2014+ Exhaust Systems & Mufflers

GreyGhostZ71 · September 21, 2015

Guys looking for some suggestions

I have a 6.2 and had the muffler chopped off almost a year ago. Left the resonator and flapper, and the sound was great. No drone, chopper sound etc

A few months later the flapper would act up and rattle like crazy very randomly. It drove me nuts, and more recently was getting a bit of a rattle for a few seconds at start up. Dealer won't warranty cause I've chopped the muffler

Anyway, had enough of it and wanted a new tip setup so took it into a shop a few days ago to have the tips done and flapper removed. They said removing the resonator wouldn't affect the sound much and needed to pull it to create the set up I wanted (two black tips side by side Corsa style) so I said fine

Picked up my truck alter that day and fired it up and its crazy loud, especially cold start. Its a bit too much. Piss off the neighborhood loud. For city driving its fine I could deal with it but I do lots of highway driving and the sound/more drone would be too much. Chopper sound isn't bad, but is there a little and the drone at some rpm ranges is worse

I'm looking for a muffler, probably Borla hoping to tone it down a bit and of course reduce possible drone. Any suggestions? I am also considering throwing the resonator back in where I chopped the muffler off originally to tone it down cause I think its a straight thru design and would fit. I should have paid for a cat back right off the bat but hoping I don't have to go that route now that I got new tips etc

What are thoughts or experience on throwing the resonator where the muffler was, or muffler recommendations. thanks

Any videos??

I did the exact same thing in my 6.2 and I'm wanting to go louder. Lol

Hope this vid works. This is no muffler, flapper or resonator. I've since put the resonator back on, toned it down a bit.

There are definitely times when I miss it loud like this though haha

Has anybody tried out a Craven muffler? I found it while searching YouTube videos. There aren't many specific to 2014 or 2015 Silverados or Sierras, but they have a few videos of the older Gen's.

Has there been a diagram of the stock exhaust system posted anywhere? I done some searching around and haven't found one. Just trying to get a visual of it and where the different cats, mufflers, valves, etc. are all located.

I am going with a carven R setup....

tho i want to know what setup will get me the best results. I was thinking some pacesetter headers with 3" tubing to true duals and a X pipe.....or an i better off with a Y and a single 3"??

Where would you install the X pipe? I thought there was a single pipe going into the muffler.

True duals.... From the headers all the way back.

I just domt want there to be a big loss in back pressure to where i will loose HP/TQ

Magnaflow 18" on 2014 sounds a lot different than the 2012 . The short stroke 4.8 Vortec sounded close to the older high revving 327/350 Chevys,the 2014 5.3 DFI seems under no stress at all with a mellow tone. Thinking of replacing 3.5"x18L Slash cut tips with 3" inch tips and adjust the pipes up a little. Gibson 15 deg. cut are the only 18" bolt on tips I could find.

Had it in my mind to go with another tip so first chance stopped by a Custom Muffler shop yesterday. After checking it out Mr.C said 3.5 tips looked good on type truck I have and other shop did a good job . Said really couldn't do any better unless wanted to change to side exit. So if it looks good to him looks good to me. But knowing me will want to change to a different setup in a year or two.

It will be a Turd with dual 3" dual pipes, you would be better off with a single 3" and Y-pipe and good headers and pacesetters are not good headers. Kooks or ARH's are top notch products.

The Best.... Thats Subjective and without getting into a Header war IMO I like ARH but Kooks and Stainless works I would not have an issue choosing either.
