Great write up!

Are you planning on removing the primary cats and a tune of some sort?

How would that impact upon the noise levels? Ie would you say there is room to manouvre without sounding like a cheap loud exhaust

I'm thinking as an alternative, to remove the pre cats and leave the back box OEM
