Great news... the mufflers anyways. The small fires are another matter entirely.
I'm kicking myself in the ass now for not asking you about the mufflers earlier. I remember when we were standing under the car on your lift and I saw those Stainless Works mufflers I meant to ask if they were "turbo" style mufflers (S-path) or the straight through variety-- stainless works makes both!

Obviously you had the "turbo"-style with the S-bend flowpath. Yuck!
If you had stuck a pressure gauge in one of the WB02 taps that would have told the story immediately...
A 5psi drop across the intercooler is still working the turbos harder than they need to be but if you're happy with the power and the IAT is reasonable I'd live with it rather than having to redesign and refab the entire nose of the car.
Next question... I believe a certain Silver twin turbo 69 Camaro in our area also has a stainless works exhaust... he might want to verify what mufflers he has, although based on how the car runs I'm pretty sure he has the straight through style.
