I have a MY01/02 Impreza WRX with a PPP, and was wondering is it worth getting a ScoobySport Downpipe and De-Cat Centre Section. But the ScoobySport De-Cat Centre Section, look the same, does anybody know if they're different?? And what will buying these 2 ScoobySport products do if terms of Bhp and torque, as I have 257bhp and 261lb/ft of torque.
