrived well packaged, five minute fit, start by jacking up your car… spray to lubricate and slide off the old ones. Pop on the new ones. Far less wobble on exhaust now. Job done.
Worth replacing these whether you buy the Mountune exhaust or not. Limits the movement of the exhaust system, which is quite excessive with the standard Ford isolators.
