Pipes come from the factory, I've got a few here but they have a price tag of $28,900, though you get to pick the color of the wrapper

You should have Nittos on the 17" wheels. Something else is up. Take a good look at it from the bottom side. Things can loosen, that's part of the game if you drive 'em.

We chased a similar vibration on a car here with the 17" Team 3 Wheels, after 3 rebalancings and the replacement of the front wheel hubs we were left with a vibration at 80mph exactly... off at 79mph and off at 81mph. Left it as either the Nittos or the Team 3 Wheels themselves. Prior to all the work the vibration was 60mph to 85mph.
