Overrun Popping issue.. Or lack of?

Tue May 28, 2013 6:35 pm

Would a terrible back box ie stupid jap can or non standard centre section affect the overrun cackle and popping?

I'm noticing a lack of it just now although the car isn't up to my standard just yet. Manifold looks standard. Centre section also looks standard but possible weld near the cat. Back box is stupid. New back to be fitted this week.

I know a few never popped and banged from factory. I know it came from the map but would anything else affect it?
