I really like the full TI single side Expreme they just came out with for the BRZ/FRS. I bet it would be so much lighter and look a lot like the NISMO Z-RC packaged cars. For hard core track it leaves room for diff/trans coolers too. There's a few Youtube vids of 370's claiming to have this exhaust, I'm guessing they modified the Z33 version to fit because one of them looks like it hangs out way to far to have been made by Tomei.
