what have you go in the place of the CAT at the min? Get one made up from somwhere? I usually avoid powerflow but its only going to be a small length so should be ok.
Mines got a decat and its fecking deep

Not just a straight though pipe.

My first decat was a Janspeed silenced section, but eventually the baffles inside came loose.
The more "boxes" you have on your system, the more you've got to fail and rattle.
