The Hyper Titanium has the 4" piping, and it is also from the DP back. I.E. you will have no more cat. The regular Hyper is only 3" piping with a 5" tip.

Depends on what kind of performance you are looking for....

If all you want is a more performance than stock, you can use a hi-flo cat which will give you very good power gain. If you want more performance, a mid-pipe will add to that, and increasing the diameter will increase it even more. However, I'm not sure of the power gain going from 3 to 4 inches though..
