Hi, new here and new to the single cylinder machine....just bought an XBR500 and would like to change the exhaust back to the original twins eventually, currently fited with a micron 2-1. Had a quote for the downpipes and norton commando peashooters were suggested to go on....but wondered if anyone could give me any more suggestions just out of curiosity...not looking for anything overly loud....just a good thumper sound. Cheers, Dave.
