I have talked to a couple LS3 owners who have installed Speed Engineering headers. One of them installed the 2" headers with no fitment issues. Another did the 1-7/8" and it rubbed the steering shaft. A little massaging of the header with a ball peen hammer would take care of that.

Personally, I purchased ARH 1-7/8" headers with cats from @Randy@RaginRacin here on the forum. Outstanding deal on the headers. Email him for a price and see what he can do. ARH fitment is consistent from what I have read on the forum.

Hope this helps!

I talked to Doug I believe at ECS a couple years ago and he told me technically you dont need headers with a supercharger unless you’re trying to squeeze every bit of HP and I’m not. Decisions to make!
