Just looking at the different exhaust options for my EA82T RX.

 

Let me know what you have and a pic would be nice also.

TD05 16G

2.5 inch turbo back

dynomax 2.5 highflow (not straight through)

2.5" with Hi-Flow cat as the only restriction.

I do too have one like Skip's. But it was on my GL-10, but, it's just sitting around now, as the GL-10 went to the crusher .

 

Mine's 2.25" all the way back to a glasspack. I had a flowmaster on it, it sounded ok.

This is what I had for my RX. Never installed it, sold it to Subaru_Styles after I sold my RX. It was custom made by an old member who no longer frequents here. Sure wish I had a chance to see what it could do:
