Hi - has anybody got an old back exhaust box for a late P6BS (believe auto is the same) ? it does not matter what sort of condition the box is in providing the link pipe and flange are in reasonable condition for welding. Happy to pay postage. will consider a box in better condition if the price is right. I plan to graft on a slight;y louder can to liberate that famous V8 rumble - it would be good to hear from you if you can help.
