Hello! I have a 2014 silverado ltz 5.3L and I want to know your opinions on the best exhaust to gain MPG. I don't want my truck to be super loud, I just want a nice low rumble, nothing obnoxious. Suggestions please?

Magnaflow is a good one. That's what I have. And it's not too loud, soft rumble at idle. No drone. Sounds amazing when you hit the gas

Finally had the tips moved to rear quarter flush and with a slight stagger.   Sent from my HTC One using Tapatalk

The number of hours spent on any given forum are directly proportional to the number of dollars spent on subject vehicle.   Ask me how I know.

The real question is, how much are you willing to spend? There are tons of great systems out there.

Most cat-back systems will have minimal increase in MPG. They are mostly ear candy with very slight HP and TQ increases.

I have the same question. Just bought the truck 2 weeks ago. I 'm new and want to know what others have put on their 5.3l crew truck.

I want something aggressive but just don't want to slap something on to make it loud and drown the engine of air.

I am extremely happy with my GMPP Borla....nice bark outside....very low mild rumble inside under acceleration. No drone!

Fit perfectly...was simple to install....

My truck is almost 2 weeks old too :)

Congrats on the truck! Did you end up removing the resonator and flapper?

The GM Borla exhaust kit comes with the flapper valve. Read thru this thread, what you are asking has already been asked numerous times, I guarantee it will answer your questions, there are a lot of good posts about different exhaust setups, the pros and cons.

Absolutely agree with this....I read this entire thread about 5 times before choosing my exhaust...I even decided against one brand because of posts here about drone and resonance issues.

 

I decided on the GM part because it has a flapper and bypass pipe the others do not. No drone or resonance so far!

You won't gain any MPG with just an exhaust. Your best hope is to just not lose any.

Its now August of 2014. Theres has to be some new information out there. I have read this thread many times. It does not go into great detail like you say.

What details are you looking for?

The GM/Borla exhaust is the only one with a flapper and bypass pipe to help with drone and resonance issues...

All other cat back systems are a crap shoot as to whether or not you will get any of theses issues. Chambered mufflers seem to be worse in this department...but that isn't in stone.

Drone and resonance are something of a personal taste nature...what your ears find pleasing or not....some don't mind it and others hate it.

So your not interested in GM Borla, Borla, Corsa, AFE, Flowmaster, Magnaflow, Flo~Pro, muffler delete, flapper delete, resonator delete, ARH headers, etc.......What are you looking for then. Catbacks are mainly just ear candy with very limited HP and TQ gains. If you want particular numbers go to the manufactures website and they are always willing to provide you with their numbers. As for MPG gains, It will be minimal, you will be lucky to see any at all.

Don't really care about gaining 2 MPG. So far I have been leaning to that Corsa Sport. Just want something aggressive. I don't care about drone. Honestly think people make a big deal over nothing. If you don't want it loud don't put it on.

Torque gains with an exhaust? Think you have me mixed up with the other poster.

Yes, I did say torque. Some manufactures claim that you will gain HP and TQ.

For example: This is what corsa says about their exhaust for the 2014 Tundra

Tips: Single Side Exit Twin 4.0" Polished Pro-Series
Sound: Sport (CLICK TO LEARN MORE)
Flow: Average of 16% gain over stock
Power Gains: Average increase of up to 3 HP and 9 TQ
Technology: CORSA's Patented RSC® Technology is designed for an AGGRESSIVE SOUND under acceleration and a DRONE-FREE EXPERIENCE during cruise. Every system is engineered specifically to each vehicle without drone while cruising.
I'm not saying I agree but Magnaflow claims TQ gains on the 2014 Silverado with this exhaust

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      Have considered installing a DC to DC charger in your camper to replace your isolator?

      Gas fill door

      Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
