Default 454 exhaust brackets

(Stock LS5 standard trans)

Are the forward exhaust brackets a standard 2.5” or shaped specific for the bracket that holds both exhaust?

Not sure what you're really asking, but here is the AIM for the '72 LS-5. Perhaps re-ask using the item #s.

Thanks, it’s the # 1 and #2 brackets. I was just wonder if they are “off the shelf” brackets or a special shape for the bracket above?

I have had trouble with my own LS-5 in this regard. The hanger (#9) is a strange shape and the exhaust clamps just don't seem to fit it well. You can see in the illustration that the clamp is more like a strap than the off-the-shelf round-U clamp, which is what I'm using. I've not looked into it as it's a pretty low priority at the moment but am curious what others say on the matter.

I’ve done a bit of research but still not sure. I found this one at Corvette Central but it’s for a small block.

Exhaust bracket for LS5 is the 2.5 inch, Should be same from 68 BB to 73??
Small block is 2 inch
Check the judging manual as the exhaust clamps are different configuration between 71 and 72 and that applies to 72 Lt1 too
g

if you need one I may have one last one but have to check my filing cabinet

I don’t have access to a judging manual but thanks for the input. I don’t know 71 and 72 I different for the BB engine.
