@wickedchameleon I purchased the bike with the TB exhaust already installed, so I can't speak for performance difference. But everyone else I spoke with says it makes a noticeable difference in power. If nothing else, in terms of looks and sound alone it's worth it compared to stock can.
Iv got a 04 model 05 year Daytona and I have pipeworx race pipe on I ay it sounds much more meaty am comes its detachable moderator, increase hp, not noticeable tbf, and looks amazing
