Boxer Owners - Who Has Cats?

As I indicated in a post in the techie section, I am coverting my car back to original form and dispensing with all the US federalization gimmicktry that was put on twenty years ago. I plan to change the plates to classic status to avoid emmissions testing altogether, so I am not concerned with registering the car legally in my state (PA). If I ever happen to resell this car, however, potential buyers might have an issue since other states may not be as generous with emissions exemptions. What do you non-cat Boxer owners do and have you had similar thoughts about this? I have heard that a properly tuned BBi will pass most state's emission tests sans cats anyway, so the point might well be moot.

Thanks

 

Thanks. Injected cars can be "tuned" to pass most reasonable tests as well for tests designed for cars of that vintage. I have an orginal four-can exhaust system which I was going to put on, but it has no provision for test pipes or cats, so the answer might be to go with an aftermarket exhaust that has a space made for cats or test pipes. This way, at least they can be added if/when necessary.

Anyone else care to opine on the setup of their Boxer and if there have been issues with emissions testing?
