K I just gotta ask.... Why do you want to know the weight difference?

 

No real reason.
I'm a numbers guy and i've never owned a full size truck prior to this Laramie, always cars and bikes. So when modding dropping weight is always a bonus.
I know it's pointless in a 5800 lbs truck, but I'm always curious about numbers anyway.

 

Well seeing as the stock muffler is the size of a water heater tank.. i am sure you will drop a few pounds no matter what. If you decide to go with the mufflex system.. Weigh it before install and then weight the old system after. It won't make any noticable difference.. if you are going for weight drop for any reason, only way your getting that is to gut the back seats, spare tire, tail gate and every toy and added feature that weighs something. We all know you don't want to be doing that.. I say it may be 10 pounds lighter for the muffler.. but never heard of anyone weighing it all so just a rough guess.

 

I was going to guess 10-15 lbs each too.
No I have no interest in trying to make my truck a lightweight.
I bought the Laramie CC 4x4 for it's luxury AND truck abilities combined, not because I was looking for a fast truck.
To be honest, and not to offend anyone, I see little reason to buy a truck with the intent and desire to make it fast, that's what cars and bikes are for. That's like buy a Honda Goldwing with the desire and intent to carve canyons??

I just didn't want to ADD any weight to the truck.
Looking for a bit more aggressive sound that's about it. But if it comes at the expense of adding weight, then I'd pass.
But for $275 for the Mufflex mufflers, having a bit more aggressive sound it's worth that much.

 

Maybe the shipping weight is listed by online vendors selling that setup. Maybe give a rough idea.

 

You definitely won't be adding weight by going with the mufflex system. Your new muffler will be about half the size of the stock one so you'll at least lose a few pounds.

 

The stock muffler weighs 38lbs. I was going to scrap it, but for 7 cents a pound, $2.66, the heck with it I'll keep it.

 

38 lbs each??? or for both?

 

There isn't going to be huge gains.... some people say a retaining a little back pressure actually helps with the low end torque. Not sure if you'd notice a difference or not though. Realistically swapping out the stock Y-pipe and muffler will free up about as much flow as you need unless you plan on supercharging the truck.

 

Driver72, you will lose bottom end response if purely stock. Especially if your MDS is active. That is the main reason for the "POORLY" designed y-pipe. 4cylinder backpressure. Now if you deactivate your MDS by way of ERS or a tuner, then yes, a free flowing, true dual you shall benefit from.:smileup:

 

This is true, I forgot about the MDS.
And yes, backpressure definitely helps with lower end torque, but hurts higher end horsepower.

A perfect example is Mustang's 5.0 liter engine.
In the GT it makes 390 lbs ft of torque.
But in the Boss 302 which has a freer flowing exhaust, and intake manifold, which gave it 24 more hp on the top end, losses 10 lbs ft of torque.


But again, I forgot about the MDS, taking away a bit of low end torque will mean the MDS will not work as often and cut into fuel economy too.

But I'm sure there is a solid 10-15 hp in the mid to upper range of the rpm to be had....this is my first pick up truck so I still often think in performance car mindset and not low end torque which nice for a 5800 lbs truck too.
