I'm assuming this will work with G23 (convertible)?

Would not without modification. The vert's have additional underside bracing that interferes with the enlarged pipe routing.

Would take some fabrication but a competent muffler shop I wouldnt think would have too much of an issue. What exactly it would entail I could not say but at worst it would be cutting off the inlet pipes altogether and routing smaller pipe instead that 2-2.5'. With how much growth happens in the pipe when heated I just don't see the bigger pipe working with the existing bracing despite any modfications without some rubbing either when the system is hot or cold.

Does this apply to G26 as well or will it bolt on normally like the G20 & G22?

Applies to the G26 as well. Utilizes the same additional underside braces.

Such a good design utilizing the stock valve system. But how can you sell a straight tip exhaust when the stock diffuser is tapered the tips look so out of place. Amerritx, FI exhaust all have this figured out don't see why you guys can't

Couldn't say for sure one way or another as it's never been fit on the hybrid but it appears unlikely. From comparing the factory ETK's, the factory exhausts themselves have different part numbers and appear to have different cut points, hanger locations and pipe sizes (330e pipe is substantially smaller) so even if it would physically fit, at minimum, there would be some adaptation needed on the pipe side.

Will this fit my 2024 LCI 330i? Also, are the valves controlled by a remote control or is it controlled by the car’s original actuator by changing drive mode (like the stock muffler)?

Yes it would fit the LCI. Valve behavior is the same as OEM as the factory actuator and control (factory ECU/programming) is retained. For full control of the valve you would need to purchase the remote valve controller that Dinan and a few other entities offer.
