Help: Exhaust Leak
Good afternoon,
I need help trying to figure out which exhaust gasket I need to replace n my 1991 Lexus LS 400. I tried exhaust tape to get me going but the pressure from the exhaust blew off the tape. That was the dumbest thing to do but anyway it's Friday and I wanted to go out and buy the gasket(s) to resolve my exhaust leak issue. Problem is I am not sure of the part name and was wondering if someone could help me.
It seems as if the exhaust leak is coming from the front of the car on both sides driver and passenger side right before the oxygen sensor. If I am not mistaken, that would be the catalytic gasket?
Please help.
Thanks!

I believe it is the mid pipe because I tried to patch the gap, it seems as if the gaskets fell out or the previous owner toke them out and didn't completely tighten the bolts. I remember that when I tried to patch the gap with metal tape, I kept banging my hand on the oxygen sensor. How much would it cost to replace the gaskets (parts and labor)?

What have you guys' exhaust leaks sounded like? Does it sounds kind of like a hissing noise or a loud ticking? My car is making a hissing noise underneath and it goes away at idle but starts hissing just above idle. It's coming from under the car.
I second the PB blaster suggestions, make sure you let that stuff sit overnight on the bolts and you'll have a much easier time in the morning!

Forgot about the infamous EGR tube. I've read two different theories regarding replacing it. I've mostly heard that the transmission must be removed but I've also heard that it can be done without removing the trans. Which way did you do yours?
