the only thing I think would give you any issues is the O2, probably have to change it to a 3 wire to keep it hot. I was planning on doing a very similar thing on mine

WTF is an "overlander"?I’m want to slowly build it into an overlander.
Exhaust sizing depends on displacement X RPM. Dual 2.5" pipes on a typical 350 is not too large, but larger than absolutely needed especially in a lower-RPM application like a pickup.My questions are if the 2.5” pipe would be too big for my stock 350,
Wild Guess: "X-Pipe Muffler" is a marketing gimmick. Walk away. Install a REAL "X-pipe" and a pair of mufflers.if just the x pipe muffler would be enough for proper scavenging, and if the muffler would be too loud. I don’t want it to be excessively loud, just a nice low rumble to it.
Any exhaust crossover--"H-pipe" or "X-pipe" (even the exhaust crossover in non-Vortec intake manifolds, to a limited extent) promotes lower exhaust restriction by allowing the exhaust streams from both cylinder banks to share muffler volume.How important is the X-pipe and what does it do?
My dual system doesn't have one - each cylinder bank is completely independent of the other - should it be that way? Am I losing out on anything? (That's on a 350 Vortec BTW).
Not nearly that simple. Note that the Craftsman race truck pictured in this thread--which runs at high RPM--has an H-pipe.X pipe is for higher RPMs, H for low end.
Note the "H-pipe" on a high-rpm "race truck".Check out this exhaust system. I took these pics back in 08 when my son and I went to the races in Phoenix. This is a mock-up of a truck on a rotisserie when it was the Craftsman series. Note the Tri-Y headers and giant H pipe.
That makes me moist. I've had a Truck-Arm-coil-spring fetish for decades. Even considered adding a Truck-Arm rear suspension to my El Camino.How about this for a suspension?

Most folks don't understand that the Truck Arm coil spring rear suspension was almost universally used in NASCAR (and the Craftsman Truck racing series) for DECADES; but it was standard equipment on Chevy and GMC 1/2- and 3/4-ton pickups starting in 1960. I don't know when it went away in favor of ****** leaf springs again--certainly for the "new" trucks in...1972? I think they were selectively putting the leafs back under the pickups earlier than that, though.
If you can check out Engine masters episode 22. "Straight Exhaust vs. H-Pipe vs. X-Pipe!" it will answer a few questions for you.

Don't learn the WRONG things from this video. These guys are infamous for half-truths, partial explanations, assumptions, and...well..bullshit.Answered one question. Ain't worth the grief I'd have trying put either a X or H pipe at the same distance from the manifolds on a dual that runs up the same side of the truck.

That's what I did on the '88 K1500. 3" converter, 3" single pipe, 3" in-and-out muffler, 3" tailpipe.#2 faster, easier, cheaper to run a single muffler/tailpipe...probably same power result as well
