Foamy urine is characteristic of having an excessive amount of protein in the urine. Proteinuria may be detected in a urinalysis. In these cases, experts recommend reducing the intake of protein supplements or excess amounts of high-protein foods. Medical consultation is advised for appropriate diagnosis and treatment.
Minor muffler repairs (such as welding a loose but still functioning muffler back in place or fixing broken clamps) can cost $30-$500 or more, depending on the specific work done and local labor rates. Most report finding the best repair prices at small, local muffler shops.
It depends on the repair involved, whether you want factory components or are OK with the shop just welding something up, and how much of the pipe is damaged. To weld a new generic muffler on an old car is generally about $100-$150. To replace the exhaust system due to damage on a sports car or imported luxury car could be over $1000 (mostly in parts, the labor part of that is actually fairly easy).
