i'm putting a z6 in my 89 cx and i want to run the 4-1 stillen header(designed for the EG's). it looks like it'll be tough to stick that thing in. i've tried taking out my stock manifold as one piece and it's impossible to take out. how can it be done, if at all possible?

 

2 ways put the header in while you swap the motor or there are 4 bolt that hold the front crossmember on the one that have the stablizers(?) that run to the bottom of the bottom control arm and hold it down but it a pain
