57 plate 3.0 Tdi exhaust pipes
 

Hello everyone
I have a 57 plate 3.0 Tdi A8 quattro sport,as you will know it has the downward facing tail pipes on it,is there anyway I can fit straight out tips
I have seen A8 parts have a pair of petrol A8 tips for sale is it as easy as grinding off spot welds on my tips and fitting the straight out tips or is there more to this involved
Cheers Andy
