It's not the original exhaust. I got an LCE header about 5 years ago when thee stock manifold cracked. This is in the tube that connects the header to the cat, it's still in great shape. I've got a friend that does marine exhaust and let him have the pipe, he was going to take it to his shop and see if he could work something out for me getting the old studs out. If not, I'm going to try the hose clamps on Monday. Then maybe later I'll cut the welds and weld on a new bung if I can source one.

On a side note, if you get an LCE header, change out the studs for a higher grade fastener before install! I got 2 grade 10.9 metric bolts and cut the heads off with a dremel. Local hardware store didn't have high grade metric studs, thats why I got the bolts.
