Was wondering if anyone has had the Borla Atak or Type S welded in, not the full catback, on their 6.2L.  I'm guessing some of you have, and for those that have, are you happy with it?  Sound clips would also be great.

 

I'm just looking to change up the sound, so I'm not wanting to swap in a full catback.

I have on a previous generation truck. I put a Borla XR-1 3" welded in place of the stock muffler on a 5.3L Silverado and was very happy, deep tone, nice growl at WOT, no drone, and not obnoxiously loud. 

 

I can't speak from experience on the 2019+ trucks but if it was me I would swap the muffler and see how you like it. If it's still too quiet you can delete resonator down the road. Someone has to go first... right?

I have no problem going first, just figured someone had done it by now on a 2019... but looks like your right, i'll go first!

Pretty sure that you get an increased exhaust pipe diameter with the full catbacks. You go from 2.75" all the way back to 3" at least to the muffler and then 3" to the tailpipes. 

 

I do think on the 5.3L GMPE/Borla systems, it's 3" in and 2.75" out, though.

Lol well I'm not sure that many on the 2019+ Sierras, but I'm well aware I wouldn't be the first to weld in a muffler, but I assumed at least one person has welded in Borlas before I do lol

The Crate mufflers from Borla are a bit steep.

I just put the borla pro xs on my truck. It’s nice up until 60-70 then it’s a bit of droning. I love it except between that speed especially on an incline then It resonates a bit.

How is the XS when your cruising along on highway? Drone still noticeable?

When cruising fairly flat roads it’s pretty tame. Hit a hill and it’s pretty louder in the cabin. Cruising around town is great

I welded in a borla S type 3” or 3.5” in/out muffler only. Kept the resonators. Very similar to the gm performance exhaust. No drone. Can only tell that the DFM is working when your outside the truck and it’s idling away. Other than that it’s a nice deep subtle growl till you open it up

Great, what I was hoping to hear.  Prefer the sound of the S or ATAK as it seems to be louder than the XS, but was worried about cabin noise

Cabin drone is very minimal. Kinda nice with the new truck. If you removed the resonators it would sound good and a little loud but I’m sure the drone would pick up

I  was planning on just cutting out the stock muffler and flapper, leaving the resonators for warranty purposes.  I do agree would probably sound better without though.  I would simply go muffler delete but then my dealership would not honour my warranty if I did however.

      OCI, not when but why?

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences.

      Transmission jumping out of gear while driving.

      By JimCost2014 · Posted

      Probably a one and done post, but do you have a CEL on the dash? Was having issues with my transmission, fortunately only a week, and it turned out to be the transmission harness. Valve body was in good shape, so new harness with all the sensors attached, new fluid, and filter. Seems to have worked so far?

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      Two interesting tidbits of information which are NOT related were just released.   One, regarding the possible thrust bearing issues / engine failures with the 3.0. Demonworks just did a segment in which they believe they may have found "a" or "the" cause of thrust bearing failures: A missing thrust bearing. If the engine doesn't have all its thrust bearings from the factory, the missing bearing can cause extra play which ends up destroying a nearby thrust bearing which then sends metal through the engine.       Of other importance, Lake Speed Jr released some interest information regarding oil weight selection for the 3.0. Comparisons of:   AcDelco 0w20 Dexos D Mobil 1 ESP x2 0w20 Dexos D Mobil 1 ESP x2 0w30 Mobil 1 ESP x4 0w40. Mobil Delvac 5w40   Spoiler alert: The Mobils are PAO Ester -base and the ACDelco is a Group III base. Mobil shows lower wear in their tests for similar weights. Additive packages between 20-30-40 weight ESP's appear to be the same, but only 0w20 is Dexos D licensed. Wear is even more reduced with 30 and 40 weight ESP although all perform very well and resist shear and provide very similar viscosities within temperature operating ranges in the 3.0.   There are even more surprises, so just go watch it.

      Weird click noise when revving my truck?

      By JimmyB4 · Posted

      Hello Guys I'm new to the form,         I just put a 7-inch Rough Country lift on my 2016 GMC Sierra 1500 with the 5.3 and I also put a Borla exhaust on it. But I noticed when I'm in park or in neutral and then I rev my truck up really quick there is a bad click noise and I think it's coming from the motor somewhere. Anyways I got a video of it I will attach below I was just wondering if you guys think its rod knock or lifter tick or something like that because I know the AFM kind of made the lifters weak on these trucks.       Thanks!!!!!

      By KARNUT · Posted

      We’ll have to agree to disagree. I didn’t experience or know anyone who had a decent car after 100K miles in the 60s through the 80s that were daily commuter vehicles. Unless they were collector vehicles. Of course things cost more due to inflation. But we also make more money. The biggest money drains these days are things people think they need today versus what we require back in the day. Like cell phones and internet as examples. Another example is where you live. Cost of living varies from state to state. I would need twice the money to live in NJ vs Texas in retirement. The car you recently purchased was less than my first car with inflation at 3000$ in 1973. I didn’t have air, electric windows, cruise etc. Purchasing power is equivalent, you just have to do the research.
