Hey all,

 

Comparing exhaust and I am having a hard time figuring out what I want.  I have a LT Trail Boss.

Reply with what you got, opinions, interior drone if there is any, and a video is possible.

 

Thanks.

This thread really took off without me checking on it much.  I ended up going with the Flowmaster FlowFx.  Didn't break the bank and sounds pretty good.  Slight drone on the highway but nothing the ti

Borla Attak. No drone. Sounds good. Only really loud when mashing on the gas pedal. Sent from my iPhone using Tapatalk

I have the same model, tried a flow master, not much louder than stock though.    The truck has a big cat and 6 diffusers making it more prone to quietness.  Solution was to remove the muffler, much happier now.  Good growl when accelerating, mild at speed with no drone.   Surprisingly cheap to do also.

ya i just dropped 250 for a flowmaster 50 and got little to no sound improvement. are you saying just cut the muffler out altogether? will that be too loud to hear the radio? i do have a whine that i think is tires starts about 20 MPH. id like to drown that out with exhaust

Yep, just cut out the muffler and do a straight pipe there. It's not loud in the cabin and no drone.

yep, just have a straight pipe now.  Not sure if there were any flapper valves when stock, but there gone now for sure.  Sounds great, no drone.  Should be about $50 at a muffler shop, maybe 20 mins to finish.

Yeah the Duratracs are a noisier tread design for a mud-AT hybrid tire IMO. Make sure you rotate them frequently. 

 

I just posted the straight pipe videos to show a cheaper option for the guys with dual rear exhaust. Sounds like there isn't much of an exhaust volume increase without removing the flapper valve and going with at least a Flowmaster 40 or even FlowFX muffler. I thought the FlowFX sounded pretty good. There are also mesh screens on the section of of exhaust piping near the spare tire. There are 3 screens on each of the  two dual exhaust pipes.

This one sounds good IMO. I like that it's a SI/DO with new new tailpipes and works with existing bumper exhaust ports.

I have an electronic cutout on mine so I have the best of both worlds, loud when I want it and quiet when I dont.  See videos below.

Try to make an exhaust clip. Fly-by and cold start videos are the best kind to capture.

Ordered the Corsa Sport today for my LT Z71. They said 10-14 days to receive. I’ll be sure to post a video and impressions once installed.

So the flowmaster 50 has some rumble to it with the screens taken out? 

I want a new muffler but nothing loud in the cab and no drone.

      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!
