^That. There's lots of different versions of chambered mufflers.

This is what they were in the '60s/70s:

Glass packs have a nice sound, especially the longer 30-inch ones, I prefer them over the newer muffler options except for the ultra quiet ones.

So quite a few years ago when I installed a fuel pressure regulator I was kinda broke and used whatever old hose clamps I had in an old coffee can. Whilst pondering the engine bay a couple days ago, decided to install all new 3/8 fuel line since it has been on the truck for a long time in the desert , and use proper size 3/8 hose clamps this time. Bonus is that I found an unopened/unused DEI heat shield thingy for the fuel line. Finished up about half an hour ago and it cleaned up real nice and makes me feel better...

My brother's '13 Shelby sounds like a beast, but a quiet growl. I've heard a Camaro sound similar. I don't know how they get that sound, but it's better than anything old school that I've ever heard.

I love the glass pack sound.

I was running a set of Dynomax 18" Racebullets they were way too loud basically just made the headers deeper sounding not quieter. Could be due to 3" slip collector into 3" pipe and mufflers. Went to the Ultra flows basically the same muffler in an oval case with more packing still straight thru they are still loud especially when in it hard but much more livable.

Not a good way to see how loud they are.

I've always played with/changed exhaust on my vehicles and love playing with system designs, plus I like trying new mufflers. Headers, X or H-pipe, size of pipe and overall design of the system all play a huge role in how it sounds. My C10 has 1 3/4" long tube headers, 2.5" pipe with an X as far forward as possible in the mid-pipe and piping out the back, turning 90* and exiting behind the tires.

Originally I had Borla ProXS mufflers mounted in the OE location. Had a unique tone to it, sounded really good but a bit quiet for my taste. As they wore in, these got to where they droned REALLY bad. These are a straight through muffler with fiberglass packing in an oval shaped body

So when I swapped the 4L65 out for a T56, I decided I wanted to try some Corsa Extremes. Technically, these are chambered mufflers. But it's a straight through pipe inside with 3 little slits toward the outlet that tune out certain frequencies, their claim to fame is that Corsa's have no drone. These are loud AF but have zero drone whatsoever in this system.

I also mounted them behind the axle this time, so the mid-pipe has the X in the same spot but there's LONGGGGG straight sections after that till it turns over the axle and that allows the sound waves to bounce and reverb really bad, creating the old straight piped clapped out 350 "clap" under part throttle. I HATE that, so I have some resonators to swap in those straight sections next time. I also figured out (about a year later) that the muffler shop used 2 1/4" pipe to make the 90* bend out of the mufflers, that coupled with the 90* probably also adds to the clap

You can hear some of the clap here
xc_hide_links_from_guests_guests_error_hide_media

But these mufflers sound awesome at idle/revs/full throttle IMO

But just to show how the whole system effects the sound, not just the muffler, I also have a single one of the same Corsa's on my daily Z71. It has stock manifolds, cats, Y-pipe and single exhaust. It has just a hint of drone and it's a whole lot deeper/has more of a growl to it than the raspiness the C10 has

And this is the same setup with the stock muffler, big Corsa Touring muffler with 2 different tail pipe versions, then the small Corsa Extreme. Quite a difference even in just the idle

Mine are super basic 1.75" fender well headers with 3" slip collector, 2x 3" 45s, 2x 3" couplers, 2 x 45" sections of 3" pipe, 2x Ultra flows, 2x 3" 90s, 2 band clamps, and 2 hangers. But I'm also running a fuel cell in the bed and not the stock tanks. The metal part of the fillers are still in place to hold the gas caps so I don't have holes in the bed sides.

Thinking about adding a set of cut outs where the couplers are so I can flip it to open headers. Was going to do it originally with the manual ones but have been looking at the electronic ones recently.

I wish the electric ones weren't so expensive. I've always thought it would be cool to do a dual system where you could run cats/resonators in one stream and then bypass them for just open headers or just mufflers

I meant the 60's type. Like this:


And as far as the SpinTechs go, I have a pair on my van with no tailpipes. The drone really isn't that significant like a Flowmaster 40 would be.
