Most CatBack systems don't require any welding and are pretty straight forward. Can be done at home no problem.

I have installed Borla and Corsa kits other than taking up some of your time, the work is fairly easy.

 

Edit: a lift would be nice but is not required on most 4x4 trucks. If you can slide under the truck and don't mind crawling around on the ground, it's gravy train.

 

Edit: you may not be able to get your factory exhaust out without cutting it somewhere, with a lift it's a bit tricky but you can get it out all in one piece. Most people cut it somewhere anyway just to get it out easier.

Make sure you have a large piece of cardboard or something to put the muffler and other components on, helps to get them under the truck easier.

Borla GMPP dual out the back ordered and should be ready to pickup by tomorrow afternoon!

Decided to go with GM system. More comfortable with installing a part with a GM parts number on my brand new truck...after warranty expires I will consider changing the muffler/removing the AFM flapper and doing a tune.

Both..

 

That flare in the aFe pipe is where I cut it and added the different tip. The aFe tip in the kit is 3.5 in and 4.5 out... ok for a diesel, not a 5.3L IMO.

You have a pic of the new tip? I agree the provided one is wayyyy to big.

Exhaust is installed!

How's the sound? I want the GM Borla but tow quite a bit and don't want to aggressive/sound. I understand its the touring muffler not the sport correct?

Yes touring muffler...

Sound is quite subdued...

I am sure it will get a bit more aggressive as it runs in over a few weeks.

Still very quiet inside...nice bark under hard acceleration, but still not boy racer loud.

So far sounds just like the videos Borla has posted for the GM systems.

 

Took about 1.5 hours total for install, doing it solo...

Took most of the time getting the truck up high enough to get the stocker out in one piece. :)

 

Will be towing our 7,000#+ travel trailer up to south Lake Tahoe next week, so we will see how it goes.

Awesome thanks for the info. I had a Borla touring muffler on my 2011 and it was a little loud while towing but that was on a 5.3 with 3.42 gearing. My 6.2 has 3.73 and can stay in 5th longer. The 5.3 had to go down to 3rd at times and the noise got old while towing. Please report back after your trip I tow a 5500# TT as well.

I ran dual pipes to a x pipe than to a di/do 40 series flowmaster.. Sounds better than any of those catback systems I've heard in person and on the internet. Absolutely zero drone. Loud when you want it to be and mild while idling. My dic is showing 1 mpg increase.. My truck feels more snappier. It was a noticeable difference. .

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?

      “Service Emission System” & “175 miles until “65 MPH Max Speed”

      By ManyCamaroz · Posted

      I don't drive this truck on a regular basis since I have a new company truck with no out of pocket fuel or maintenance cost. Yesterday I got it out to run some errands and got the title message on my DCI. A quick Google search suggested to first clean the Map Sensor. I pulled it out and it was sooty so cleaned it up and reinstalled it. Issue not resolved. My OBDII is a couple years old so didn't see any codes. Today I took it to a friend at AutoZone to get him to check it with his reader. It had the following codes: P20C3 P02BB P221F Stating the most likely solution is to replace diesel emission fluid (DEF) tank assembly.   So, I guess a trip to the dealer is necessary. I read where there was a backorder on these tank assemblies several years ago so hope that has been resolved.

      Do you keep your tires at full capacity? 80psi

      By Chuck FB · Posted

      Are you using a weight distribution hitch system with your trailer as that alone can change the actual tire pressure requirements needed. It would prove interesting to see what the actual individual axle weights are on your truck when you are hooked up to the trailer. In fact when your hooked to the trailer, typically if anything unless it has a large capacity weight distribution system that is over cranked, often the weight on the front axle will be less when hooked up vs driving empty and certainly if one doesn't have a weight distribution hitch. Really the only times one may get up there with weight on the steer axle is if there was a snow plow mounted on the front or a motorcycle on a rack or with a very large jockey tank full of fuel at the front of the box that transfers a bit of its weight to the front axle.    And of course your tires carry more weight for a given tire pressure due to their size vs a stock sized tire so there is that to take into the equation as well.

      Great info here thank you. I just joined, we have a 2014 Silverado truck we bought about 4 years ago with less than 5,000 miles on it. It has approximately 24,000 on it now. It appears to have all the standard issues that people are talking about. Occasional charging problems especially using 110 volt, occasional blinking triangle where nothing will turn on when first starting the truck but it will reset itself if you wait 10 to 15 minutes. Noisy coupler between the flywheel and the generator. Our truck is speed limited to 74 mph, is there any way to change that? The latest issue we have been dealing with is when driving long distance on the highway at full speed the generator does not keep the batteries charged. The meter will go into the yellow/red border Zone for charge status and the yellow triangle will illuminate solid but the generator will not keep the battery charged, not sure why the controller doesn't tell the gas engine to increase RPM to increase generator output it usually stays well below 25 kilowatts even though the battery is discharging and I have to slow down the highway to 45 mph and eventually pull over and let the truck idle to charge the battery so I can continue driving at speed. Has anyone had this issue before or have any idea how to diagnosed it? When via Motors was around it they were very helpful at troubleshooting. This becomes much if the Terrain is hilly and you're towing a small trailer

      Tonneau cover that does not leak water

      By Z45 · Posted

      I have the GMC accessory (REV) cover installed by dealer. Ordered with the truck.  They did a very good install job, can't find a single issue. Some water gets in around the tailgate but no where else.  You can see daylight around the tailgate but that's not the covers fault.  Installation is means everything. Guys at my dealer were seasoned pros, not inexperienced here today good tomorrow types, like many dealers employ for these jobs.   I don't mind paying for a professional job.

      Like others have said, they will all leak. Mainly at the corners.   I have owned several and the best has been my current one. Revolver x4
