Now if you've turned off the MDS with a tuner, whole different ballgame. Now you need engine to breath better. Headers into hi-flo cats, into hi-flo performance exhaust, but it still needs to be sized right for the RPM/HP/torque range engine will operate in. It all has to match or it will not run as it should.
Sounds all good and cushy.....

Then how do you explain those of us who have scrapped the OEM Y-pipe out for a free flowing one, and have encountered ZERO issues?

I don't buy it either.

I think parts of a lesser quality are as much to blame as incompetent hands.....

Ok Cliff here is my thoughts.
Symptoms
1) Burning oil
2) Low compression
3) ticking noise, probably valvetrain clatter.
Me thinks you got a bad head or gasket, or there is a valve on it's way to the crapper.
Change the oil with a high mileage formula, this should help reduce noise for a few miles. 100-200 or so. Put it back to factory and trade it in.
Your other option is have a reputable mechanic tear the heads off the engine and see what's what in there.
Best of luck to you bud, I hate car dealerships who make lame arse excuses for an obvious mechanical failure. Been there.
That almost sounds like a valve guide that's worn causing oil from the heads to leak onto the valve seat and intake/exhaust port. Over time carbon build up could cause the valve to seat improperly, explaining low compression and potentially cause a valve tick.

Grubrunner, I only said "I think" the y-pipe was designed to work with the MDS system, but it still makes sense to me. The smaller the engine the smaller exhaust you need, fact. When the factory designed the HEMI MDS system, it was designed for MPG, "not" performance. How much time is the MDS engaged while driving? A lot, probably over 90% of all engine run times, "unless its turned off by a tuner". At 55 MPH the throttle blade is barely cracked open which limits air in, which negates the need for a hi-po exhaust going out, no where near the flow limits of stock manifolds/cats.
Will your truck run with the y-pipe and other exhaust mods? Yes, most probably. If you could find a dyno that read low enough to measure 1500 RPM @ 55 MPH, I would bet that with the hi-po exhaust you lost some torque. Will it help at 65 MPH and above? Some. Wide open throttle? Again, some. Remember the stock manifolds/cats? But 1. How long do you drive it at WOT? and 2. The biggest restriction is still the exhaust manifolds/cats. and 3. The ECU is set for "stock" everything. It will accept some changes, but when those changes go out of the set limits it cannot over ride itself to keep up with them. That's when codes are set and engine starts doing goofy things.

Well, I guess you never saw the Dateline NBC episodes, where the toolbag Chrysler Workers were all out at a park in Michigan at lunchtime boozing it up with 40 ozer's, then going back and building our vehicles.....you couldn't assemble a ashtray let alone a motor..... Oh, you're seeing 3 of these crankshafts? Just pick the one in the middle! No one will notice.

Exactly man! I say the same thing. Look I love my ram & think by far for what it cost even though it wasn't cheap you get so much more than chevy & Ford in the same model year / class truck compared to mine were a joke. Too much money w/ less style ,performance & interior/ ride comfort. That said. My ram had exterior body issues, paint issues , interior color match issues & there's still all these "oh thats normal" corks like the 3/4 tank clunk & the funky transmission shifting like a guy w/ turrets not knowing what gear to push into. Not to mention the chrysler customer service is like lois's dad from family guy. "there's nothing wrong w/ these trucks so tuff"!

Can't believe I'm saying this again. It truly pains me. But are any of you regular cab (Mexican-built) guys having these problems?

Knock on wood. Other than crooked steering wheel, nothing. At 12K runs flawlessly.
