I also just bought a set of Chevy605's and haven't received them yet. I have a new 07 TBA and don't like the look of the tapered pipes. The ones I bought from Chevy605 are the long, slash-cut ones from a speedmaster and I think they are much nicer looking.

I was thinking about keeping the stock pipes, but I don't really have a use for them and like I said, I don't like their look, so I'll take him up on the $75 core charge and return them to him.
