I just bought a 1983 1100 e ,I really like that howl that the motor can produce but I´m unsure of my options I know a 4into 1 header would be great but what is the best sound/brand for the buck ? and if I do go to a header do I I need to change jets and re- tune the carbs ? I am really looking for a agressive sound and I dont mind loud as long as it sounds great. Any thoughts would be great Thanx Your niebour up in Canada
