hey all i am going to be buying a Xpipe sometime soon here and wanted to know what your thoughts are on if i should go with the offroad or the Cat version.... i do plan on adding a supercharger soon also.... and i know that SC/Turbo 4bangers tend to preform better with out Cats is the 4.6 the same way?
also what are some of the pros/cons of either setup aside from inspection and a sniffer
