Can't wait to see what you have in store for the first gen A bodies.
I'd be all for developing a swap system for those cars, but I've not heard from management whether we'll be doing anything for them or not. I guess we'll just have to wait and see.

I would bet some of it would be the same and others might require some minor tweaking such as the headers. I think most of the work has already been done.

Knowing that the 64-67 is on the list...please keep in mind that guys like me have the engine in the factory location using the 12611 mounts. Changes to location at this juncture is not feasible for headers

The development goal for the 66-67 system components will closely follow that of the 68-72 application, which is to fix the outstanding issues related to tie-rod clearance with the oil pan and the ability to acheive optimized U-joint operation angles without having to cut up the floor/tunnel in most transmission applications. Once that is accomplished, headers and a complete exhaust system will be designed that maximize ground clearance. In order to make all this happen, the use of the stock frame stands/engine mounts and flat adapter plates has to be abandoned and replaced with application-specific engine brackets and 4th-gen F-body motor mounts. This provides the added benefit of also being able to run certain low-mount A/C compressors, which has been well received by many of those who've been following this thread. I'm hopeful that the headers will also be installable will the stock frame stands and flat plates as the 68-72 headers were able to be, but there won't be any extraordinary measures taken to ensure that they will.

Let me know when your ready, I'll bring my 67 up for you to play with.
Thanks for the offer 67Skylark. I'm using a 67 Chevelle out of the Holley vehicle pool to get started on and we'll see what develops from there.
looking forward to a pan that has a baffle kit, I cut up an F-body pan and got driveline angles correct without limiting turn radius, but can get the oil light to flash under hard braking. I've already move the brake valve up to the master cylinder and dented one down tube of the headers to clear steering.

The components will all be based around the fitment geometry of the Holley 302-2 oil pan, which does have a trap door baffle assembly available for it. I was able to design the 68-72 A-body headers so that they would fit without having to relocate the brake proportioning valve and am hopeful for the same results with the 66-67 application.
I spent the afternoon installing the exhaust system I prototyped on the wagon last week on an 1971 El Camino to validate the fitment. Everything went as expected and confirms this system will be installable on all wagon, El Caminos and 4-door applications. For those just checking in, there's also a specific system for the 2-door cars that exits out under the rear bumper valance. Here's a couple of pics of today's fitment check...
We're not quite there yet as there is still some production tooling design and construction work that needs to take place. The 3" 2-door system will become available first within a couple of weeks and the 2.5" version of that system and the El Camino/wagon/4-door systems will follow a few weeks afterwards.

The Hooker 2-door A-body systems (2.5" and 3"), which I haven't shown yet, have a similar exit style to the tailpipes you've posted. The big differences between the two however would be the ability of the Hooker system to provide far greater rear tire clearance than the tailpipes you've highlighted, and the fact that the Hooker parts are 304ss. These two images depict the routing and tire clearance capability of the Hooker 1968-72 A-body 2-door 3" exhaust system...your rear tires will hit the frame before the tubing of the exhaust system.
Are the pipes in your exhaust systems 304 ss or 409 ss ? The mufflers on the website say 304 but no mention of the pipe material other than ss.
The initial release of the systems will be exclusively 304ss, which follows the standard make-up of products in the Hooker Blackheart line. There are applications where we also offer 409ss versions of the exhaust systems, such as the 3rd and 4th gen F-bodies, but this will not be one of them unless customer feedback tells us it's something we should be offering.
