Here is the reply from Steve, if anyone knows the answer to his question let me know.
I do not have access to the vehicle … but when I see photos of the Ti, I notice it has only two exhaust tips, whereas the QF has four. The QF has the exhaust bypass valves, hence the reason for the four exhaust tips. As the Ti has only two tips, my first reaction is that it does not have exhaust bypass valves … but that is not necessarily 100% as it is possible it still has exhaust bypass valves … just not in the exact configuration as the QF.
When you get under the car and look up at the exhaust system, are you able to determine if there is a vacuum actuated exhaust bypass valve somewhere up there. Perhaps immediately forward of the silencer although it could be built-in to the silencer. There would be a vacuum line up there as well as the system uses vacuum to open/close the bypass valves.
If the Ti has bypass valves, then the answer is yes … the controller should work. If the car does not have they bypass valves, then, unfortunately, no.
