Let's see your 4x4 dual exhaust setups

Alrighty guys, sometime in the near future I want to put some longtubes, and duals on my truck and dump them with turn-downs before the back axle...

There is sort of a tight gap between the transfer case and the left frame rail so 4x4 guys please post your dual exhaust setups!

Thanks,
Steven

Manually tranny eh?

'didn't wanna deal with the headache so both tubes parallel the right frame rail...:

To removable slip-fit joints and band clamps...:

To some small and compact 2.5-inch Moroso Spiral Flow mufflers:

Here is the set-up with a prototype exhaust tip (cardboard).

The fabbed exhaust tip:

That seems to be kinda popular, running both on the right frame rail, I'd kinda like to run one pipe on each frame rail if I could, now I've got a C6 so should that make this easier or harder?

Stock configuration uses a stock Y-pipe to a single exhaust.

Long tubes and duals is waaay easier than a manual setup..... A good muffler shop will be able to snake their way past the tranny and down the left frame rail.

Alternatively, LMC makes a kit for 4x4s with auto trans on page 138:

I did it on my '78 that had a 400/NP435/205 combo. IIRC anyway. It had the part-time transfer case, whichever one that is. I had Dynomax headers (junk!) and 2.5" duals. The driver's side pipe went up over the trans crossmember, and had to bend outward to clear the transfer case. It was a little tight, but never had any problems.

No pics, this was long before we had a digital camera.

I have flow tech headers, run along each frame rail into 2 chamber flowmasters with turn downs. All hidden unless you crawl under the truck

I don't have any good pictures but the pipes come off of the headers and go down below the crossmember and then back up between the frame rails and dump towards the front/middle of the bed.

Here's the most recent vids (390/headers 2.5" pipes no crossover and flowmaster super 10s):
