Sorry for the delay Manesh.
I have a full stainless exhaust with a loud DTM backbox. its abit dirty in that pic :-[
If your after the extra breathing for your engine then i would get a full system.
The noise can get very annoying on motorways but i reccomend the full system to the back box
I only travel to my sisters house in lesta so you probably know more garages than me mate
What one are you looking to get? Im thinking of changing mine to a letterbox DTM once i have the extra funds.
