I wasn't sure were to post this so i put it up here. But i have a 1997 chevy pickup truck that is used as a plow tuck and utilty truck for our property management busness. And i started it up and then walked around back and noticed theres almost no exhaust comming out from the back and you can hear it leaking out from were the passanger and driver are placed. I could not see any holes or anything maybe they're ontop. The truck has a single to dual exhaust so theres one muffler but two ends at the back of the truck the muffler is not even rusted but everything else is. And its really loud inside the truck. I was wondering if i should pull the exhaust off and find the leak and patch it wtih either just a weld or a little piece of sheet metal welded over it depending on the size of it. Or if i could use one of those wide metal band clamps and just put that over it. Also i'm not sure about this since i've never done exhaust work but i was thinking also that maybe it could be a seal or gasket from the header to the exhaust because thats right in the area that i can hear it comming out of. Let me know any of your opinions on how i should go about fixing this one.
