yeah, i stumbled across it from a wrecked cobalt on nwgmtuners.com.
i had to drive 120 miles to pick it up. but it was worth it!
then i found an angled tip on cssn for 45. so i got my 600 dollar exhaust for 245.
so its possible. i knew i wanted the gmpp from the get go, but waited.
got LUCKY for sure.
hope you can too!
