Exhaust leak from headers..., How do I fix this? Options

[XSTeknique]

Ever since I got my HP headers put on, there's been an exhaust leak. I even replaced the manifold gasket with a new Toyota one. I can smell and hear it, what's the best way to fix this? I'm pretty sure the gaskets from the headers are all there, but keep in mind some of custom fitted. Any help is appreciated.

sooo...if you realise that it's "header" why would you type "headers"?

and, yuo was intentional, skillet.

anyway...contribution...

check 'round the o2 sensors. did you weld an extra section of your O.G. downpipe?

if so, check that. who welded it? you? or pro's?

it's definately not a prob. with HP headers, as mine is fine. even transplanted from the old engine to the new one.
