Hey lads & ladies,
Just wondering if i have to put my center cat on my b4 for the nct or will it pass the emissions with the primary cat on its own :ponder2:
know it prob a silly question be jut me being lazy :lol:
 
It will pass the NCT if the Primary cat is still in place. Plenty of lads have passed with the primary cat only :thumbsup:
 
As above it should pass no problen once you have original downpipe still in place.

Only put my impreza through the Nct last mont at it passed with centre cat out :thumbsup:
