Is there a fix for leaking slip-fit LT headers?

[FOXCOUPE]

When i had these headers installed about a year ago there was a slight leak but it never really bothered me. Now i've got a pair of cams and custom tune and she don't run so good. I had the slip-fit section's welded up which helped a lot but since u can't weld it all the way around the tubes i still have a very small leak. I think i saw someone use a T-bolt clamp but looking at them i don't see how the clamp could generate enough force to squeeze the header tube.

We've used the hightemp exhaust puddy on my buddies cobra. Sorry don't know the exact name Dad has a bunch at the exhaust shop he works at we just coat everything and let it rock.

Yeap, I did the same - just covered it with the muffler putty/cement.

The area where it's leaking is inbetween the tubes on the inside so i can't get in there with any putty or muffler cement. The only thing i can try to do at this point slip somekind of thin clamp over that one tube.

Mine does the same thing. I am actually running 10% leaner from one bank to the other, and I believe it's because of this leak.
