Quick update guys. The fbody headers didn't work. However had a guy over on LS1Tech suggest that shorties from a Silverado SS. Got em in and they work great. So I'll be making a j-pipe to connect to the side exhaust for now. I'll end up doing a 4 into 4 setup but that's not gonna happen till the car gets on the road. Funding won't allow it at this time. Here's some pics:
