The new flowtech raptor vs others....

I had my car worked up recently and the shop was supposed to install flowmaster 50's, instead they installed flowtech raptor's...... The excuse was they couldn't fit them in the 71's rear.... fine by me. But they still charged me 400$ for an exhaust sytem that uses 20$ mufflers...... Are the raptors any good? What can i expect if i remove and replace them with something else. Also... while i'm at it, anyone heard of the dart thunder head? I here its a new head, supposebly the one they installed, how does it compare to the GM vortec heads..., tks.

Can't help you with the head question, but I put Flowmaster Delta Flow 50's on my CE and love them. You can go here and maybe get some infoo
