I'm thinking about chopping the stock muffler out and putting in the 12229 magnaflow muffler in its place and keeping everything else in there. The flapper valve should help with the V4 buffeting/helicopter noise and the resonator will abate the resonance AKA "drone". Considering the GMPP Borla system keeps it in place and doesn't suffer from the V4 issues, is telling. Has anyone else tried this combo?

 

ETA: Has anyone looked inside the stock rear resonator? Is it a straight through unit or is it baffled?

Got my 3.5" MBRP on my truck today finally. The stocker came off nice because everything is so new and not driven lol. I just wiggled the factory exhaust out in one piece and threw it up for sale.... spent more time trying to get the GM 4" tip they just ram over the tailpipe off... Gave up as I will destroy that tip before it actually slides off. Had the new one on in about 20 minutes and took it for a drive. Drone is basically null and it just sounds good when you are on the throttle. Even in V4 I didn't notice really anything worth noting for drone. Needless to say I am happy with it.... until I put headers and no cats thus having straight pipe just like my one other truck... lol.

I found this company about a month ago. Their "R" muffler is probably at the top of my list. If you search on YouTube you will find several videos of both the "R" and "TR" muffler on 2014 - 2015 trucks.

Decided to just go ahead and order the 38351 Dynomax system rather than hack up the stock exhaust. Figured the cost of a Magnaflow muffler and the labor to install it would put me at half the cost of a complete system.

I just put that same exhaust on my truck. I had the resonator removed and left the flapper in. The truck was extremely quiet that way. Even when I got on the throttle, I could hardly hear the exhaust. I immediately drove to OSH and bought a 2" hose clamp and opened the valve. I am now happy with the sound. I could hear the drone and it really bugged me. I programmed my truck to remove the AFM. Way better!!!!

Got the 38531 Dynomax system and installed it yesterday at work. It was pretty easy to remove the old exhaust. Once unbolted we moved it back far enough to clear the middle cross-member, the pulled it out towards the front of the truck instead of trying to fish it over the rear axle. The new cat-back went on really easy and everything fit perfect. Only thing that was tricky was installing the tip LOL. It takes quite a bit of cinching down of the clamp on the tip to get it tight on the tailpipe, and the first clamp broke at the nut. Luckily it comes with an extra clamp if you have the longer bed so I just used that one and it tightened down fine.

 

The exhaust sounds great! It's not obnoxious but get your foot in it and it growls! their is a slight "chopper" now in V4 mode at some speeds, but not bad enough to worry about.

 

I also got the AirAid intake installed this morning and it adds some growl to the setup. Didn't get a chance to really drive aggressive with that yet, but it seems to smoothen things out. I am interested to see how the mileage improves with these two mods. A couple of MPG's would be great!

The chopper sound eventually got to me with the Dynomax, so I said if I'm gonna have a chopper, I'm getting one with a bit more sound. So I just took out the VT muffler and put in a Flowmaster Super 40. Much happier now. I also have the Range AFM disabler, so no chopper unless I pull that out.

 

I am giong to convert to FFV soon and get a full tune and tune out AFM though.

Yeah the nice thing is that with this system, you can easily put in any performance muffler with a center/offset layout in it's place if you wanna change it up.

It didn't take but a few days for me to get tired of the chopper sound with the dynomax VT while in V4 mode with light throttle. It was also way too quit to be an aftermarket exhaust at idle and low to med throttle. Did sound good at WOT though.

Exactly why I kept it!

I agree with most of this :). I thought it was ok a Med throttle, but WOT all I could hear was air passing, not a thunderous roar ;).

But anyway, for those on the fence about what exhaust to get, consider this:

 

You can buy this exhaust for $330, and a Magnaflow muffler (for example) for another $100, and end up with a Magnaflow exhaust and save yourself $450, over the $900 Magnaflow system. Don't get me wrong, I REALLY like Magnaflow products, but their price for a cat-back is ridiculous considering you can buy the same thing for almost 1/3 of the price.

      MPG at 600 miles

      By Chuck FB · Posted

      There are probably a few threads talking about fuel mileage but this one seemed to fit the stats I have seen based on my typical local driven route but with different outcomes based on different seasons/temperatures. I have a few hundred pounds of items that consistently ride on the truck at all times such as a bak flip cover, rubber bed mat, tools and extra fuel so I would be something over 8100 lb without me in the truck. All these examples are based on a 100 mile round trip to a town plus running around town so maybe 110 to 120 miles in total for a trip. Using regular fuel and I assume it always has some ethanol in it but don't know the percentage they blend in. Also speed wise I am going at 62 mph and non aggressive driving although less speed yet if its crappy winter condition roads. I am going by an initial reset of the computer generated fuel use numbers averaged over a couple of thousand miles or so for each weather/season so they may be more optimistic then actual hand calculated numbers. Basically this is painting a picture of doing the same drive but seasonal conditions and temperature being the major variable to the end result. Oh and although I am in Alberta Canada, I am converting it to miles per US gallon so there is no confusion.    So winter time it gets cold here, no real surprise there and the roads can be clear at times but also often have packed rough snow or are are driving through loose snow ( they do a poor job of plowing the highways ) and yes this includes the extra idle engine time due to trying not to freeze ones butt off. 12.7 mpg is what I was getting during the winter months on average.    Then during the spring when it was around the freezing point and the highways are clear of snow, I was getting around 14.25 mpg.   Summer time, I have been getting around 15.15 on average but certainly some of the trips showed quite a bit better fuel mileage, so much depended on how much or little I had driven around town and number of engine restarts after sitting for a while at each location. But stating a best fuel mileage trip to town pretending that is what the truck gets on average is fooling ones self for sure !.      As I said in a different post, I had driven a 645 mile trip over a couple of days stint to a different destination then these other daily to town examples above, and was done during the summer with nice weather and not bucking a head wind, also keeping at 62 mph and its a rolling landscape type highway drive ( this isn't southern Alberta or Saskatchewan flat lands ) Hand calculated fuel mileage in this case though and it came out to 17.65
