Alright, before you say you don’t hear anything let me explain first. This video posted below is my 2021 Trail Boss 3500k miles and has the most annoying exhaust sound. I know there’s some serious pro’s on here who could tell me what’s going on.
Essentially any time I start it up high RPM, accelerate, or decrease RPM’s I’m greeted with this annoying metallic rattling noise coming from exhaust.
Took it to dealer who claims it’s normal (per-usual) and says it’s the liters I can hear in the exhaust tone. They checked exhaust donuts and heat shields and found no issue.
However you can hear a rattle and what sounds like an exhaust leak. Was told it’s a flapper but it’s not, flapper is toward back passenger side. This is front passenger side.
I could best describe it as escaping air coming from somewhere near the manifold I’d assume. Almost like a metallic farting exhaust noise for lack of better description.
Videos to follow of noise while commuting.
So i finally pulled the trigger and installed a light bar on my 2019 Trailboss. I wanted a bumper mount, but refused to drill holes. SoAfter looking all over ZROADZ was the only mounting option i could find.
So I bought these ZROADZ mounts
https://zroadz.com/i-23909931-2019-2021-chevrolet-silverado-1500-front-bumper-top-led-bracket-to-mount-30-inch-curved-led-light-bar-pn-z322282.html#!submodel%3DLT TRAIL BOSS||model%3DSILVERADO 1500||make%3DCHEVROLET||year%3D2019
and this Rough Country 30” Curved bar light.
The install for the mounts and light was very easy. the ZROADZ link above has a pdf with installation instructions, but it mounts to the bumper mounting bolts. The Rough Country light bar has a very high quality wiring harness and i didn’t want to mess with that and shorten it up, so the excess is taped and hidden behind the fender. There is an accessory “port” where the trucks wiring goes through the firewall, so getting wires through was a cake walk. Just cut the end of the rubber piece off. I took the switch plug aport pushed it through and put plug back on. There is a black plastic mounting box for one of the vehicle control modules you will have to remove to reach the wire on the inside. It is held on with two nuts and comes off easily. I ran the switch wiring behind the console and up through steering column. Its a temporary location until i can find a good solution. I would really like to use one of the blanks in the center console. The light bar itself is crazy bright and can’t believe i went this long without it.
My only complaint and its me being picky, is that the light bar sticks out a bit further that i had hoped. And that is only because the RC light bar is no where near as deep as others i have seen. Its about an inch shallower than the light bars on my ATV. If it was like other light bars, you probably wouldn’t even notice.
I wanted to post a bunch of images to show the install, but it only allows a few so here is a link to a google photos album.
I hope this helps, if anyone has a questions or wants other pics. Let me know.
Around 15K I had the transmission issue with it slipping and the dealership replaced the fluid with the mobile 1 which seem to resolve it enough that i could live with. The transmissions still clunks into first when down shifting but whatever. Well now at 30K I have something similar going on, but seems just slightly different. When I'm cruising around 35-40 it almost feels like the truck is braking or downshifting and then speeding up, but enough everyone in the truck can feel it. At first i was thinking it was the DFM kicking in and its opening and closing valves so i bought a pulsar box ( i needed it for tires and autostop/start as well) and disabled the dfm, but it still does this weird shimmy. I know that doesnt necessarily still mean its not dfm but... still.
This may sound crazy, but its much worse when its really hot outside and the truck has been sitting for bit. This morning it was cloudy and about 80 degrees. Didn't notice it too bad when i left, but this afternoon it was about 95 (truck had been sitting in the sun for several hours) and when i went to leave even the passenger was thinking i was about to run out of gas once we leveled out around 40. After stopping and going a few times it settles down enough that its back to just being very subtle, but still noticeable.
Is anyone else experiencing something similar? Is it DFM, Torque converter, transmission or just something i will have to trade out to resolve.
I appreciate any answers that are offered up because i really, really don't want to get rid of this truck.
Welcome to my build!
Started with a 2019 Silverado 1500 LTZ 4wd 5.3L, which I bought with 9k miles on her in August of 2020. Got a crazy good deal on it, justified me driving to Georgia from Houston to pick it up. It even came with the Ranch Hand front bumper on it already, other than that she was stock.
Little bit of background on my past trucks, I've been fortunate to own quite a few: 07 JK Wrangler, 08 Silverado 1500 LT Z71, 2014 GMC Sierra 1500 SLT Z71, 2015 GMC Sierra 1500 SLT w/ 6.2L, 2016 Denali 2500 Duramax, 2017 Silverado 1500 LTZ Z71, and finally my 2019 Silverado 1500 LTZ Z71. I also have my 2015 ZL1 Camaro for a little bit of fun on the side, my wife has gone off to German side and is rocking her Porsche Cayenne.
So here's the current list of mods:
4" Zone Lift kit w/ Fox rear shocks 35x11.50's Nitto Terra Grapplers on stock 20's Front and back Ranch Hand bumpers Hooker Blackheart Cat-back exhaust utilizing factory dual tips K&N Series 63 cold air intake Rough Country Automatic drop down steps Camlocker Tool box Front windows tinted to match back factory tint Front windshield tint strip Chevy All-Weather floor liners Stubby antenna
Just went on a shopping spree of sorts and this is what I've got on order:
Boost auto parts auto fog mod Putco Blade LED Tailgate Light Bar w/ Putco wiring harness All LED bulbs; replacing turn signals, license plate lights, and reverse lights. And the GRAND finale, King 2.5 PRS coilovers
The list of things to come in the near future:
High Country cluster from White Audio and Media, had their Tahoe cluster in my 2017 and it was fantastic! Waiting to order the rear King Resi PRS shocks until my checkbook bounces back a little bit. Lol Going to be putting on several LED light bars and maybe a pod or two, going to do my best to blend them into the Ranch Hands and make them as non conspicuous as possible. I'm strongly considering doing a Dyno tune w/ Kooks long tubes as well. Going to be doing ceramic tint all the way around. Limo on back windows and back glass, 15% on front windows, and 35% on the front windshield. I've got a drop in plastic bed liner that drives me crazy, so I'll more than likely go ahead and get the bed sprayed.
Things I'm considering:
Looking into changing up the rims and trying to clear 37's when the time comes for new tires. Blacking out the badges? Still not sold on this one... Turbo or a supercharger kit? This one would be way down the line though. Anything else that catches my attention, let me know if you can come up with anything!
Here is the truck from stock:
Are you Looking to change your headlights and grille on your custom Silverado to the LED HID / signature curtain daytime running lights that High Country’s come with and the bow tie grille ?
Here’s how I did this to my Custom Trailboss ... how to video. Videos nothing special but it’ll give you the pics with notes /video clips that I took so you can convert yours over if your wanting to . Back when I did this conversion I couldn’t find anything online that really shows how you do this so hopefully this helps the next person do this . Takes about 3-4 hours
cost is about $3k for all new oem parts . I got my headlights , wire harness through Gen5DIY.com $2400 and the bow tie grille $580 through gm parts warehouse. Both are great companies I’d fully recommend that made the process really easy .
I’ll list the part numbers too if you wanna research and look for some lower prices if wanna go with used parts or shop around if you wanna that route but don’t forget you’ll still need the headlight harness which is about $250 from Gen5DIY to make all the lights work properly . After you sell your used Custom headlights and grille parts from the conversion you can get back about 1k dropping the cost involved about 2k with new parts.
May ask why not just buy the LT trail boss ., well here’s why I did not .. when I researched this is what I found .,
My Red Custom trail boss came with the halogen lights and the LT Trailboss has the better looking lights that are LED (not too bright though but have a good look to them still) but they are not HID LED which are way brighter unless you buy the midnight black edition trail boss or the high country which #1 I wanted the red trail boss not black , # 2 I wanted HID LED lights not just the LED lights , so I made my own custom set up for a small cost compared to getting a midnight edition Trailboss or high country
