I had my 355 Tubi silencer fitted yesterday morning... What a sound! As people say, there is a resonant boom from 1k-3k rpm, but this is a more exciting sound that a 355 normally makes in this range. Not unpleasant by any stretch, just very different. The sound above 3k is just stunning, and accompanied by the most wonderful crackles on a trailing throttle. Also, at 70-80mph, the car cruises quietly as before, and when cold, the sound is not resonant at all at tickover, in fact it is like standard so I can get the car out without winding the neighbours up... This is what the 355 was meant to sound like before pointy-bearded fools from Brussels got involved with their Db meters... I'd heartily recommend a Tubi to anyone who's considering having one fitted. I will post before and after video clips at some point, when I've found someone with a website who can host them for me? Thanks Manu and the guys at Verdis for sorting me out and being so accomodating. Robert.
