That looks like a very nice product improvement!

I checked with FFR the first thing I saw these. Very happy that they confirmed I'll be receiving these with the kit, which by the way must be somewhere in the Atlantic right now.
Now consider grabbing some Adjustment Wedges from Mark Reynolds at Breeze Automotive and all will be right with the world.

Between the new headers and some adjustment wedges you should be able to really nail the pipe location with little difficulty.
No Excrement Dick Tracy; however, we all know that getting the angle of the dangle spot on perfect may need a little extra help unless you fab up your own headers like some of us did. ..Heck, some of us (Meaning Me) are so OCD that we (Me) even shortened the wheelbase to center the rear wheels since Factory Five didn't.

FFinisher Your post was helpful for me. Thanks.

Adjustment is nice if it stays adusted. J-tube ball joint does not stay in place. The headers has 3 bolts vs 2. It should help.
If not, it would be easy to tack weld in place.
Are these only for the Coyote or are they for all 302's? They don't seem to be under the Parts tab on the FFR website.
FFR MKIV ordered 12 July 2019. IRS, Wilwood Brakes, 18" Wheels w/MT tires, power steering, EFI, Heat. 347 Dart w/TKO-600 by Mike Forte, Holley FI, MSD coil and CD box. All new, no donor build.
I do admit that they looked “busy” the first time I saw them. But the function ability can’t be denied! I’d probably set them up and get them tig welded before cutting off the collars.
FFR 5136 Started as a donor...donor guages, engine, trans,etc. Now...TFS street intake,stage 1 cam, GT40p's,24# injectors and 80mm MAF,70mm TB,Z-spec t-5, and PSE Halibrand wrapped with Nitto 555 G2’s. My ever evolving dream car!!
From what I understand the 25th anniversary cars will be using All New Molds that addresses the off-center rear wheel issue among other problems.
Hopefully those molds will be used for all future MK-4's after all of the 25th Anniversary Special Addition Cars are sold.
Since I don't have the IRS set up so I don't know how much things can be adjusted to minimize the issue.

Based on the 20th anniversary video Dave Smith did, the "new" bodies will be sold for all new kits going forward. Don't know the exact cut-in date. You could ask if yours will be one. Good to see they tucked in the openings a bit. But off-center isn't necessarily the case for all. Gets a lot of discussion I guess, but I personally haven't seen in with my builds. I see you have IRS, and my 20th with IRS is fine.

I bought a new set of these headers for Coyote last month - they're not on the website, just email or call.
Mk4 #8861 Complete kit. Delivered: 27 Apr 2016, currently a roller.
Gen-2 Coyote, clutch, TKO600, midshift, and solid axle from Forte. Many pieces from Breeze and Replicarparts.
Will these header fit and working with a SBF 363 with high port heads. (Exhaust Ports raised .750" over stock)? T
Thank you
For what it’s worth, my sidepipes aligned perfectly using the ball headers with no wedges needed. Also, I got my kit back in January and it came from the new molds. Several needed enhancements that are detailed in one of the 25th anny videos from Dave Smith.
I have these headers and have noticed the side pipes sagging a bit despite the collars being very tight. It was mentioned above that you can tack weld them to prevent the sagging.
Has anyone tried this? Does it work?

Do you have the rear support brackets installed?
Sagging has not been a problem for me. I had to tighten up the bolts at the collars on each side after putting some miles on the car and have not had to touch them since. The rear mount is what seems to hold the exhaust up. The inner solid mount bolt broke on each side and mine are being held up by the rubber hanger only and seem to be doing fine. I guess if I had to do it over, I would not have even used the inner solid mount.

My 2cents. As far as aligning the side pipes...they help. You will ALWAYS need to modify the cut out to some degree. I have worked with 6 cars so far and had to move the cut out on 3 of them enough to have to reglass to backfill. The ball joint gives you a lot but not everything. With the under car pipe bracket in place the sidepipe will still sag after vibration and heat cycle. I would suggest (once they are where you want them) (relative to the body not the chassis) to have them welded up so they don't move turning them into a regular o'l header...da Bat
Can someone confirm that the Coyote headers sold by factory five now have the new flange and collars that are adjustable?
See post #19

Thats the only style of header that Factory Five now sells. Just look at their parts site.

I did look at the parts site and for the coyote they only show it without the connector. Thanks again for filling me in.
Bought some of these new headers (302) for my Gen III coupe from the FFR web page.
Fit and alignment is great and no more need for sandwiches of wedges and gaskets.
Lighter (stainless steel) than the old ones by a few lbs.
Mine do sag at the ball couplers- the bolts are not fully threaded and the nuts are the end of the threads and can't be tightened any further- just need to get some washers under the bolt heads.
