Yozza Sport Exhaust (Help please??)

[chris197sport]

Just fitted a Yozza sport exhaust on my 197 today including De-cat.

Love the exhaust however every now and then the car stutters around 2600rpm. Is this normal when having changed exhaust or after puting on the de-cat?
Will it help reseting the ecu?
Do i need to get it Re-mapped>? (was going to get done anyay)

Any advice would be apreciated...
