Diesel though...
I'd already read you thread....and yeh looks and sounds good...but its not a diesel!!
I did it to an Allraod 2.5 v6 tdi and the result was believe it or not it sounded exactly the same.....I was gob smacked given the size of the rear box's... There are performace rear box's on web and flebay for the 4.2 tdi that boast a berble....but thought full delete would be better...just need to know if anyone dune it without replacing the full system. Thanks Rossy

Turbo's, cats and DPF's do a lot of silencing so I think it will not change all that much if you remove backbox. I am not sure if exhaust is in one piece or several sections. If its several sections you can just remove rear part for testing purposes to see how it sounds without it?

Link inc.
Was looking at these:-
http://www.ebay.co.uk/itm/Sport-Perf...item256d6a88ee Or Possibly seeing if these could be modified... http://www.ebay.co.uk/itm/GENUINE-NO...item3ccd70e58f But thought given the above (and not sure if mine has the DPFs 2005 model?) could I go my local stainless fabricator and just get them cut off and strieght through pipe to a set of nice Twin (quad) tails.... But as the boxes above state they give a berble did not want to get rid of the rear boxes and end up with a spitfire sound!! The rear boxes as standard would have to be cut off, otherwise, yeh I'd have removed for a sound test. Also if it does not make a differance why the hell did Audi fit such HUGE rear silencers????? 1, they are real heavy and 2 restrictive!!!????

ok ive done this twice
1st i did my 3.0 tdi A6 just had POWERFLOW remove the back silencers and replace with stainless pipe and nice tail pipes (it was a tiny bit louder) 2nd i went to powerflow with my 2008 3.0 tdi A8 sport i told them i wanted it louder so,, they made a full system cat-back with larger pipe than the standard audi pipes then added huge tail pipes ........... it sounded amazing !! not too loud either,,just right,, So i think a V8 diesel will sound amazing if you do the same.... and only around £400 made to measure there and then while you wait lifetime warranty too
