Will Doug's Headers Fit or What???

just bought a set from Summit, ordered late Wed and were here FRi. Looked on ebay and there was a buy it now for 486 plus shipping with a total for $502. Summit matched that and sold me a full exhaust, 2 1/2 in mandrel bent out the back with mufflers for $209. Headers are ceramic D453 without the R. Total to my door for whole exhaust $708. In my opinion can't beat Summit, Joe
