thats the 2 boxes that i have removed and fitted an x pipe

You only need to remove the bigger box (the one with the dimples). Then weld 2 stainless steel pipes to the rear section.

Thank you very much for your reply , it’s going back in Monday to have what you suggested, it’s so bad I can’t even drive it currently

It will be perfect with the front silencer and 2 x rear silencers, without the bigger one!

If we all point our RR's in the same direction and accelerate at the same time can we turn back time?

The previous owner has already removed the very rear boxes, will that make a difference
