Here is the link for the specs on the Dynomax Super Turbo muffler. The part number is 17747 (2 1/4" center inlet/offset outlet). I'm not sure what the muffler cost, I had mine done at a local muffler shop (not a retail chain) for about $100 installed. They let me try the Magnaflow, Flowmaster and the Dynomax each for a week and didn't charge any extra to do this.
