Some exhaust screws broke on my old truck and the exhaust almost fell off. Instead of trying to replace screws by drilling in a small space, I bought these repair kits. Worked beautifully. Now the truck is quiet and people don't look around to see where all the noise is coming from. The kits fit perfectly, they are not that difficult to place even if you have to do both sides. I would recommend them to anyone who needs to have their exhaust system repaired.
