Had some money burning a hole in my pocket the other week so decided to treat the sapph to a new exhaust. It already had a Mongoose on it but it was about 12 years old and there was a small hole in the middle box which made it quite fumey in the car....anyway, i bought a brand new mongoose from Collins Performance... i fitted it and its louder than the one i took off!!!

I'm glad the fumes have stopped but i'm a bit annoyed that its louder than before, has anyone else experienced this? Do they quieten down after a while when they've 'carboned up'?
