Thanks guys. I'm not necessarily looking for a certain sound. I'm more interested in squeezing power out of this thing. I figured that 2.5" pipe running into 2.25" pipe isn't doing my car any favors. And there is a small chance I will be doing some more power adders this winter. I was just wondering if anybody had experience with testing pipe sizes to see what the difference really is. If it's 5 HP I'll pass but if there's say, 20 or so to be found I'd go for the full cat back.
