    I've recently fitted sportex rear box to my 1999 saxo 1.1but shut in the car the noise is deafening surely that's not normal ffs?.

    I wouldn't have thought so, is the clamp tight? Make sure you haven't got any leaks.

    A friend had a Sportex on his VTR and I could here it over my car with a supersprint/scorpion set up when I was driving my car in front, they are pretty loud.
