Does anyone know how much bigger the exhaust tips are on the M550i vs the 540i? I am upgrading to the M performance diffuser on my 540i with stock exhaust and want to leave the door open for future exhaust upgrades.

Many of the 540i aftermarket exhausts specify the M550i diffuser so I am considering getting the M550i M performance diffuser but just wondering if it will look strange when mated to the stock 540i exhaust.
