Muffler delete

[Kc4O]

5.3l with stock muffler, resonator, and valve cut off. I welded in a flowmaster 40 series. Gives the v8 muscle car sound. There was a little drone until the muffler was broke in... Now there is nothing. When your not on the throttle it's just a little rumble. When you hit it good it sounds like it should! I can post a video in am if you like...

On the highway do you get that low tone that echos in the cab?

No once at speed it gets quiet unless you put your foot into it.

I did the same with my set up 6.2 L with a 12909 Magnaflow 3.5". Remove OEM muffler, resonator and flapper valve... I have not looked back... At first I did the muffler delete with resonator in place and it was too loud for the neighborhood along with v4 mode drone. Now v4 is not a big deal as I notice it about like stock. Good luck with your choice.

Do you have any sound clips? I have the 12909 with flapper removed and resonator still on. I am considering removing the resonator for a little extra sound.

Here is an exterior only video of my muffler delete. I have no interior video clips.

I had muffler delete on my 14 GMC as an experiment before going with a performance muffler. It wasn’t loud really after initial start up. Lite sound cruising, more on throttle. The resonator is really no different than a glass pack. Then you add the cats can’t expect too much noise. Evidently I put a performance muffler on, it went back to stock sounding. At 59 years old my loud exhaust was a thing of the past for a daily driver. As far as sound quality that’s in the ear of the beholder.
