On some y7 and y8 downpipe bracket, y7 is one side and y8 the other side, because they are different oem design, y7 have built in cat and small gay downpipe, y8 have 4-2-1 manifold + cat at the end. I bought y8 header, and weld bracket the others side, but bold pattern on head and path for header is the same :)

good luck !

yeah, but it depend it comes from who. I got pace shitsetter, and dont have model for y7, I took y8 one, and downpipe end bracket didn't fit, I just modified itm, and work well since 3 years...

y8 oil pan is lower than the y7... everyone sure that the downpipe on the y7 manifold will still tuck under the y8 oil pan?
Ha ha, yeah. The Y7 downpipe is tiny, and the y8 has two runners. It will fit.
