I have an exhaust leak from the bottom of my header has anyone else had this problem

do u have a gasket there?

^^^^^^^^

yeah i found the problem when i took it apart today the spring bolt at the bottom was crooked so i had to replace it

Went threw the same issue..mine turned out to be the doughnut gasket.While I was in there I put on a header.Happy I did.

The doughnut gasket is a problem that a lot of xB owners have. Toyota had a problem with these from 2004 to 2007 when the xB had the echo engine in it. Mine already got replaced 2 or 3 times.
