The way i found an elusive leak on my Trans Am headers...Wait until cold start car and IMMEDIATELY move your bare hands along the headers collectors etc as close to them without touching them as possible. You should be able to feel the air pressure pushing out through the leak. But hurry they will get hot pretty quick!
It might take a couple of tries but it worked for me.........Lyle

I had a problem sort of like what your going through but it was in my 5 oh! I went through everything 10 times befor I took off the MAC long tubes and measured the thickness and found out that one was warped. I had to grind it down very carefully. It fixed my problem!!
However, I had a small tic and knew that it was the flange. I wrenched everything I could to fix the leak without success. I even tried two gaskets befor grinding. If you have no tic at the header flange you dont have a leak there.
#1 Check all your hoses and tubes after the install from hell
#2 Hope for some cold weather so you can see the exhust leak
#3 At night, when its cold use flashlight you may be able to see it :headbang:
#4 When the engine cold, use your hands right away to sweep the aeras of fitment. :alcoholic
#5 Get your car on a lift :biggthump
P.S.
NOT running cats, you may be smelling the excess unburnt fumes that you may not be use to
Good luck

How to find a header leak:
1) Fill spray bottle with water and a bit of dish soap.
2) Start engine
3) Spray water on flanges, collectors, etc. Anywhere it could leak
4) Look for air bubbles. The leaking exhaust gas will cause the soapy water to bubble.
Or you could use Snoop. But I wouldn't know where to find that stuff.
