Alarm Recommendations for 197 Cup

The current alarm system on the 197 is good but i want something that has sensors when someone goes near and makes a noise and also a siren that is loud as hell. Any of you guys changed your current standard alarms, if yes then please tell me what alarms you have and if they are really good.

Cheers Sony
 
not sure if many people either mate. The standard alarma on them are pretty good. they have a very high rating (check the thatcham site). From the outside theyre pretty quiet. Sit inside though and its ****ing painfull lol!
 
Dont think any are worth it tbh have a look what difference it makes on insurance mate
