I ordered my Greddy EVO and it should be coming soon, but I found a picture on the internet and it showed 2 "hangers"(its circled on the picture) on the first pipe (right after the cat converter) so i looked on my car to put WD-40 and i only saw 1 "hanger" on my car

...is that normal? do i only use one of the hanger on the pipe? i have a 99 ex
