I got my camaro back from the shop after installing my pacesetter headers and full cat back set up. It seems to have a leak, and from what I see it seems to be from the EGR. I did a search and found no definitive answer how to fix it. I don't want to block it off, and the only thing I can think of is to get a small clamp to hold the non-bolted side down.
Has anyone come up with a good fix that doesn't involve deleting the EGR?
JB Weld. It's about the only solution other than a sim. You'll have to coat the thing with it. It does work, mine's been solidly sealed with it for months.
Copper RTV works well, mine is blocked off and I used it around the edges, no leaks.

X3 on taking it back to the shop. EGRs are very tricky to seal with pacesetters you could try to double gasket it. FWIW i blocked mine off and sealed it with red high temp gasket maker. you don't need an EGR simulator but you MUST run premium fuel if deleting the EGR
copper rtv works fine, unbolt it, place a bead around it and put it back on.
keep checking BOTH the header bolts AND the y-pipe bolts. they will loosen up atfer a few heat cycles.
if you do go ahead and block it off, you dont need to run premium fuel. you'll be polluting the air more if you dont, but you have HAVE to run premium gas. the EGR its self is just to decrease the amount of "NOX" coming out the tail pipe. nox is created from high cylinder temps (cant remember exact temp)

you can also take the entire egr assebly off, put the egr tube on then put the rest of the egr assembly back on..i did this and mine doesnt leak, i didnt use any thing but the supplied hardware... the problem isnt the pacesetters its the old tube has been hooked up in one position to the old manifold so its hard to bend and flex to connect to the pacesetters..thats why i took the whole thing off and attached the tube first

i dumped the egr and my car runs fine for years on 87

my point exactly.
myself, like stevethepirate, probally bent the tube during header installation. i bent the hell out of mine too, and tryed to seal it but in the end i just blocked it off. i too run 87 octane and have ZERO issues.

You monitor knock retard while your at part throttle cruise? The issue with just leaving the EGR unhooked and not having it tuned out is the PCM adds timing while at part throttle cruise for better MPG. Without the EGR working correctly the PCM pulls that timing because it spark knocks and your MPG drops up to 3 MPG. If you don't have both ends of the EGR sealed, You now have a vacuum leak when the valve opens, letting in unfiltered unmetered air. While the O2 sensors compensate for this, the PCM keeps adding the same percentage of fuel when you go WOT due to the fuel trims not being at zero.

1. my EGR is sealed, on both intake and the exhuast side. i have NO vaccum leak.
2. i got 37.8 MPG all highway on my trip from N.E. PA to cleavland. right under 70mph cruise controll the whole time.
i do agree about the mileage thing, but its probally more like .5 - 1 mpg loss at best. i still get 28ish mixed city/highway more city and highway
with no vaccum leaks i would think the pcm would componsate, later model ls1's went with a slightly smaller cam and did away with the egr.
personally, i dont care that my egr is off. its been done before and myself and others have had no isssues with it.

^ My EGR is sealed also and no vacuum leaks, I also think I didn't lose MPH(if I did, didn't noticed it, damm right foot is always going to the floor), I just watch my wideband and tune it. Also watch my vac/boost gauge.
