You have different undercarriage obstacles to plan your line based on, and some stuff is more likely to grab for that reason (like big ledges or shelves) but its actually easier to negotiate other obstacles when theyre inboarded at the frame side. Also since they sorta follow the driveshaft you will hit anything that it would have hit.

Those were some of my early ideas and still something I'm considering if passing the frame gets too complicated. The FlowMaster outlaw race mufflers would work in that space perfectly. However I'm not sure how awful it would sound with an in-line 6.
Once I crush the exhaust on some rocks I'll be going tgis route. On my new wheeling 80.
I have used this ruffstuff brackets at the frame where it starts going inwards giving me me about 15 degrees of triangulation for the lowers, pretty tight on the driver side as gas tank is in the way. For the uppers, I did a custom mount at the axle and gave them 60 degrees of separation to get close to the 70 perc rule , this into the existing frame cross member .
Hard to tell from pics but the only one I have as of now.

Interesting. I have lots of questions. What axle is this? What are those rear-facing brackets for? Any more picture of the upper truss and where the upper links will attach? Gas tank?

Not sure what the axle itself is but the rear facing brackets are disc brake brackets. Obviously not OEM.

Whats the geometry of that? I suspect it is a little neurotic
To all
Geometry seemed to work well on the calculator, obviously will know better when the truck is drivable ....
The rear axle is a 609, 64.25” WMS with 35 spline shafts centered diff ( had it on another project that never happened). Converted to a gm6 lug and indeed those are the caliper brackets.
I haven’t made the frame upper link mounts yet as I am still contemplating the orientation.
With the ruffstuff brackets there’s really about 1/4” to 0 of an inch before hitting the fuel tank cover, which can be trimmed. That’s where I found the limit for the length of the lowers. Obvious fuel tank has to be removed to do this job.
I can take better pics in a couple of days when I get back into the project. Just hate to clutter a nice thread like this as I enjoy reading the tech part only.

Good looking setup. And by all means please post pics in here! I enjoy seeing different setups as I'm sure everybody else does. My main requirement is keeping the gas tank intact, not looking to run a fuel cell inside the cab for now. Not sure if you've seen Nukegoat's thread yet but he did a good job with the rear setup. Was able to keep the gas tank as-is and triangulate the lowers without hitting the gas tank. I'll be running a wishbone upper and using the stock upper frame mounts.

Back to the exhaust discussion...this is the muffler I think would work well to run a short exhaust alongside the outer frame dumped right before the rear tire. It's only 4.5" in diameter and comes in two versions; 6" short and 11" long.

815425S-Outlaw Race Muffler Short 409S – 2.50 in. Center In Center Out – Aggressive
All of the other Flowmaster mufflers have a much wider can which probably wouldn't fit under the rocker alongside the frame.
This was the only video I could find of an inline 6 with the Outlaw series mufflers. It's loud as hell, but doesn't sound as bad as I expected. This guy is running without cats so mine would be quieter for sure...

Nukegoats build is epic, one of my favorite builds here on the forum as well as yours.
Not sure if wrote it correctly, with my setup I am able to keep the stock fuel tank. I just have to trim the flimsy tank skid plate.
I have pushed the axle back just enough for the upper axle mounts to clear that cross member.
I hope to have everything done by this weekend, will post the results when done.

Damn, as if this thread didn't already go to 11, we're there now!

No way in hell after reading the description provided from Flowmaster about the Outlaw Race muffler would i mount one on my truck.
What about one of these? I love the idea of running this outboard of the frame and dumping before the RR tire, easy to add heat shield above it too!

There was a discussion about those being too restrictive and heating up the exhaust before the muffler. Booger ended up punching out the core to make it work. These look too big to run outside the frame if you have to keep both cats. I'd rather deal with the noise than run a muffler that's too restrictive for our trucks.
Random 3 link nonsense...

Had no idea they would be that restrictive! Thanks for the links, truck is looking good man. You found a home for your old beefed up lower links?
Where can I read about this white cruiser on Pitbull Rocker? ))
Nice work! That's kinda what I was planning to do; buy a bunch of pieces and try to build it myself. But because I need to keep both cats the spot where most guys go over the frame is out of the question. I did find another spot where it could cross over but that is further back, I think that's where Nuke routed his as well. We shall see.
Last time I checked I think the lowers will be about 40" bolt-to-bolt. You can kinda see them in @nukegoat rig in this picture. He ran this setup while on 37s so perhaps he can chime in if he thinks they hung too lower before going to a much bigger tire.
