Has to deal with backpressure. Im not an exhaust expert but im going to say you probably need some more backpressure. What size pipe you have? probably 3" all the way out right?

i know sometimes these trucks need the backpressure supplied from the cats. Putting on a set of hi-flow cats will probably stop the popping and restore some bottom end that u may have lost too.

I can't believe all these posts about "needing" back-pressure. Trying to re-burn exhaust is bad.

 

What you want is a properly designed system that scavenges the exhaust gasses completely (ie no back pressure at all). The popping sound is proof that your current setup is not doing this. You can do several things to improve scavenging without adding restriction (aka back pressure) to the system. It'll take some time and money, but adding or moving H-pipes or X-pipes, changing pipe diameter, length and/or manifolds should give you the desired results.

np sense of humour = boring thread!

I must say that I LOL'd when I saw your post. It's almost as good as the one you made about gambling & smoking!

 

Keep bringing the humor... some of us "get it". :thumbs:

    • Did you ever get this worked out? Mike is doing the two start thing now too. This is after a new camera back in December. 
    • I’m doing an experiment on a vehicle I don’t have much money in. I’m going by the premise that after they last 100K miles they were no mechanical problems with assembly. Or defects with the parts. With oil changes by the minder for the first 127K miles when I acquired it. I quickly went through low mileage oil changes then settled on 5k oil changes with close to 170K miles on the vehicle currently. I did have the option to turn off the cylinder deactivation. I didn’t on this vehicle because in ECONOMY mode at least half the time. It should be a no brainer frequent oil changes are the key. The manufacturer gets away with the long oil changes with its severe service  maintenance. Just ask them what is normal. 
    • Even set to "recirculated", the air pushes out and is hot. I have noticed that sometime it doesn't want to switch between recirculated/vented air. Say it is set to Circulated Air and I want to switch to Vented, when I click the Vented button, it just quickly lights up/clicks and immediatly switches back to Circulated. It's done this a few times now. So maybe it is an actuator getting stuck? But then, that doesn't explain the hot air when everything is off does it?
    • I wonder what the price is out at the coast, Big Sur or other out of the way locations as I bet they are charging quite a premium over the in land pumps. 
    • Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.
