What to use to temporarily seal exhaust leak at the Y?
I've got a couple leaks where the MC's meet the Y pipe which is causing the car to run like absolute crap with it leaking before the 02's. I need to be able to drive it to MD which is about an hour away, so I need temporary fix in the meantime until the exhaust gets welded up. Any ideas?

Fold up a bunch of aluminum foil into like 2" wide strips that are long enough to wrap around the pipe at the joint, then put a band clamp over that and tighten the **** out of it. It should conform to the shapes and fill in the gaps. Smear a little RTV right on the joint before putting the foil on for even more leak-seal-age.

Aluminum HVAC tape (comes in a large roll at
Home Depot, or a much smaller roll for the same
price at auto parts stores). Few turns of that
should do it, especially if you put it inside a
band clamp.

some aluminum foil or tape should work fine w/some clamps... thats what i used when i had a 3" gap in my y-pipe right before the cat.... you say its at the header/y gasket? ...not much you can do there.... it's not like an exhaust leak is going to permenatly damage your car if your just drivin it for an hour or so... my friend has been driving with one for six-months

Get some Permatex RTV Copper Gasket Maker. Loosen the clamps up and slide them back. Then apply the Copper Gasket Maker around where the pipes join. Spread it all the way around with your finger. Slide the clamps back over the joint, and tighten them up. Let the Copper Gasket Maker dry overnight before you crank the car up. This worked for me.

Flange leaking? Fix

If it’s leaking where one pipe slides inside another, take an angle grinder and cut two slits 180 degrees apart on the outer pipe. Then use a band clamp. When you tighten it, the slits will give it room to compress. Won’t be perfect but should stop significant leaks.
Unless your outer pipe is already slotted. In which case, feel free to insult me as a complete moron
