Mufflers repair service near Aquadale, NC

I recently had our car's muffler upfitted due to the fact that the dealership told us that present muffler's intake was not allowing enough exhaust to pass through. This Meineke shop charged me $650. to update the muffler. I have had since then trouble with the muffler now vibrating and making a clunking noise and brought it to Midas muffler to check out. Midas says that Meineke installed too long a pipe causing the noise. Midas also said they could have replaced with a brand new muffler for less than $650.? Midas only charged me $45.00 to shorten the pipe where it needed to be as well as repair a dangling cadalytic converter heat shield. Meineke not only ripped me off, they did not install the muffler correctly! This review is not meant for all Meineke Muffler shops, just the one located 6447-A East Independence Blvd.!
