Man, I'm with you on that squashed crossover pipe! I mentioned replacing it with a true round section and got SO MUCH HATE in another forum here. The first time I saw that squashed pipe I thought it was a joke. Post up your findings when you get around to it.

Probably because everyone thinks if the OEM does it then it has to be the right thing to do.  I plan to have an oval fabricated properly or like you said put a round tube in but lower it a bit away from the trans pan and wrap it with header wrap to hold in the heat.  Cost always overrides quality in mass production.  Most folks don't care and don't know any better.

It’s been tested through and through,  showed no loss what so ever. Do a search was a very detailed thread about it. 
conclusion is your wasting your money.

Tested with what, a computer simulation, a flow machine, a chassis dyno, someone's accelerator pedal feel.  The major difference between custom builds and OEM builds is that most of us will spend money to do it correctly.  When I cut mine off I will measure the squashed tube and calculate the volume and CFM and compare it to the round tube.  This is simply for my personal satisfaction.

Just swap the muffler. Waste of money getting a cat-back in my opinion. Cut out the flappers and replace muffler. It already has 3.5" pipe split to duals. Catback is just basically replacing good pipe. 

Does Borla offer just the muffler that will fit?

 

Im leaning towords the S series sound.

 

If I can get just the muffler....Done and done!

Yes, Any exhaust shop will be able to fit just the muffler. Cut out the flappers and weld in the new muffler, they will have to fab a little extra pipe due to shorter muffler.

 

These trucks come with larger diameter pipe  which is free flowing unlike from years past where more benefits were had from full cat back system. The restriction is in the muffler and flapper valves and is where the gains will be had.

Dual Borla for sierra with oem side exit?

Unfortunately, we do not have a split rear system for the trucks with the side exit from factory. Sorry about that.

Hey Ian,

Love the sound of the S-Type. I have a 2020 5.3L Silverado Custom Trail Boss. Would the " Silverado/ Sierra 1500 2019 Cat-Back™ Exhaust S-Type part # 140770CF " fit on the 2020 models without any other modifications? I didn't see anything on the website about 2020 models. Thanks!

Hi Andrew. Yes, the systems do carry over to the 2020 model year and would not require any modifications to install. We will be updating it to show that. If you do plan to purchase a system, we recommend ordering from our distributors as they will have the better deal with free shipping in the U.S.

I just installed the S type this morning on my 2020 AT4 6.2. I did it all in my garage without jacking it. I only needed to cut the factory exhaust right behind the muffler. The new system went in very easily. 

Overall. Super easy job and only took 2 hours with no assistance. I love the sound and am very happy I got the truck without the factory performance exhaust and just purchased it myself.

Ian, if I wanted the S-type sound with only a muffler swap what would I buy?

 

This is for a 2020 AT4 truck with the 6.2.

Wanted to share, as I had a hard time finding comparisons for the new 2019/2020 Silverados.  I was going back and fourth between touring and s-type, leaning more towards the touring, until I listened to the videos in my truck, with its sound system.  Computer speakers and cell phone speakers just don't do it justice.... need to get those bass tones.  Super glad I went with the s-type, it's loudest at a could start, low/soft growl with driving in lower gears around town/in neighborhood, at highway speeds you can't really tell it's there, until you press on the gas to accelerate or pass someone.  I'm in my late 30's and didn't want to go all high school on the exhaust, but super happy I went with the s-type the deep tones are nice and rich, and should really mellow out over time, and it's not obnoxiously loud.  And absolutely zero drone at highway speeds.

For it’s worth I put a quad tip Borla S Type on my 2019 6.2 liter Chevy Silverado and I absolutely love it.  I had the weakest model on my 17 Chevy and it just wasn’t enough when your spending that kind of money.  I tried posting a video of sound and look but it says file is too big.  If anybody wants to see and hear it email me at [email protected] and I’ll send the video right over

    • I have changed oil and filter for years by starting a cold engine to warm oil up, let it run 5-10 minutes depending on temperature. Drain until it starts dripping, refill with quantity from owners manual or get it close.   
    • I changed the factory fill oil in the rear diff of my truck for the first time today and the miles is close to 9000 on the truck. There was a lot of fines on the magnet, a very thick layer but working it through my fingers it all felt like mush and as most know it appears like graphite, so no surprise chunks anyway. Certainly was time to do it from my thinking and could have been done sooner but the oil didn't look awful but sure wasn't new looking and never expected it to either. I did use some solvent to help me clean out the bottom area of the axle housing, just get any other stuff settled at the bottom washed and wiped out of the housing for the bit of effort it takes. I used Amsoil Severe Gear 75W90 in the easy packs to try out what they are like and I used up 4 packs and didn't spill much at all in the process but did take all four of the packs and go to the work bench and emptied them into a measuring container and there certainly was some in them that added up to something, then poured that into one of the easy packs and squirted in what I could get out of it. I would say the level is within 1/8th of an inch of being level with the threads at the fill plug so just the perfect amount. Once again, more than what GM says the fill volume is but computes with what others are adding to their rear diffs as well. 
    • So speaking of oil consumption with my L8T as I just changed the oil yesterday and made the switch over to Amsoil SS 0W-40 from the Mobil 1  5W-30 Truck and SUV I just dropped out. 2900 miles on that oil as well as  68 hours on that oil ( so used to equipment with an hour meter and that becomes valuable information to compare with others as well ). Once again the oil use was so very little, I am going to say it dropped under 1/16 of an inch on the dipstick. No towing was done and this interval was from early spring until now.    One interesting item to note is that going by the 5 quart jugs I was using before from Mobil, it was showing that I was putting in 8 US quarts to bring it to full if not slightly over the full mark according to their jug markings. Granted I did allow more drain time this time and in part because the engine oil was only lukewarm as I started it and let it idle and not for long enough to get the oil itself hot ( the engine was up to operating temp ). The oil in that state just seemed to take forever for it to drip out but not only at the drain plug but at the oil filter housing as well, perhaps I had never quite gotten all the oil out before and I could have still waited longer but as it was I waited well over 3 hours. I think next time if I have the time I will do an experiment by dropping the oil and lets say leave the pan under it for 15 minutes, then switch to another pail and let it drip out overnight and measure how much more oil comes out. So this time and yes I ended up getting it just over the full mark as I was experimenting with trying to get the level to the add mark after I had run it and then waited some and then added a bit and waited for a certain amount of time for it to settle to the add mark. I very well may not have waited long enough for that experiment but I got to the add mark, then dumped in a full quart and waited some and checked and then waited some more and it crept up more ... and then finally oops, it was slightly over full some hours later when it really had settled all it would. I find this engine sure takes time for the last bit of oil that gets poured in to finally make its way into the crank case. I can only guess at how much too much I added as per maybe a 1/10th of a quart. I had poured in 8.5 quarts going by the quart containers as per 8 quarts and 16 us ounces. I was shocked at how much this was off compared to the prior oil changes and if those larger jugs and they are not marked accurately enough or they contain slightly more than what they say, or the drain time factor made that much of a difference. But I know on this forum there have been others who have said they have put well over 8 quarts in their L8T and now I have also going by the Amsoil true quart containers. Its a confusing convoluted mess up here in Canada with some oil manufactures packaging is in true US quarts, some is also in true US quarts containers on an even number of quarts but also marked in liters which becomes the odd ball volume of a fractional amount of liters. Then there is the Liters only containers, no US markings as its a true metric container and only measured in Liters to an even number of Liters. But remember we used to have Imperial Gallons and Imperial quarts as well !. 
    • Holy smokes. Clearly not a deal on that truck. I just mean in general, matte or painted trim is becoming more normative than chrome, but I know the Black Optics packages on various vehicles are being sold as uplevel trims. They look really good, but sheesh. It's just paint and plastic.
