Not sure what to do. I'm most likely going to be getting another exhaust, and going from 2.25" to 2.5" pipe, among some other issues but I'm not sure what muffler to use.

I want a nice, deep tone. I was thinking of using a Flowmaster 40 series or Super 40 or Super 10. With that, would it be a good idea to do the glasspack as a resonator trick, as long as it's the same inlet and outlet sizes, so I don't get any buzz?
