I have the mid Pacesetters and have all 12 bolts removed. I got the drivers side out the top easily but does the passenger (stock manifold) come out the bottom or top? Do i need to remove anything to get the old one out and the new one in?

Take off the alternator if you haven't already done so and the oil dipstick. It should come right out the top. It takes some maneuvering though.

yea buddy you just gotta give it hell

I have installed both sides and the only thing i removed was the dip stick. The passenger side came out the bottom with a little wiggle and the new passenger side almost fell through there was so much room. The drivers side came out easily from the top and went back in almost as easily. I see many things people suggest removing lots of parts but it can be done with very limited removals. I even left the air pipes and the 02's on. I assume the LT's are a lot more difficult but im glad i choose the Pacesetters mid's. Hope this helps future jobs.

Yeah, with the LTs, you have alot of header to wedge in a small spot.
