I use sport mode also. One day I’ll try tow/haul mode. It seems like a more aggressive mode in “ normal ish” driving. Maybe I’ll try 4wd auto one day also.
I agree. I launch the truck in 4wd hi and don’t get any wheels pin.
I still have my S&B intake to install yet. Maybe I’ll end up doing a Diablo tune, maybe a low 13 second time….
I noticed it first when swapped transmissions in my 69 Dart in my dads garage. I had to cut the exhaust in front of the muffler. It sounded terrible after that and felt like it was making a lot of noise just to get down the road and seemed slower. My dad said once you get the exhaust fixed it will be fine, and it was. This truck exhaust was louder than I wanted originally. Same sensation as in my Dart for me. I’m now getting used to exhaust-replaced muffler and flapper valve with straight through muffler, kept resonators-and honestly kinda like it. Maybe just me.
So I’ve known about the phenomenon of a loud exhaust making the same vehicle seem slower. So worrying that my muffler replacement may be hurting performance I finally decided to set up my new dragy. Knowing the truck is sitting about 150 lbs heavier than when I went to the track where it ran a 13.61 I was hoping for a 13.7ish. The first run went 13.69, so I was pleased and didn’t believe the new louder exhaust didn’t hurt performance. I decided to do run more run for the heck of it, launch at a little higher rpm and it ran 13.59. So now I’m thinking maybe the exhaust actually helped performance. Who’d a thunk that.

Well, I now have a 3.5 in/out offset Magnaflow muffler for the truck. However I think it's gonna sit in my garage. The sound is really starting to grow on me. Maybe I'm turning into more of a redneck, but I'm liking the sound. So no Magnaflow for now.
I’m also believing what GM says about the flapper existing to help with gas mileage in less than 8 cylinder mode. This thing is sucking gas now. No I haven’t been getting on it more, actually seemingly less because it’s so loud.
Quit bullying me. Lol. I’m still pondering my choices…as I’m liking the sound a little more.
I took it to the exhaust shop to do the current work. Let’s say I don’t want to tamper with the stock y-pipe. I just don’t want this stock truck sounding like a race truck, something it isn’t. I just wanted a little more sound.
Well glad I know that now. I’ll look into the vibrant resonators. I also thought about a Magnaflow 14151 (14” case straight through) in addition to what I have now, or replacing all of what I have now with a 12909 22” case offset muffler, or to eliminate the inconstant sound throwing the stock stuff back on….or…
I’m not messing with the stock y-pipe.
Well it’s a bit pricey for me and this leased truck. And the corsa sport system was 3”, I didn’t really want to go smaller. FYI, I also got an S&B intake for Christmas I’ve yet to install.
Does anyone notice the engine/exhaust going silent when letting off the gas? Not just not very loud, but silent. On decel my exhaust goes silent, then roars back to life at about 5 mph when coming to a stop, not touching the gas pedal. It’s strange.
It’s a cheap $28 bullet muffler, the offset tubing was free, and the bottom portion in pic was $20. So after ho humming for months I pulled the trigger and deleted the muffler and flapper (I only had one). It’s loud, too loud. Don’t know how people are deleting the muffler and standing it. But.. what’s weird is how the engine sounds on deceleration. It’s like it shuts off. At slow speeds it’s actually not too noisy, but when letting off the gas, the exhaust goes silent. Then at about 5 mph while slowing down it sounds like it suddenly fires back up. Odd and annoying. As loud as it is I’m missing out on the deceleration rumble of a v8. it’s a cheap
If you push on the front pass side it opens all the doors. How did you survive before 2019 when there was no exterior buttons on Silverados or Sierras?
