Not meaning to hijack a thread, my 04 newage has been completly decated, up pipe, down pipe and centre section, question is can i have a 100 cell sports cat choped into the system somewhere, probs roundabout the down pipe type area and what sort of effects will it have on my cars performance, i asume i would need a remap aswell, reason im asking is due to my job driving trucks i'm noticing more and more vosa emmisions test vehicles out and about and its only a matter of time before i get pulled over by one, im currently running a full magnex system which magnex no longer make.
