To save starting a new thread, I've got two questions. I've searched my arse off, but haven't come across definite answers, or they are outdated...

With my MY99, will it need a tune with a TBE. Some people say no, others say yes...I obviously don't wanna fuck my engine, but if it requires a tune, I probably wouldn't bother with a TBE and just get a cat back. I won't be doing any other mods in a long long time.

Also, I've read about the Varex mufflers. They sound like a good idea, but I understand they are illegal. Is it the sort of thing that gets a yellow sticket/big fine easy, or do you have to be a prick to get a copper to bother checking for it?
