Okay, here are the pics. 7 of them. These exhaust manifolds are from an '00 Z28, I used the Z28 driver side on the Fiero front side, and the Z28 passenger side on the Fiero rear side. Idk if it'll clear so well if you use an automatic, but these pics should show the excellent fit with the F40. Here goes:

For that first pic, tilt your head over onto your right shoulder.

Wow... That is a nice and clean block!... Do you have a shot of the exhaust route or drawing you plan on using? We are planning to try to do the muffler collection at the rear without doing too much trunk cutting !! LOL
I should have some more pics tomorrow... Also, I am looking for a good sounding exhaust... minus cat of course as the old girl drops off smog tests this year,, Flowmaster is out.. bad experience and fellow Fiero guys experience as well... Looking for a warm, vette like sound... smooth but aggressive... Ideas anyone....? A real full note but not raspy sound on any end..
I know... I ask a lot of questions.... PS... I really like Ricks video...and a sound something like his maybe a note lower?

I'm going to go with custom headers, these manifolds are only good to 400 rwhp, and I want more. I was reading on www.ls1tech.com, someone had an LS1, with LS6 heads and intake manifold, and these exhaust manifolds, in a '32 Ford. With a manual trans. They ordered a custom 218/230 cam, and made 400 rwhp. You'd have less with an automatic, but your Ls4 block already has the correct heads to do that, and it can be bored to 5.7L safely.
If I was keeping these manifolds, I'd put a bend on the front side, to put a cat in front of the cradle's cross-beam, then the exhaust could pass under that hump in the cradle, and under the "front" of the oil pan. Speaking of which, I'm going with an '05 Corvette oil pan. If you plan on road racing or autocrossing, it's better at controlling oil in all 4 directions than the LS4 pan. I can get you the GM part number if you want to buy a new one.
Anyway, if there's anything else I can help you with, just name it.
