My jag xk 4.2 2007 is to quiet - can i remove the 2 blocked ports on the rear silencer and have quad pipes out the rear as per xkr - help

 

as i understand the xk and xkr have two different set-ups .the xk has a tim valve but the xkr has a active valve which needs a vacuum pump to close it ,so if you put a xkr rear box on a xk the valves would be open all the time aka more noise

 

Thanks for reply but can i remove the tim valves on my existing xk
silencer and add the two pipes to give me a quad outlet look like the xkr will it be to noisy - regards
