2016 GMC Sierra 1500 Exhaust


Recommended Posts

Posted

This forum was extremely helpful with my floor mats! Now I'm beginning research on after market exhaust. Before I get too far along in my search....how would modifying my exhaust affect my warranties? Any suggestions at all? I don't want anything obnoxious. I just want it to sound "nice" when it starts up. Just slightly more than factory.

I went with the borla gmpp sport muffler and cut off my resonator. Sounds perfect to me. Not loud, but sounds great at startup and when you get on it. No drone on the expressway either.

I went with Corsa. Love it,but may not be for everyone. Dont worry about the warranty. A little drone,but not annoying imo. Sounds amazing on a cold start. Barely noticable on the highway.Not obnoxious to me anyway. Nice crisp sound.The above post seems to be a popular choice as well. GM approved. So no warranty issue.

I also went with the corsa. Brownsfanhere pretty much nailed the description. It does have a little drone, but it's not bad. Pretty sure it's only when it hits v4 mode. I haven't heard the GM Borla in person, but I think its quieter than the corsa from the videos I've seen online. That's why I went with the corsa. I wanted a more aggressive exhaust. Dealer says the exhaust won't void the warranty. I've had exhaust on all my vehicles and I've never had a issue with a warranty because of it.

You could just cut out the muffler and keep the resonator, flapper valve, etc. This will give you a little deeper sound but not obnoxious. Leaving all the other components will help prevent the "crappy sound" everyone complains about with the V4 mode on an aftermarket exhaust system. Here is a link to a video of a 2014 5.3L with just the muffler delete:

Count my vote for the Corsa as well. Take it from someone that's ran Flowmasters on all previously owned trucks. I absolutely love my Corsa setup, and even with long tube headers, it's quiet on the highway (I have AFM deleted so almost 0 drone at all). When you get on it you'll think you're in a car. If for some reason you decide against Corsa, I also highly recommend Borla.

1) Any exhaust should not effect your warranty except on those parts you replaced obviously. It would be up to GM to prove the exhaust ruined something which is so highly improbable it borders on impossible. I guess if you were choking/restricting the engine but you would be opening it up so physics wise it will do no harm.

 

2) You will find as many opinions as replies when it comes to aftermarket exhaust. I personally would not recommend the Borla's and instead say go with Flowmaster but that is only an opinion since they both do the same thing in essense. What I really recommend is sitting down with some decent speakers and checking out various videos of the different options and deciding what you think sounds best to you.

 

3) IMO The only real difference is in the true dual set ups vs. a single pipe into 2 set up which is very common. True dual will cost more.

Id start with muffler delete some like some don't. Not really loud cursing nice burble starting up. Any muffler you add will make it quieter. Full new exhusts is a waste performance wise even stock they flow enough.

Service manager at Beaman GMC in Nashville was adamant that an aftermarket exhaust would void my warranty. I even brought up to him that the only mods would be after the cats and in no way would harm the engine. He still, rudely insisted that it would void the warranty. I guess it just depends on the service dept you're dealing with? Not sure. I completely agree with you, but just sharing what I was told not even a week ago.

    • I just can't think of the exact term GM uses for that higher gvw package without looking at the website but basically sort of a trailering package and I imagine it may also have been created to skirt around the licensing fee differences between a3/4 and 1 ton that apply in some states although ironically I believe in some states its the reverse that a 1 ton is the cheaper truck to license over a 3/4 ton. It makes no difference here in Alberta but oddly enough a 1 ton through my insurance company is a bit cheaper to insure over a 3/4 ton as its based on the insurance statistics they generate.    For sure when ever you do have the chance to weigh your truck and to be fair, try to have the fuel tank full or nearly so rather than give yourself a false sense of the truck being lighter by having an almost empty tank.    In my other comment I was mentioning stock sized tires and partly in case someone was reading this and thinking they could lower their pressure down to what your aftermarket tires are able to do with your empty truck as that is a vastly different picture in the leeway you have to play with for running minimum pressures while remaining safe. I will say also that its easy to see from reactions of truck owners that may have been more used to owning a half ton in the past or a car and be it on a forum like this or in person etc that they get so wrapped up in that placard pressure sticker that they can't get their head wrapped around the fact that an HD truck due to how much it can carry can also vary the tire pressures drastically lower than those pressures ( typically more so for the rear axle on stock sized tires ) when empty vs some car that isn't made to carry much so the tire pressures can't be lowered since it needs almost that much pressure just to carry the empty car.    If I ever do find myself in the states with this truck, I will only be too happy to switch it over to the US measuring system as then I will understand all the dash readings. The only thing that is off for me slightly with US measurements is US miles per gallon as I grew up with the Imperial gallon and to this day up here anyway speak in Imperial miles per gallon ( I don't do that on this forum though as that would confuse everyone for no good reason ). 
    • Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol    
    • You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !
    • This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.  
    • My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page
