Does anyone know what the diameter is of the exhaust pipes in a 2015 RX350? I'm especially interested in 3 locations - where the pipe meets the engine manifold, just before the muffler, and just after the muffler.

I ask because the exhaust system needs to be bonded to the chassis for a ham radio install, and the bonding kits come in different pipe sizes.

Thanks,
Juliean.
