I've recently fitted the CSS backbox to my '15 PP DSG.
Wow, is all I can say. This is the way the car should have come from factory, the sound, the bigger tips, and the backfires.
I was able to cut the original back box off without removing the whole centre section. Unbolt the rear cross brace and the flexi on the down pipe gives you enough wiggle room to drop the back of the exhaust onto some axle stands.
There is a slight increase in cabin drone but nothing major. I still have no qualms about putting my new born into the car so it is definitely not intrusive.
Under load however it is a bit louder, loud enough to turn heads. At WOT it sounds amazing. A bit more volume than the factory back box which is welcomed.
And then the pops, the pops! The back fires out of it are ridiculous. So much so that I try not to shift gear when overtaking a car so that I don't scare the bejaysus out of them.
I picked up the backbox and clamp from a VW dealership here in Dublin, Ireland for €430. I don't where the dealer quoted figures of £595 are coming from....
