Anyone fitted a switchable Exhaust to their 350?

[350zDad]

Hi, My son has a 350z and absolutley loves it. His exhaust was broken where it goes into the back box and it sounded amazing.

Unfortunatley he's had to have a standard exhaust fitted as he didnt have time to check around for a performance one as he needed an MOT.

My car has a switchable exhaust from the manufacturer and he asked if I could do something similar for his.

I'm aware of the aftermarket switchable kits that vent under the car but not a lover of the idea of this because of exhaust gasses.

So just wondering if any of you guys have created a clever solution to this? I do have access to a really good welder.
