I bought a brand new set of MIVVs online. Delivered quick enough.

Issue: the fooking things are asymmetrical! One sits higher than the other and leans inward. I've stuffed around with mounting for hours - can't fix it. So I'll be spending an extra $200 to have them professionally modified but an exhaust specialist.

To say I'm jacked off is an understatement. I paid over $1000 Australian for these, after considering Yoshis again. The cans themselves are beautifully made, it's the Y piece that is crap.

So fair warning - if you buy MIVV's, you may very well get a shit set like I did.
