I have the Borla dual exhaust kit (GM version) that exits straight out the rear of the truck. What I really want is the dual exit behind each wheel that comes out like the stock exhaust did. Does anybody know if I can purchase just the last piece of pipe to make it come out the sides? I have tried contacting Borla with no outcome so far. Thanks!

AFAIK, only Flowmaster has that type of option.

Wrong answer... http://www.borla.com/products/silverado_sierra_1500_catback_exhaust_stype_part__140545.html

 

They have both side exit exhaust on at least 3 different muffler systems. Now how to buy just the tail pipe section has been elusive. With that said, they all come with a million mile warranty, so they surely must have a way to get each part.

I meant only Flowmaster had multiple exit option in one single kit. I have tried before with Borla to get a piece out of a kit to no avail.

I'm sure even if I did find them Borla would charge half the price of the catback for two pieces of pipe. I really don't want to hack up a nice kit but looks like I'm gonna have to customize it how I want it

Take the Borla muffler off, get a single in, dual out Magnaflow 12388. Have a shop build two tailpipes out either side with 409. Add the stainless tips of you choice.

How much would that run you? I was checking a video of it on a ram truck and I like that sound. A low rumble. That was what I am looking for. Not imposing but still there.

At my shops we would charge you $550.00, the #12388, the labor, 2 1/4 inch 409 stainless tailpipes out either side, or out the back, all the hangers, etc. Stainless tips extra. I'm doing my new 2015 I got last week this Saturday, I'll snap some pics. I'm turning the tailpipes down in the rear corners of the truck, with the stainless tips barely exposed.

That's the look I'm going for... Dual pipes angled towards the corners. I have a 15 Denali, and the current location of my tailpipe is perfect....

I would love the pics and that would be a reasonable price for getting something I want. The Borla is too expense. I was looking for oval tips pointing out back but angled to the corner could also look cool.

 

Let me know how it goes for you

What do you do about the V4 drone? Do you leave the flapper valve?

Drone would not be the word I would use with the 24-inch Magnaflow system with two tailpipes, rather than on 3-inch tailpipe. There is a change in tone, yes, but drone refers to resonation, and there is none. On my personal rig, I turn off the AFM, so it's not an issue. However, I ran my 2013 Avalanche for 2 years with the same exhaust, (no flapper came on that year) with AFM on, and the change in tone was not an issue. I personally believe the AFM is not worth the 1, or 1.5 MPG gained when you look at the long term damage.

 

I will be removing the flapper on my 2015. I'll give you some feedback when I'm done Saturday as I will leave the AFM on for my trip home just to collect some data. I'll then turn it off using my Diablo i2.

I'm not "angling them to the corners', I'm bringing the tailpipes back high, then turning them down in the corners, roughly 60 degrees. Lots of oval tip choices out there.

Buy 2 304 mandrel bends 45s or 30s and have someone tig weld them on and swap over you tips.I built the exhaust for my 32 ford including the Corsa black box extreme mufflers for under 300 bucks. All 304 stainless and all mandrel bends. The exhaust on my 5.3L SCSB was about 350 with 3" 304 tubing, 304 mandrel bends, and a Corsa black box extreme muffler. That was also with a fabbed 3" to 4.5" radius cut tip. The exhaust on my LSX Swapped S-10 was about 400 with 3" 304 tubing, 304 bends, and a Magnaflow.

That would look just priceless. A cut and weld system on a $50k plus truck. :nonod:

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
