Here's what some people do.
The Sato inlet is 54mm's. There are adapters made that will accept a midpipe that has a 60mm sleeve, and a couple other sizes. You're not limited to Sato mids. I believe Yosh mids will work with an adapter, and certainly some other brands too. Find some good ti lowmount mids, verify measurements and get the adapters.
Maybe someone will chime in with a few more brand name options for midpipes, I only mentioned Yosh (which are stainless, not ti ) because someone here did that recently.
