hi!
No, I haven't removed the pipes.. but what you'd need to do is remove your bumper in order to access the resonator to remove all the remaining pipings.. i'd take pictures of it when I do it the next time. I don't think there's any other way because of the screws mounted.
and you're right.. without removing the stock resonator, I don't think it's possible to add another pipe.
.. and I agree on the radiator... would have been BEST to have RAM Air effect that way.
Cheers,
