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

Not bad at all really. Hardest part was getting the old stuff out. I had a little interference with the driver side primary and the frame but a quick y pipe adjustment took care of it. I’m actually pretty happy with the TSPs.

I just installed some Texas Speed longtubes with catted Y pipe and a Blackwidow Venom 250. Little bit on the raspy side and I’m pretty sure the cold starts wake the dead. I’m sure my neighbors are happy. I’m going to put a AFe resonator in front of the muffler to tone in down a touch.

That sounds beautiful. How much did the whole setup run you? I'm running a venom 250 as well, minus headers and y pipe

The Venom 250 sounded good with manifolds but it is way to airy and raspy with long tubes. I switched it out with a Borla XR-1 and it’s much better. I got the headers brand new from another forum member. I probably have less than $800 in the whole system. Headers/Y pipe and 2 different mufflers.

Hi all!!  I'm the new guy on the block.  I read thru most of this thread and noticed that a lot of people prefer to buy an exhaust that minimizes/eliminates the V4 drone instead of tuning it out.  Is that for warranty purposes or is there another reason that people don't wanna go the tuning route?

 

I currently have a Dodge Ram but will be trading it in very soon for a 2016 Sierra SLT.  I'm putting together my mod list for the truck and am wading thru exhaust options.  I like a nice, aggressive rumble so I'm definitely thinking that I'll go with some Texas Speed longtubes with the catted Y pipe.  Not entirely sure what I'm gonna go with for the catback yet tho.  I'm planning on tuning out the V4 (as I did on my Ram).

The ram v4 sounds way better and is very tolerable compared to the Chevy. The"pulse" is quicker. The 5.3 sounds like those guys in a marching band with the big drums behind you. If it sounded like the ram... I bet most wouldn't complain.

Interesting.  I didn't know that it was so much more pronounced in the 5.3.  In my mind, that would be even more reason to just tune it out.  Why don't more folks do that?

I'd say it's the chance of voiding warranty that many dont tune it out

That’s one of the reasons I’m buying a Superchips tuner before I do my exhaust. That way I can tune the AFM off and save the stock tune if I need to put it back.

Yep!  That's my plan as well.

GM keeps a flash count on the ECM. Even if you put the stock tune back, they'll still be able to see that it was tuned. Just a heads up

Yeap... The 2014+ (Or any of the new LT engine computer is basically a "black box"... it saves the times it has been flashed, and which parameters were changed.

Picture attached explains it, basically an adjustable closed end pipe that keeps the drone out with magic haha but it really does work you adjust it based on your final gear Rpm/speed on the freeway and adjust it till you hear little to no drone, mine came pre adjusted with the kit

This works... I had done a few now, but all the ones I have done are dual exhaust, so I don't know the formula for a single pipe. The formula for my Silverado gave me a tube thats between 28-32" long for each bank, and that's for an RPM range from 1800 (for the 28) and 1600 for the 32). I am changing the mufflers and the routing on my exhaust so once I am done I will see if the drone changes in RPM's before I make them.

      2021 suburban RST - acting up/lights flickering

      By 520Zilla · Posted

      Hi all,   I just bought a 2021 suburban RST with 88,000 miles on it and everything has been good but I’ve been noticing within the last month or so that there are small electrical things going on and I know what the AGM batteries and all the electric electrical in these big trucks you need to have a constant flow with good voltage   That being said, I bought a new battery thinking that that might have something to do with it but today I went to get in and start it and it said no key found when I had the key right in my pocket   It also proceeded to flash the lights inside and outside for over 30 minutes as I went to disconnect the battery as soon as I touch the negative terminal, I heard the relay reset and everything come back up. I got in the truck and started it no problem.   Anyone else have this happen to them? I’m starting to think it’s the KARR system that the dealer installed short circuit stuff.

      “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.
