Gotta love the 50s. Nice and deep, low rumble. Not too loud. Until you hit it. Thanks! Great comparison.

The 40 series flowmaster with a big block chevy.....there is no better sound then that!. Your car is beautiful. Thanks for rhe video.

I still prefer the 2chamber original 40’s, gives that ever so classic Flowmaster sound👌🏻👌🏻

The thing is : no matter what setup you use, that ride is always going to sound good.

This is an EXCELLENT exhaust video & comparison. Thank you!

That was a simple, but great comparison. Thanks for that.

I'm liking the Delta's. Thank you for sharing.

Your car has the perfect look for a 68 Chevelle SS. The color, stance, engine and trans, all just right. Even the wheels, well maybe Cragar SS.

idle gives you goosebumbs

Sweet ride, great sound!

love these! got 2 coming for the nova. peace

Always loved the sound of a H pipe with 3 chamber Flowmaster, I do it to all my vehicles... even my V8 powered Japanese Crossover.

Your Chevelle is beautiful!

Nice car my first car was a 69 chevelle I bought it from the guy across the street from me I was 141/2 years old I had to Waite 6 months until I turned 15 to drive it. I have a 427 60 over the short block is forged srp 30cc dome pistons the good gm dimple rods with a forged crank afr aluminum heads victory Jr. Intake and a atm 950 cfm carburetor turbo 400 with a manual valve body 3500 stall I'm getting ready to put it in my 88 monte carlo ss it will be a decent street car that can run in the 10 second index class on motor.

Sweet Chevelle you have there👍🏻

As older (68) hot rodder I really prefer the sound of the 50’s. A little mellower and they cut down the “tin can” sound of traditional Flowmasters which I personally don’t care for.

Got Flowmaster 40's on my 1998 chev truck , LOVE THEM! 50's too mild!

Great video I like the 40's

I like it! But I’m old school I love the original 2chambers can’t beat em but it still sounds good. I get the loud part but I’m already hard of hearing from too many years of loud exhaust and equipment anyway haha so give me the 2’s hahaha. Fine car that’s my favorite gen!!

No comparison Delta flow 50 sounds like music to my ears. Nice and clean

Wow …..beautiful sound…..awesome

From the sample, I can tell this is a nice raucous cam that would be right at home in a 60s drag car. The 40 lets that personality out. A cool cop should have no problem with it. On the other hand, if you want to be more lowkey or have a jerk cop citing for noise, the 50 is a better choice. If you use your car for long distances (eg. LA to Pismo Beach and back), you're better off with the 50. Loud exhausts --even when cool-- wear down the people listening. For what it's worth, I can still make out the cam's personality with the 50s. It's just not as obvious.

I BEEN USING THE SUPER 44 BUT THIS TIME ON MY 68 C10 IM GONNA GET THE 3 CHAMBER 50 NOT AS LOUD AND STILL HAVE A DEEP TONE THATNKS FOR VIDEO

Thank for posting- I actually like both but I think it would be less droning in the car with the 50 series. Now I wonder what the 50 series with an X-pipe would be like?...

My vote, 3 chamber and H pipe, always H pipe for the win. Or no crossover. Old school sound with no raspiness for anything older than say '93. Any pushrod motor except a Ford SOHC 427.

Nice, throaty growl. Sounds great to me.

Same with me. MangaFlow about the same money, but no umph! I've run 40s 44s 10s and outlaws, on various cars, and trucks. I'm flowmaster. Your car is bomb.❤

Personally i like the big block 70s, mellow cruise but aggressive throttle.

2 Chamber OG 40's all day long.

The 3 chambers sound great

Original 40s sound so good 👌

I like the more define lope provided by the 50 here, but ill be running Delta Flow 40 on mine.

Helpful. Thanks!

Music to my Eyes Beautiful

50 super or 50s delta?

sound good my brother i have 40 series on my 1990 k5 blazer i think my sound has faded they been on there over 15 years my engine was burning oil so i build the engine but from the old engine i got alot of mud out my exhaust tail pipes it may be in the mufflers also im gonne buy me some new ones..it seens like i dont have that bass sound enymore..i wonder how long theses mufflers suppose to last...the 40 series delted sound better to me nice bass in it ..i think i might change my mind and get them 400 series delted ..and by the way that cam you got in there sound real good..

No revs?

Howdy neighbor! I live literally right up the street (San Sevaine) just north of the 210. I'm kinda diggin the Delta flows on your BBC.

Great video... a lways helpful when looking for a new exhaust. Did you get the 50 series delta flow or the 40 series? Any idea on the dB level?

Wow big difference much better

Would you mind making a video of the 50 series exhaust at a similar distance as 0:52 in your video?

i liked the first one.

The 50s are just a tad quieter.i like them better over the 40s.thanks for showing us.great info

I love the flowmaster super 30s or the 10

Perfect

It doesn’t sound like it lost much of that normal Flowmaster tone, which is a good thing! Is it noticeably quieter inside?

Car looks great! What brand and model wheels are those?

Sounds great looking do the same for my 69 big block do you know the part number for the Patriot headers thank you

Any drone? Thinking delta 40

Drove to and from Pomona swap meet from the sfv....ears rang the rest of the afternoon. 2 chaber 40s went in the trash where they belong Dynomax ultraflows sound killer on a cammed up chevy. Had 50 series on a C4 they had a much more tolerable sound

I have 2 chamber Jegs Flowmasters and 3" full exhaust behind a 400+ hp 401 FE. Too loud. What percentage quieter do you think the 50s are compared to the 40s? Like you said, kinda subjective, depending on what it's doing, idling, part throttle, wide open. Mine is pure straight duals, no crossover. Too much of a cracking for lack of a better word, on both a sharp whack of the throttle and medium hard acceleration. I need to find something a bit quieter.

They both sound fantastic but the 3" system is off the meter for sound track. Thanks!

But no rev or drive by comparison?

Will you be at the Connecticut cabin fever car show in Naugatuck April 2nd and 3rd? I’m loving what I see for the line up so far.

Badass lit`em up!

Glad i have a house in the country alone.

What’s that 8.1 In the background sound like!?? Lol

The 3 chamber sounds deeper warmer and better

Super 40s will give you the deeper 2-chamber sound without the droning.

I prefer the h pipe and 3 chamber, had a deeper and much cleaner sound!

Wowww sweat

No question the 50s sound better. But what's the subject for people trying to hear this through their phones is the louder muffler sound okay at idle through the phone. But what people don't know if they were there and you gave it some gas and be raggedy loud sounding and that 50 would not

My ‘72 C10 454+0.030” has Hooker Super Comp headers 2” primaries...3” collectors, 3” Dr Gas x-pipe, 2 chamber Delta Flows, 2-1/2” tailpipes out the back.... nothing sounds better in my opinion! These snotty nose kids that think it’s all bark get a big surprise when they jump on it.....😂

2 sounds better
