What is this gasket used for?

[NYGarageQueen]

I tried searching autozone and advanced auto, as well as rock auto for that flange gasket after the cats that run to the h-pipe.

They all come up with this thing:

That, does not fit at all. I tried searching 03 and 04 ....... does not even line up what so ever.

no clue wtf that is for.

Just a guess, Cobra manifold?

Lucky for you I just went thru this.

Nobody local carries a Marauder specific gasket, some can order at the price of $9.00 each.

After four failed attempts, I bought a pair for a 2003 grand marquis for $3.50.

Well what do you know, a perfect fit...

Looks like the passenger side header to down tube on my car. When i put my headers on, i tore up the pass. side gasket and had to go to my LAPS/Pep Boys, rite off i ordered a gasket for A " '03 Mach 1 passenger side exhaust gasket". Luckily i had my old 1 to show them. Matched up perfect!.... some times You gotta cheat the LAPS a little.....

That's exactly what the FLAPS by me carried. I never found an alternative. Just reused the ones that were on the car. No leaks yet. Looks like JustBob found the solution

Right side Mustang 4.6 manifold to catalytic converter gasket. Now if you had DR's Cobra setup, it would work. :D

The gasket is for the passenger side shorty header-to-mustang H/X pipe. The metal one in the pic is the one you want not the black gasket material one. (those blow out)
