I bought an Eldo yesterday and would have asked you a question: How can you make the sound a bit more nurturing and louder? That’s already good if you are standing behind the car but I still find it quiet in itself. I wanted to inform myself. That’s the only thing I would change in the originality. And the H character is not affected by it if I just do that. My Coupe has a double exhaust system as it was delivered in 1970. I am looking forward to he takes a picture in. mfg Marco Jansen
