Exhaust system, spring loaded flange...
My truck developed an exhaust leak and was starting to get a little bit loud, so I took it to Mieneke mufflers, they put it up on the lift and found a leak from the spring loaded flange, and said that was what was causing the noise. They estimated the cost to fix it at $129 parts and labor and could do it right away, so I let them, now my truck is nice and quiet.
They also removed a counter weight that was on my exhast pipe. It looked like a solid 5 pound pop can with a brace to connect it to the pipe. I could never figure out what it was, but it's supposed to help remove vibration in the pipe. The mechanic said to just get rid of it because they just fall off and can become a dangerous projectile. So to prevent a problem I said to take it off. It practically fell in the mechanic's hand. No tools were needed to remove it. I'm glad it's gone now after seeing how easy it was to remove. It really can become a safety issue.
They said the rest of the system looked pretty good yet, so I was glad to get out of there without putting on a new muffler or catalytic converter.
