If you have a 2 1/2" catback and you add a 2 1/2" midpipe with highflows cats, you are going to gain some good power in my opinion.
I was happy with the mild power gain. Felt about the same as when I put on my underdrives. Nothing crazy, but it was noticable.
If you don't have a 2 1/2" catback, I think the gains would be very minimal though.
