Hooker,doug's,TTI?

Here is my set that arrived today, DD-9 plain. Once I get my motor back together, I'll get them installed and after I run them for a bit I'll send them off to be ceramic coated. I'm glad I went to Summit and ordered thru them. It took a while but worth the wait to get them. If they fit like everyone states they will I'll be happy and the price was 1/2 of Doug's and TTI's!
