Hi, just after a quick bit of info. After trawling up and down the search function on here, i'm still stuck as to which exhaust to buy to replace the standard exhaust system on my 07 A3 S Line TDi 170? I've found that the TDi 140 has a replacement exhaust but all I can find on such as Miltek ect.. is for the 140. Also is it any use having the DPF removed and remapped out, any advantages? I'm a little reluctant to have to car remapped to silly bhp because i've heard about turbo's not taking it ect.. Any ideas peeps?
