I have some pacemakers (ph4499) to fit to my AUII(dedicated factory gas), just wondering if i can simply take the factory headers off and bolt the pacies on?? because from what i can gather from different exhaust websites, in regards to intall there is no welding required and it will bolt onto the factory cat, is this true? Also if it is easy enough to install myself is there any guides as to how to install em??

Cheers

cool thanks for that....looks like ill have to get em intalled at an exhaust shop.
