So, have we established what the SLR headers will do for the 3.3 liter emmissions? If anything at all..

My exhaust manifold has been cracked for a while, if it get's worse then I might fail inspection for safety here in NY, not emmissions.

If/when I need to replace the manifold, I wanted to replace it with the SLR headers so I wont have the cracking problem again.
I am not removing the cat. converters on my truck.
I just wanted to make sure that I'm not causing any potential problems in the future.

Anyone?

All of the previous cars I've run headers on before were emmissions exempt because they were 25 years old or older. I never dealt with installing headers on an emmissions car.
