If you're not in a big hurry ....
I'll have a set of ATR's with Cross-Over in a few weeks. I bought a set of GN1's, and hope to get them back from the coater today, and installed by Mid-May. I'm taking off a set of ATR's, and only because the brace on the passenger side that stabilizes the header extension where the turbo bolts on broke again. So I plan to take the ATR's off, attach a stronger brace, and put them up for sale. Sorry I don't have any pix of them handy at the moment. I was thinking $350 shipped after I get them repaired. Let me know if you're interested.
Sincerely,
John A, turbohh
