Hi there Hamz, I ended up with a xforce hiflow ss cat, which goes to the stock mid muffler / resonator, which goes to 2.5" Stainless steel pipe (same size as factory, but shiny), which then goes to the xforce varex 2.5" twin 3" tip.
In regards to sound... shes awesome, must admit, when the varex in closed, she sounds quieter than stock, and when shes open, shes roars pretty loud, but not annoying. I decided to keep the mid muffler / resonator to keep that nice deep low note the sportivo has. When in LIFT, its CRAZY! hehe
PS. I would definately recommend. PPS. when the varex is closed, drives like the how the car was before, when its open, its a different car :P
Let me know how you go...
Steve!
