I have a '99 F355 GTS, and am looking for a more exciting exhaust sound than stock. After reading many good comments on this site, and much deliberation I have ordered a Tubi silencer (not the full de-cat at this point) to be fitted in a few weeks. Just for my reassurance that I'm doing the right thing; Probably a silly question, but will it make a really noticeable difference to the way the car sounds? Can anyone describe the sound for me, from inside the car and out, in the different rev ranges? I look forward to some descriptive prose! I've heard soundfiles of a de-catted system, but not of a silencer only. I'd really appreciate your comments. Robert.
