Will the HKS downpipe be OK to replace the standard cat or does it need to be mated to a full HKS system??

my reason for asking is i have been offered one at a good price, i have got a magnex system on there and the standard front cat (decat center).

any ideas??

 

Yes it will fit.. but the HKS blocks off the wastegate like the standard one so you will get better results with an open neck downpipe such as Scoobysport, Hayward & Scott.. or a twindump like Magnex etc..
