"That's how they all should sound" amen

The 40 series and super 10 sound the best in my opinion. I have a true dual exhaust; Long tubes to magnaflow cats to super 44s dumped 3in before rear axle on my 97 suburban all tucked between the frame and body of the vehicle so that it doesn't get damaged if the frame slid over some rocks.

The Red Stepside sounded best imho

My man said that is how they all should sound hell yeah bro

I love the sound of the flowmasters when when 4L60E starts slipping through the powerband 🎷🎷🎷🎵🎵🎶🎶🎶🎶🎼🎼

the last one as good as most of the super 10 and it's still like that the 40 but number 10 is the best.. when I hear it it gives me goosebumps

My 92 Silverado has the Super 10 sound like the last truck it's music to my ears 👍👍👍👍👍

Red step side was my favorite.

Whenever you said “thats how they all should sound” that was the biggest head nod ever from me! Love it!

My pops had a 1987 1500 single cab step side when I was growing up. 3 inch lift on 37s and fully straight piped. Currently on a mission to find that truck again. You can throw all the newest trucks at the market at me but I’ll always take a straight piped 70s-90s shitbox

The super 10 sounds the best out of those 4. I personally am in love with my setup. I have a 95 k1500 extended cab short bed, took the converters out and im running a customized 40 series single in dual out with 3.5" angle tips turned out at an angle at each rear bed corner. The 40 series was cut in half and the rear dual outlet plate was cut off and welded back onto the front half. Basically it's the front half of a 40 series and welded the dual outlet end plate back on it. Its a little louder than I wanted but it has a really nice sound to me. I have access to a muffler shop and tried several different used mufflers before I came up with the idea to cut a 40 in half. Since then I've done a couple for friends some from front half of a 40 and some from rear half. Mt favorite is the front half of the 40 series. Oh yeah, all of them I've cut were used mufflers that were taken off for rattles due to broken baffles, I just weld them back while I'm in it.

Used to own a 5.7 and I ran a 2.5” pipes with a flow master super 10 without cats. Best sounding 5.7 I’ve ever heard and loved the exhaust note. Always got great comments on it. Try it out some time on one of your customers trucks. They’ll love it

It even powerful enough, their was this guy back when I was in highschool who had this 89 Chevy and it was a low rider and the exhaust was so loud and powerful, you could hear it streets over, and it wasn't like an over powering loud, it was like a POWERFUL loud.

Nothing beets the sounds of the v8 engines especially when it’s straight piped I love it

Straight pipes, take the muffler off leave the converters on, run the two pipes out behind each tire. I have a 1997 with a 5.7L ( 350 ) done like that, sounds great !!!

I have a 91 that is 3 in straight pipe to a side exit right before back tires. If you like loud and like to hear your truck definitely would recommend. Your neighbors will love you in the mornings to. Waking them up with the sweat sound of bald eagles will make there day.

Because of how big the stock cats are, those trucks never sound good unless you take those out.

Super 10 for the win💪🏽

my '95 Chevy Cheyenne 5.7L has the Super 44 and I luv it

Nothing beats the sound of that 40 series!

I know it’s the quietest but the sound quality of that magnaflow is fantastic.

Flowmaster is the only thing for a chevy truck. My 89 C1500 is a true beast true duals, supper 44 on each pipe, and no cat. Also gotta get a cold air intake or your just doing it for the sound, more air that can come out means you can put more air in.

I like the sound of the 40 series flowmaster. Doesn't have as much pop sound like the 10 series does.

“That’s how they all should sound”… Amen 🙏

Onboard GoPro or something similar will help the drive off sound. During windy conditions on your phone/camera or any recording device, a quick tip is to use a a regular dish wash pad like Scotch. Just the yellow scrubber laid over the mic. It’ll remove wind noise and keep most of the sound. I love these videos,evertime I need a sound clip I find your shop! Love it!

I’d like to hear a 14” magnaflow and maybe a magnapack on the 5.7

The red side step #3, was the best !!! Nice work guys. I like how your #1 rattles but it seems to be a bit loud in the cabin ...

Dude we went “ohh” at the same exact time on that last one maaaaan them all sound good. Music to my ears!

This video gives me chills! Love it!!!

I know GM made heavier duty trucks than the 1500 half tons in the older GMT400 body's and many more powerful later models but I swear, for what they are they're some really durable and tough work horses if you maintain them properly. I bought a '92 model K1500 Silverado 5.7 used back in 2008 for $2200 and with almost 400k miles on it today, I still work out of it and maintain it and it just keeps earning its keep over and over and over again. It never had the best factory paint on it like alot of the 88-98 models did but I just recently got my first rust hole on the bottom corner of the ds ext cab at 30 yrs old lol. I bypassed the AC compressor years ago but aside from that everything still works! I have the stock converter into a FM 40 series dual outlet with 3"×18" tips and it sounds just right for me. Great videos brother! Take care👍👍

On the pre-93 (I think) trucks, they use that big pellet style converter, which is what keeps it quiet even with no muffler. I always pop the plugs out and drain/remove the pellets, tack the plugs back in and they flow and sound much better. You probably won't pass emissions if you have it, but it'll pass a visual inspection.

My truck has the super tens with only one output it has the cat converters out it sounds amazing

Definitely the flowmaster40 on the ‘90 step side. I’ve got a ‘97 gmc 5.7L that I’d love to do this to.

I'm in the process of building my k1500 5.7 5speed with header dual cat 2.5" to single 3.5" resonator to 3.5 flowmaster flowfx to single 4" exit can't wait to hear it

I have a 93 with an axle back exhaust and Dino max muffler I would like to upgrade to a dual out with 3.5 tips

The red stepside is a sweet truck

Thanks for the chance to see and hear the different set ups. I have a 98 2500 it is a beautiful truck from front to back. I am thinking of changing the setup great video

I got a 98 Chevy ext cab 5.7L v8 and it sounds amazing

I love all the flowmaster exhaust sound but the super 10 is my favorite I used to own a 1997 gmc sierra 1500 and I put true dual cherry bombs under that truck but I should have put true dual flowmaster under that truck !!!!!

They all sound great 👍 👌

That true dual Flowmaster 10 sounded the best

That was a good comparison. Thanks for putting that together. I liked the red the best, if you were wondering. Can you do a comparison for Vortec 454's please?

I run long tube headers 2.5 mandrel bent thru Y pipe with 3 inch down pipe to a S44 flowmaster with duel 2.5 out mandrel bent sounds ruthless and very aggressive tone next will probably 10 series flowmaster serious muscle sound

I have a 40 series on my 5.3 silverado. She sounds really good. My grandpa was even surprised how good it sounds.

I'm stuck on the second one and the last they both sound amazing

The red one sounded the best by far!!!!

I have 2 10 series on my v6 , nasty at high rpm! Mustang, but!!! But but! I just bought a gmc 89! Steel and blood and excellent memories 👌

Both flowmasters sound good

Porter Mufflers. Stainless steel wool packed. Last forever. Great sounds.

The dual in dual out flowmaster10 did sound the best but what would have sounded so good would have been true duals wit 8" glasspacks on each pipe and ran 2 3/4" pipes w/0 cats and a set of headers now that a rumbling sound that you never get tired of hearing

The last one is my favorite

I want a stepside soooo bad but i kinda like the way my 90 single cab silverado looks, super sleek imo

I had a 1993 Cheyenne and then a 1997 Cheyenne, both were straight pipes with no muffler, dumped just beyond the rear axle. Even with the V6 they sounded real deep and real mean. I'd love to see someone request that.

Best exhaust for em trucks is headers, straight piping with cherry bomb glass pack , that’s it no cats!

Really liked the last one 👍👍👍

I've got a 98 Silverado 5.7. The exhaust I have on it is 3 inch true duels from about a foot back from the manifolds all the way out the back. Removed the converters. It's got flowmaster supper 44 mufflers and 18 inch long by 7 inch tips, it sounds super mean. I've had so many people stop me on the road to tell me they like my exhaust and ask what it has.

The last one was fire!!!

My 94 silverado had Flowmaster 40 Delta Flows true dual. No cats. Its sounded too good 😩😩😩

Installed super 10 on my truck after watching this video

The super 10 is the best one 🤙

I have appoint at 10am to install Flowmaster 40 series on my 98 C/K 1500 vortec 5.0 . No cats

Red step side 100% what would it do jumping the diameter size Cat-back

Super 10 flow master sounds sweet dualed out the back

Thank you for posting this video because I’ve been looking for the exhaust slash muffler to run I’m Silverado obs and 5.7 and this really helped out thanks 😀

The 1500 with the super ten was nice in my opinion. I have a 99 tahoe true straight piped but it’s raspy so I’m considering adding universal cats and maybe the flow master super 10. Regardless really great video well done

The good ol super 10

Red step side and the last one

man that super 10 has the perfect combo of low grunt and rasp

Thanks, need to get some of this on my 96 Suburban!!

Straight pipe sounds like a true v8

True dual cat back with 2 1/4 piping with 5 inch tips angled at 45 degrees make the sound on these trucks

Got glasspacks on mine and it sounds beautiful!

The last one though 🔥🔥

Best sounding setup is no muffler but leaving the one cat, that’s what I have on my 87 305. Has a nice rumble but not abnoxiously loud.

The Super 10 sounded awesome!

The super 10 is my favorite

I like the last truck 👍

I put a flowmaster 40 in my 98. it's duel 2.25 in 3" out turned it down before the rear axel. Sounds real close to the red step side.

The red one sounds good

X pipes?

I just bought an 88 c1500 stepside it has stock converters to 2 flowmasters then dueled out the sides.

Now that’s how a v8 should sound

Thanks for the video. It gives me some ideas about what to do with my '96. It has a 350 and a 5 speed transmission.

Take those cats off if you can. Did it with my 94, it got a little louder but not much. It’s better for the engine too

I like Jones mufflers too. They are decently priced and sound good.

That stepside made my feel goods feel good

2 and 4 are best. But they all sound good.

Would like to hear those 40 s with headers in front of them

The 1998 song 🔥

I have a 3" flowmaster 40 with a cat delete, and long tube headers it sounds just like that red one

Thanks you helped me to made my decision straight pipes for my 1990 chevy 1500 350 engine

hard to beat flowmasters

I have a 96 gmc sierra just like that 90 pickup thinking dog doing the same exhaust on mine

Thanks for the video now that I heard them I think I know what I’m going to do

The first truck and the red step side

I have long tubes to a flow master. Sounds amazing!! And it doesn’t clap out lol

How much was the 40 series setup on that stepside ?

I'm working on a 94 chevy 1500 Silverado ... I took out the old 305 and I'm installing a 97 5.7L small block. now when I started I didn't know that the complete exhaust system was pulled out already and the engine that I'm putting on had some sort of homemade stuff on it .. would it work ?

My vote #2

I have the flowmaster 40 on my 98 short bed 350, dumped under the cab but it is way to loud for me. I was wondering if running it out the back would make a difference or should I change the muffler its self. I still want an aggressive rumble but I also want to enjoy a conversation lol
