Been tossing around the idea of having a muffler installed. I would leave factory piping simply cuz it's stainless. Had an Imco (identical to flow master) put on my last denali. Sounded great! Wondered what you guys have installed, if any. Thanks!!

Corsa or Borla cat back.

 

But so you know there will be "helicopter" noise when you go into V4 mode. Unless you have it tuned out, or install a Range device.

Do Magnaflow 12909 in place of OE muffler and flapper valve. Any competent exhaust shop should be able to cut out and replace with no issue. Including labor for install mine ran about $155-$160 granted I had a discount coupon from Advance Auto when I ordered. Great sounding at startup and a deeper tone plus minimal drone in V4 mode.

What is the "flapper valve" and did u have the resonators removed too?

I have an MBRP and honestly get nothing but compliments on how my truck sounds....... that said..... I wish the factory tailpipe wasn't such a goof ball design with the flapper and resonator in it as the MBRP 409 tubing will rot off this truck long before the stock system would have even shown corrosion. If it weren't for all the hacking I would have had to do I would have just swapped mufflers...... but by the time you delete that retarded valve and the resonator you may as well buy a kit.

Flapper valve is directly behind OE muffler and is designed to cut down on drone when in V4 mode. I did not have the shop remove the resonator and exhaust sounds fine.

This is me... not being cocky but for the 2014-up gm trucks this sounds amazing. I've since have clamped open my valve. And sound is way better. But invisible helicopter follows me

Thought of an exhaust. Built it in my head. Did a Lil research. Bought a borla and xr1 muffler. Corsa look alike tips and mandrel bent tubing.. yes I still have my 3rd cat. And yes i have my valve.. check out my other videos to hear more. I made a video of me crawling under the truck to show what I have

Am I voiding all warranties removing everything?

Voiding the warranty on your factory catback exhaust yes... anything else no.

      p0449, p0446, p0451 Evap codes

      By B07 · Posted

      Glad I found this post before posting a question. My ‘09 has been throwing those codes and P0442. I replaced the gas cap as it was trashed to begin with and the purge solenoid valve under the hood but still get the code every now and then. Dealership said I need to replace the vent lines as the previous owner use cheap fuel line that feels more like a balloon. They also said the charcoal canister and the “canister vent solenoid/service kit” so it relocates the filter up by the top of the transmission. Vent solenoid is cracked as the previous owner just let it hang loose. Too lazy to put it back on its bracket. If I put it on there the hose kinks and I thinks causes a whistle when I fill up.  Only issue is the parts guys can’t tell me which one I need as it shows two styles. One has a jointed section.  Here’s photos. What do y’all think?  Thanks.  I apologize for hijacking the thread.

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 3: Supposedly you need any cluster OTHER THAN a WT model cluster to have full steering wheel functionality. Went back to the part truck and removed the all terrain cluster, trim, and snipped as many wiring harnesses as possible to pull out the factory terminal leads if needed 😂 that poor donor truck…    As of right now I’m relying on Darth_Vader’s thread and YouTube videos. will update.

      Open Door Chimes When Key is Out

      By Another JR · Posted

      The “engine hours” display is there because the truck detects the key presence as you were thinking.   My first step would be to call a dealer service person and ask if this a known issue and how they deal with it. If you don’t get meaningful advice there, i would try a couple of DIY things before bringing it in for troubleshooting/repair.   It sounds like a mechanical key detection switch is stuck, but I have not actually seen what the internals look like. Maybe spray some Caig Deoxit (electrical contact cleaner) in the key hole and work the key in and out in case it’s an electrical contact cleanliness issue.  If that doesn’t work, next apply whatever lubricant GM recommends and work the key in and out a few times.    Good luck with it.

      Carbon on valves would be the least of my worries on a light duty, 1500-series pickup with 357k provided the engine still ran halfway decently. Everything else is likely toast, on its way out, or has already been mauled to death by cheap mechanics and backyard fixes. Those kinds of trucks nickel and dime a guy to death.   I wouldn't think having the top end cleaned once or twice would be a big deal on a 5.3 but maybe it is?
