They also told me because I modified my car, this would void my warranty.
Pretty sure I won't be getting my cars serviced from that dealer again, given that the extent of my mods is an intake and exhaust.
Also, I hate to be "that guy" but I kinda doubt this conclusion, because I can't quite see how an exhaust leak would only happen at 75kph and 120kph, and have a tendency to be louder/detectable through the steering wheel only when I turn to the right hand side.
Anyone have experience with this sort of thing who can chime in and let me know if I should bring it to another shop for a second opinion?
Thanks!

An exhaust leak causes noise, not vibration. If a vibration were caused by resonance, it would be at around the same RPM in every gear, causing it to happen at multiple speeds.
Go to another dealer or shop that is more willing to help.
