I'm looking for a used 180 degree header and exhaust system for my Pantera. I'm not sure that it will work for me as I need to stow my targa roof back there and want to make sure it will all fit and not roast the paint off my roof section. That's why I'm looking for something used and reasonably priced. I've already talked with Ron McCall about this, and he has nothing used for me. I'm really hoping to find something soon as I really want to give it a shot asap! Thanks all.

Hum? I would think that you need something made especially for your situation?
Ron would be the guy to talk to about that? Frankly, there just isn't much room to play with back there at all. You likely will need a custom trunk liner to go with the headers.
Not attempting to be sarcastic about this at all but good luck with that one. I'm doubtful that combination is even possible? You are going to need some kind of an alchemist at the very least? Even the stock exhaust underneath has the tendency to keep things warmed up a bit.
Over the top you can just barbecue burgers on. 
Mine is coated with cerakote. It does an excellent job of keeping the temp down in the engine bay.

Mine are ceramic coated also. It keeps the temps down from broil to roast and keeps the burgers from sticking to the header tubes. 
Hint: don't try to carry your groceries back there.
180 degree headers fill the entire space behind the block and over the top of the ZF in order to exit the car either in the center opening if you deleted your AC or out the exhaust cut outs like Gary Hall did it. Any targa roof would be above them and melt instantly.
As an alternative, leave the targa top at home and have an “emergency” canvas top made, that you can stow in the front trunk or inside the passenger compartment.
@marlinjack ‘s idea actually seems the best way to go… Lamborghini did it very cunningly as he pointed out!! I think it gets roasted if you put it inside!
check the size of your target top if it’s an option….

But, is That a Lamborghini, Or a 'Zezeta Moroder' Twin Engine V16?? 2 V-8's Mounted INLINE Laterally, with the Crankshafts Connected at the Transaxle. That's why the Rearend is Over 8 Feet Wide, and can not be driven on Americas' Highways...Legally!
It’s a Lamborghini…
Here is the 
undeniably body done by Lamborghini engineers as well…. Dual Engine sounded awful when not under load- Like five trash cans filled with running mixers, 2 cement blocks and five cats inside rolling down a hillside! Just can’t hide your roots - lol The spider had a soft top that was behind the seats when not in use!

I appreciate the suggestion, but don't like that look, so I'm not going to do that. I like that you were literally thinking outside the box!

I really like the idea of having a foldable canvas roof made and will definitely explore that idea... Thanks for suggesting it!
In the meantime, does anyone have a 180 degree exhaust they might want to part with?

I've seen this done by OEMs. If I'm not mistaken, both Lamborghini and Porsche have supplied emergency canvas tops for targa top models, so the owner can leave the targa top at home. The tops in question were not like tonneau covers that used snaps to attach them. The ones I'm thinking of have a rigid, but foldable, frame. When they were unfolded, the canvas was pulled tight and they installed exactly the way the targa top did.
Another idea would be to have a new targa top made in two pieces, that joined in the center, exactly like the Porsche Carrera GT. Having the top in two pieces might give you greater "stow-ability".
Did you ever say what engine/head configuration you are using?
I'm using the stock Aussie 351C block and heads that came with the car.
As I recall the 2Vand 4v heads have different ports so the header exhaust flange may or may not mate up for a given set of headers. Do you still have your 5S?
husker,
Yes, I still have my 5S, that's what the 180s would be for.
I thought the 5Ss used a Windsor.
I don't see modifying a trunk insert as being a big deal - it's just a matter of throwing hours at it. As everyone above has said though, your going to end up with a fairly small, very hot, and relatively expensive area.

Gt5-S use Windsor and Clevelands
