2005 megane cc powerflow exhaust questions-- sorted now

[lukas430000]

Hi all.
This is my first ever post on this forum. Firstly to introduce. My name is Luk and currently driving a 55 plate megane CC(pics to follow still have to make a introduction thread) Car is in gold and pre facelift. Wee engine 1.6 is enough to pull it. Clutch bites quite high but in good condition. And my qestion is as follows. Done few mods to it like led interior lighting and auto dim mirror. I have inherited a powerflow backbox from my mate. I would love to fit it to my Meg but I have no clue how to. As it's CC the floorpan in a boot is plastic and oem exhaust just doesn't do anything. I would love to see others with fitted aftermarket backboxes. But not from behind as I know how it would look. Just looking for fittment instructions as such. Maybe pics or some advice...
Sorry for that long post. Just wanted to explain and introduce myself.
