Hello all.  The GM Performance systems for the 2019 Silverados are indeed made by Borla. They are made according to GM's specifications and are separate from the aftermarket Borla systems.

I found two different part numbers for the S type 140773 and 140778 whats the difference in sound? I have a 2019 HC crew cab short bed with 6.2

140778 is the true dual exhaust (single muffler) for the 6.2L.  2 pipes in / 2pipes out.

 

I'd definitely go with that one.  Much better setup than a single in/dual out... Wish they made it for the 5.3L.

Is there any actual performance difference though?

Is there any real performance difference with the regular Borla single in/dual out over stock exhaust; i.e. GM's "performance exhaust"?

 

If there are gains to be had with a bolt on exhaust (no long tube headers), besides a nice growl and your butt dyno, then it's even more true for a true dual exhaust.

There is and it's been posted in a multitude of places. Is it huge? no, but it's noticeable.

 

I shouldn't been more clear and the reason for my ask. The dual in / dual out has no tips and uses the factory valances...boring. It doesn't appear Borla makes a quad tip setup like the single in / dual out packages to add on to this dual in / dual out package. So I'm weighing the difference between HP/TQ adds between the two packages vs the appearances.

Aaahhh that makes more sense... Well that's stupid they don't offer their dual exhaust with different tips, since it's their best one.  I do love the carbon fiber tips, that's the one I got.

 

I'd call them tomorrow and ask to speak to someone in their technical department, and see if adding the tips you like would be possible to the dual exhaust.

I installed the gm performance exhaust and the factory air induction in my 2019 Denali with the6.2. It was a little louder than what I wanted on a denali so I had a cherry bomb put on each pipe just before the tips. It toned it down but sounds better than the stock exhaust.At 70mph Ivan get almost 26 mph. Get up above 75 and it drops back to around 19-20. also installed a Peddle Commander and absolutely love it. It makes throttle response unbelievable. I want to get the truck dynoed but my guys say they haven’t come out with a way to hack the computer. They have guys lined up waiting on super chargers but have no way to tune them

Not trying to sound like a ass, but your "guy" needs to keep up to date for his customers.

 

 

HP Tuners released their tune a couple weeks ago.  First ones to crack the ECM.  Only thing is, you have to do a ECM swap, and then buy the credits and software, and have a custom tune done... Say around $3K.

 

Also, warranty is definitely going buh bye with this...

i've talked to Borla and posted about the duals before. I'm not sure what "mods" would be suggested where true duals gain more than the 1-2. I assume more than just a CAI. 

 

There is not much in the way of performance gains on a stock vehicle over our regular system, the true dual is geared towards increased potential for vehicles that have further modifications than stock. The sound quality on a single vs true dual is not different. An S-type sounds like an S-type etc.

Don’t want to do a swap. Haven’t talked to them in a few weeks. They are a high performance racing shop and trust what they tell me. This will be the 3rd truck that they will tune for me.

Sounds good.  What part of the country are you in?  I'm in Houston and supposedly Houston House of Power did the first full custom tune on one this past week.

 

Anyway, unfortunately a ECM swap is typically the only way a tune can be performed on these vehicles now days.  I wouldn't do it myself, definitely take it into a shop to have them do it, and then tune it.

 

More info. can be found in this thread about tuning as well:

North Carolina. RPM Motorsports handles my mods. Been happy with them so far. Truck performs really well, would like to get the top end limiter removed, the rest I can deal with for now

Has anyone messed with the flappers at all? I’m just doing a muffler swap this week but I’m absolutely lost when it comes to the flappers. I want as much noise as I can get without droning at highway speed or too much noise at cruise. I got a Magnaflow 11229 muffler. Question is, do I cut both flappers off or only one? If one, which one? I’m thinking the upstream flapper will kill more drone than the downstream. I read on another post that both flappers removes makes too much drone

Check out the following part numbers.  Borla offers all their tip options with the dual system.  

 

PNs 140778, 140779BC, 140779CF, 140785

 

 

I’m looking at the true dual systems too but can’t find any sound clips so or comments regarding sound with DFM so am a bit hestitant.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Progress... sort of.   Intake is disassembled, spider is out, fuel lines removed. Used a torch on the stripped screw with the lower intake off, much easier when I've got the intake sitting on my workbench, I made it talk. Walked right out with a pair of vice grips once it was nice and toasty hot.   New parts are piling up on my service cart waiting to be installed. Distributor, temperature sensor, new gaskets, fuel line kit, themostat, water neck.   My new pickle is I don't want to spend $600 on a replacement spider. I'm not sure IT is bad. I'm probably splitting hairs. Or it's $300 to send mine away and another 3 weeks of the truck just sitting. I have half a mind to assemble everything with the old spider to see if I can get away with just replacing the fuel pressure regulator to be safe. The obvious issue was the gushing high pressure fuel line which will be replaced. Getting to the spider really isn't that hard, and now I know what I'm doing , swapping it would be a breeze should it absolutely need one. Stupid, or smart?   The part that gives me pause is replacing the distributor. Well, it's already out. And I didn't mark it, whoopsie! Engine was at TDC when I removed it, I know that, so upon correct reinstall the metal tip on the rotor should point to the TDC mark on the distributor because that's where it was pointing on the old distributor. Worst case I'm a tooth off and have to re-stab it.   But then, what? I assume the truck will start. It doesn't appear the timing can be set. Here's the problem: These distributors can't be rotated but a degree or two, by design. What I read is Cam ****** needs to be -2 to +2 degrees, ideally at 0 (and checked/set above 1000 rpm). There should be enough wiggle to get that properly set, but checking the reported value is another potential issue. My Actron 9185 scanner says it supports enhanced GM PIDs and Cam ****** is one of them but it's unclear that I'll be able to correctly see it over OBD 1.5. I can see why people end up junking these things with life left in them. They're an absolute nightmare with tweener-year diagnostics/electronics and unobtanium parts.   Fingers crossed it starts and idles nicely. There can be hope, right? I'ma buy a lottery ticket the same day just in case.   Next steps..DO IT. I have not installed an intake before so I've been reading and watching a lot. Some say NO RTV except on china walls, some say DO RTV on water ports but not fuel/air intake. 1/4 or 3/8 bead on China walls? I think my strategy will be, obviously, RTV china walls with overlap on the gasket corners. Chapstick-style RTV the water ports. Leave intake ports dry. The only set of intake gaskets I could find locally are Edelbrock performance gaskets (uh...for an asthmatic 190hp V6? LOL) so we'll see how they do.   #NoToolLeftBehind. It took an hour, but my recovery mission for my deep 10mm socket was successful. It had rolled down the bellhousing and wedged itself between what I think are the fuel lines? I couldn't see it at all, but with a junk antenna I had laying around, I blindly went poking/sweeping for it, heard it clink, raised the truck, and caught a sliver glimpse of chrome with a flashlight way up there in Narnia. I had pushed it farther along the lines holding it captive, but within access of severely improvised tools, poking and cursing at it to finally knock it free to where I could get a fingertip on it to bring it home.    Not much to see.
