ok this might sound like a daft question but just befor christmas i did an oil change. and while the car was in the air i had a good look over her. their is a decat box fitted with a silencer and a port for a after cat sensor. their is no sensor fitted their. it has a plug in it. and in close prox to this their is a chopped wire. this was like this when i got the car. is this a normal modification, or could this be the reason why my R has a flat spot between 5000 rpm and 5500 rpm
