There are a lot of examples on YouTube on our trucks. do a search on there and you can get an idea of what kind of sound can be achieved.

No I still have the resonator on. But if I take it off, wouldn't it make the check engine light come on?

No. Many of us have had the exhaust resonator cut off for years. No CEL and no issue with state/emission inspections.Trailblazer02 said:
Huge difference in exhaust tone. I have the stock muffler with the resonator cut off and am pleased with the sound.
Also, removing the intake resonator will change the tone of the engine and exhaust as well.

Okay well ill try that first and go from there. Thanks Yall! I'll let you know how it goes

Not only do you get a better sound, but it cleans up the rear end. You can buy an exhaust pipe, exhaust clamp, and bolt on exhaust tip from either Auto Zone or Advance Auto to use in place of the resonator. You can go side or rear exit.
Some members run with nothing after removing the resonator. All personal preference.

^^^ I would advise against this...dmanns67 said:
With no "tail-pipe", you would have the exhaust cavitating under the passenger cabin wihle sitting at idle.
Our safety inspections require the tail-pipe to exit beyond passenger cabin.
With a sawz-all, I was able to cut off my resonator right after the hanger, leaving the hanger in-tact.
I then welded the small end of a Dynomax 41437 into it,
and welded a length of 2.5" into that, and cut the pipe right at the edge of the bumper.
It added a bit of a rumble to the exhaust,
but I really like the fact that it no longer looks like an import from the rear
.I will replace the muffler with a magnaflow, when the time comes.

We have no such inspections and I let mine dump after the rear hanger for a good while and never smelled exhaust even idling on trails or in traffic.
Personally I changed over to custom catback with a hooker aerochamber and enjoyed the sound for years, but it seems after the years a weld is broken in the muffler and while no one else notices, I can hear it vibrate. Going to try a Magnaflow this time.

I ran with it cut off for a while too. Once I did smell a bit of exhaust but I don't know if it was from that or the leak further up front near the cat. This was about a month before the pipe split on me and became a loud smelly nuisance 
Since I had to replace the whole mess (totally rusted out) I got the new pipe exiting behind the rear wheel.

It's the fumes you can't see or smell (aka Carbon Monoxide) that will kill you...Sparky said:
Fortunately for some of you, Chevy packs the seam-sealer well on the GMT floor-board...
My common-sense tells me that exhaust gasses are hot... heat rises...
If your exhaust is dumped under your car, the exhaust gas will rise and cavitate under the floor.
If there is a crack in that floor, the exhaust will enter the cabin.
If all of the windows are rolled up, then...
But hey, whatever floats your boat.

You have a good point, and I thought about this before removing the resonator...Then I thought about all the years of driving carbureted street cars/hot rods with turned down exhaust (before the rear axle)...I probably wouldn't ever want my kids breathing any of that stuff, but heck, I turned out ok...Except for a minor twitch now and then ;-)808_LS_EXT said:It's the fumes you can't see or smell (aka Carbon Monoxide) that will kill you...

LOL... Yupp, one of my Camaros had thrush header mufflers bolted onto the header flanges,,, no pipes.The Neens said:
.... BUT, it didn't have A/C and I didn't drive it like that with the windows all rolled up
You're dating yourself now...Were they Blackjack headers?808_LS_EXT said:LOL... Yupp, one of my Camaros had thrush header mufflers bolted onto the header flanges,,, no pipes.

First understand that any car/truck manufacturer will not put an item on a vehicle if they don't have to.
Everyone seems to discuss the rumble/growl that they hear after cutting off the resonator.
When you sit in your truck & hear that "nice sound" it's because the exhaust sound is echoing under the vehicle & the vehicle is acting as a sound board for it. You may not even notice it that much from the outside.
As mentioned earlier, any exhaust dumping under the vehicle could potentially end up inside the car. An exhaust system can be designed/installed to sound good and pump the gases outside the influence of the bottom of the vehicle.
When I need to replace mine the exhaust will have a muffler (type - unknown) but no resonator few, if any sharp bends and exit out the rear.
