replacement muffler $500?

[etlsport]

i walked into a big chain place to get the PV done.. asked the guy if they did exhaust work.. he says yea.. i tell him i need a muffler put up.. he says itll be a few days to get the part... i told him i already had my own muffler... he said they couldnt install any customer parts

I'll name names here... I had the local Monroe install the Flowmaster muffler and chrome tip that I bought separately and brought in to them.

($200 for install and replacing the stock piping to 2.5" piping from the flange after the d/s oxygen sensor all the way back)
