Thinking about a glasspack...

As long as he keeps the tail pipe it won't be very loud even with a piece a plain piece of pipe in there. Dodge's don't have a loud exhaust due to the size of the exhaust valves used. When I did the cat back on mine I fired it up after I cut it off at the cat, wish I hadn't spent the money on the cat back system cause it wasn't very loud right off the cat yet sounded great.

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.
