i like the stock set up, it keeps your truck stealthy and quiet, only mod i did was pull the flapper out and weld in a replacement pipe.  the stock exhaust is necked down to bump up the torque output for improved off the line grunt.  loosing torque to gain horsepower seems like the equivalent of loosing muscle mass in order to improve your yoga stretching skills. i'll pass..

Finally had the tips moved to rear quarter flush and with a slight stagger.   Sent from my HTC One using Tapatalk

Just had a Flowmaster Series 50 Delta Flow installed yesterday. Just a direct replacement of the stock muffler and removed flapper. Sounds exactly like I was shooting for, still muted and not at all obnoxious, but can now actually tell it is a V8! I didn't want much noise inside at all and it is great, you can hear it but it's not intrusive. No drone at all, except of course when V4 activates and then it sounds terrible but that is going away as soon as my Range AFM disabler gets here. I was a little worried that the 50 Series Delta Flow would be so quiet that you could hardly tell the difference from stock, but that's not the case at all.

I went again with the GMC Borla (which is the Borla Touring exhaust that is tuned to GM Specs). I had this setup on my 2015 Sierra and it was great

I'm running a black widow race venom 2.5 i/o in place of the stock muffler. Flapper removed as well as resonator.  With the resonator on it sounded stock still. Once off you could tell the difference. No drone at all (afm is disabled so can't speak for v4 mode). Its not loud inside while idling or cruising but it screams at wot. I don't like stupid loud and like to hear people talking to me from the backseat. I was worried this was going to be too loud as I have always ran their 250 series prior. CAI didn't do much but make the note a little deeper. I think the 250 series has a deeper tone than this and may go back to it once I install long tube headers.

Just got a 40 series put on yesterday, 3.5" tips. Love the sound. Not obnoxiously loud cruising through the neighborhood but loud when you get on the throttle. Love the low rumble. V4 drone is there but way overblown.. will tune that AFM out soon.

Side exit. Gibson MWA Muffler. AFE ypipe

hows it sound? 

i like my buddies gibson on his 5.0 F150 and their cat back for $500 seems to be a nice middle ground. 

i just want some sound but drive almost all highway so no drone is a must (not worried about v4 mode)

My setup honestly has no drone as long as you aren’t in 5th or 6th Gear just chugging along at a low rpm 

 

everyday normal driving for me I honestly have no drone in the cabin. 
 

these MWA mufflers have no packing in them so no noise gets caught In the muffler. The sound just flows out. I 100% do not regret getting the muffler and love how it sounds.  You can check a sound clip here.  This is before my side exit. But that’s all that changed was the location of the tips. It got a little louder but nothing crazy.

Never messed with the oem exhaust flaps. That all got removed when I did my Gibson dual sport cat back
