That or plunk down all $600 or so for a completely new system. Input on this? Will-do on contacting Greddy...thanks guys.

you're welcome!
universal mufflers always require custom welding, since 99% of the time its just the muffler itself. Good job looking for a good welder, most cheapo muffler shops just bird poop the welds enough to make them seal. if u've ever looked inside a crappy exahust weld, you can see the weld flash on the inside of the piping, interfering with a good chunk of the exhaust flow.
i see from your sig that you're supercharged, so maybe you're due for a 3" system anyway. you'll see some nice gains, that is, unless the SP2 system on your car was already the forced induction version with bigger piping
