As the title says. What is the recommended size for an x pipe. I plan to get rid of secondary cats and resonator.

My understanding is that some of the '03 E55's may have smaller plumbing (60mm). Any reason you can't slide under your car and measure what your car has? Don't have your X-pipe be of smaller tubing than your existing tubing.
