I have Thunderbike exhaust and it gives a nice sound and won't make you deaf, cars will hear you when you ride next to them. Try looking at the pipes at www.Thunderbike co. nz I believe there's a youtube of those pipes with the bike running. Good luck.So I'm a fan of the look of the stock exhaust and would like to put some tors on but apparently they are made of unobtainium. So what other exhaust is there that keeps the stock look. Preferably one that wont make me deaf
