I have a 89 CBR 600F and have been wondering what exhausts systems are made today that might fit. Haven't really looked into it much but it's been in the back of my mind. Even just mufflers and not full exhaust systems that would fit snugly and not need any special fabrication. If you know any of the best, let me know. Thank you.
