rear audi exhaust diffuser
this is my first posting on here, i am in the process of purchasing an a4 s line 140 version tomorrow. I have noticed that the 140 version exhaust has twin pipes only on the one side. Would i be able to change the rear diffuser to a twin pipe 170 version without any mods. And would the exhaust system on the 170 fit straight onto mine. im hoping that because both cars are more or less identical except for the rear diffuser which i believe can be clipped off, it will be possible without any modification.
Did you ever go through with this?
