Yes, you can do it, but you can afford to make mistakes like trying to lay a perfect weld with extremely restricted access or without removing the exhaust system correctly. It takes only half an hour for anyone with knowledge to remove the exhaust. Follow these tips to save yourself from further complications. 1. Use proper gear to protect yourself from toxic fumes coming from galvanized metals. 2. Use a high-quality heat shield (preferably a sturdy metal sheet) to protect various components. 3. Tack your metals together properly while removing the exhaust. 4. Use the right filler for stainless steel exhaust pipes. 5. Use heat-resistant paint to enhance the rust protection on steel pipes that use an aluminum coating.
