Ok, so I don't do massive mileage in my baby. Now 19 months old and covered around 8,000 miles. What's really surprised me is how much the exhaust sounds have improved over time. I realise that this is no V6 but the sound coming from my pipes now is absolutely tremendous. Others have also commented on it........I have an addiction to making a few pops when I drive through the barrier at work as it echoes quite nicely there. And as for tunnels.......brilliant. Am I imagining this or is it a case that as parts wear in and maybe the changes with the interior exhaust coating causes this effect?
