Doug's header / tti exhaust issue

Ok guys and girls! I just installed new Doug's headers on my 67 dart small block! Now I am installing the tti 2 1/2 exhaust with x pipe! The headers are wider then the tti exhaust pipes that are coming up to the header flang! Has anyone else run into this? If so, what's the secret?
Looks like it is time to get out the sawzall and the welder.
I had to modify my custom built H pipe exhaust when I installed a set of TTI headers in my Barracuda.
