That sound is good while you are driving up the street, but get out on a day long drive and the drone will drive you nuts.

I too recommend a flowmaster or any other "turbo" style muffler over a glasspack. They offer better flow characteristics for performance and mileage than a glasspack. I much prefer the deep throaty sound (classy) to the cheap harsh noise of a glasspack, straightpipe, or rice grinder tin can.

If you dont have the tools to do the job, yes, you should take it in. The muffler you have is clamped on, but after this long, the pipe is crimped and almost rusted together. They will likely sawsall it off, and insert a short replacement piece of pipe, depending on how long the new muffler is.
