2003 Clio 172
I had my pro speed non resonated cat back exhaust fitted about a week ago, and at first was surprised that it was quieter than I expected. It had a nice raspy tone, but was not overly loud. I've since gone through a tank of v power, so just under 250 miles, and it's definitely gotten louder. I actually thought it may have been blowing, but it just seems like the volume has gone up. I actually prefer it now its louder, but is this a common thing? I've done a bit of a search am seeing conflicting information. Some people say exhausts need to bed in and they get louder, other people say they quieten down ?
