This weekend I'm planning on installing my Gibson dual exhaust system on my 2014 GMC Sierra 1500 Crew Cab Short Bed All Terrain 5.3L. I wondering if I will actually have to cut my stock exhaust for installation? Has anyone done this?

I think he's asking if you have to cut the factory exhaust to pull it out from under the truck.

 

I've heard mixed reports. Some say it can be removed without cutting, some say no. I think your chances are better if you are able to jack the truck up a bit. The hard part will be getting it over the rear axle.

No cutting if you're using a lift. Otherwise, it depends on how high you can get the truck off the ground.

I'm asking it the factory exhaust is bolted together a the location where the new cat back exhaust is intended to bolt onto the factory exhaust? Thanks

Can the stock exhaust be removed without any cutting once it has been disconnected from the 3rd Cat? I was planning on not even jacking the truck up to change the exhaust, but if someone has been through this before and could lend me some advice I would appreciate it. Thanks

The answer is no. You must jack up the truck and use jackstands or cut the stock system. Unless you have a lift that you can use.

Agreed... I just put the stainless version of the Gibson exhaust on and I had to cut the factory exhaust. It's a pain to try and snake it out from between the rear axle and chassis. Without a lift, I'm going to say it's a no-go. (I tried ramps, jacks, stands... no dice.)

I cut mine right behind the muffler with a cut off wheel and a hacksaw. (My buddy had my sawzall.) Easy to remove after that.

Follow the instructions, and you should be okay. Don't tighten up anything until it says to in the instructions... snug is okay, but let it settle before you tighten everything up. Drivers side hanger is a POS, but workable.

Good luck!

I have to remove my stock exhaust sometime this week to make room for my new Corsa Sport system. I really hope I am able to remove it all in one piece. Rather not hack the stock system up if I dont have too. I guess I will find out.

I just had mine removed by a muffler shop today and installed a 14 in. magnaflow. Came off in one piece.

I had to cut mine but it was on the ground. I dropped the spare tire but there still wasn't enough room for the front of the pipe to clear the cross member. Now with the rear axle at full droop, there might be enough room for the muffler to be pushed far enough to the rear for the front of the pipe to drop down and clear the cross member. That'll all make since once you're under there.

And also, I don't know if there's more room for a 5.3L exhaust due to the smaller pipe diameter.

      2019+ Brake failure, it's complicated

      By needafix · Posted

      I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome.

      Next Friday will be my 6 week point from my right knee replacement.  The surgeon says it will be fine if I choose to drive after this checkup.  I know I could drive now but best to do as my surgeon (and my wife) tell me.  Richard compared being 62 to 72.  I remember when I was in my early 60's I was experiencing slow but regular decline in my mobility.  Thanks to good medical support,  i continued to fight the speed and spread of this decline. During my 60's I worked on non-surgical methods and just when I turned 70, my orthopedic surgeon recommended joint replacements.  In a little over a year, I had one shoulder and both knees replaced.  This hasn't been a terribly fun experience, but worth the discomfort as my future mobility health trajectory has reversed.  It is a treat to now be watching my mobility. balance and confidence steadily improve!
