Get MC28 specific pipes. It's gets too complicated else! TYGA, HARC Pro and Jha all make/made pipes that fit both models, but only TYGA are still in production.
If you buy used pipes, get ones specifically for the '28.
Are you sure the cards that came with your bike are HRC cards? Has the wiring already been adapted to use them? If a seller is unscrupulous enough to sell an MC28 quoting it as having 70~72hp, then I don't see them having any problem re-badging a stock card as an HRC one either!
