No one can say 100% that your Cobra will always be able to be registered...

In saying that I seriously doubt that you will ever have a problem with continuing to register that vehicle. As long as you don't let the registration lapse you will be fine. Same story with transferring registration to a new owner, will be no problem at all. Historically QLD Transport have not made any changes retrospectively, that would also apply Aus wide.

So I wouldn't worry.

Without any chassis modifications you can always run the exhausts out the side just in front of the footwells, they will exit just through the rear edge of the front guards(raised section). Doesn't look too bad, just keep the primary size down and keep them tight. Pipes line up with the edge of the guard, so no problems with wheel/tyre clearance.

With the seat warmers, you really believe in variety with your questions, don't you?
