Diggy98 Posted December 16, 2017 Share Posted December 16, 2017 Hi, I was thinking about installig some TFSI mufflers on my 2.0 TDI as I would like it to sound just a little louder, but not too much (which I'm afraid deleting them completely will do). Any ideas? Has somebody done this? Quote Link to comment Share on other sites More sharing options...
niedzial1983 Posted December 16, 2017 Share Posted December 16, 2017 Unlikley. Just do a back box delete Quote Link to comment Share on other sites More sharing options...
Simon H Posted December 25, 2017 Share Posted December 25, 2017 I've done the delete on my OCTAVIA diesel. It has helped reduce back pressure and the turbo spools up quicker. Looking to do the same on my A4 convertible but it has 2 rear boxes so will be about £200. Will have to wait till after the new year.

Steve Q Posted December 26, 2017 Share Posted December 26, 2017 I don't think the petrol ones will change it much. I'm with the others on this and a backbox delete, it won't make it too loud either. IV found this video on YouTube which has a a4 diesel with the backbox delete: Hope it's useful :) Cheers, and merry Christmas :) Steve 1 Quote Link to comment Share on other sites More sharing options...
