Well had my new exhaust system done! and its made a fair bit of difference instead of it pulling only to 4.5k it has opened up another 500 revs in the range pulls alot nicer... a
as a bonus the guy who mapped it is going to add a touch more boost and fuel on the map to match the exhaust for FREE!!
will get pics of the exhaust but for the time being here is a video
Audi A4 2.5TDi exhaust - YouTube
also does any one know why at 2.2k the exhaust gets alot louder like it opens a valve up or the turbo comes on full chat? hmmm you cant tell in the video but its a noticiable difference in noise, it goes alot deeper at 2.2k
will chuck some pics up shortly
