Here is my video of the new exhaust system I put together. MVP 3" pipe kit for the 2014-2019 sierra/silverado + 3" Flowmaster flowfx muffler + 3" band clamps

 

 

It's all 3" 409SS from cat to the tip.

Sounds great, no drone (I'm v8 only) when cruising, great roar when you get on it.

Been a month and it's gotten louder and sounds nice and deep.

Nice work man. Exhaust sound is a personal preference. So if your happy with it, enjoy the new sound!
The good thing about this setup is that you can swap mufflers being that it's a clamp on.
You just have to use an offset inlet/center outlet muffler

Pretty sure MVP is in the US unless you can prove me wrong?
It's working great and improved throttle response but you don't have to go this route [emoji2369]

3" is fine for a 5.3. General rule of thumb is 1" for every 100hp. 

MVP is US company, that doesn't mean they don't outsource their pipes from China, either way who gives a ******. 

 

Just keep an eye on the pipes, 409 is a lower grade stainless, it will rust eventually.

I hope it is made here, and MVP is not just importing cheap speed parts from Asia.. i'm tired or seeing those cheapo headers killing local speed shop manufactuers. its a sin to buy stuff like this durring these times!

Lol, the 5.3 comes stock with 3inch. Don't you have a 5.3?

 

*Edit*

 

My mistake, stock is 2.75?

do a dyno run before and after
Nahh, for a 1/4 inch difference not worth it.
I'm just posting this here to give another option for those who just delete muffler or chop stock setup to make something worth.

This is cheaper but great quality for what it is. One could spend double the price for a Gibson or 5x more for Birla [emoji2369]

you can use the TRACK ADDICT app with HPT bluetooth obd tool to get a before and after virtual dyno run or 1/4 mile run to see what you lost or gained in terms of torque or HP

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
