3" Flowmaster 40's vs Delta Flow 50's - Big Block Chevelle

A quick comparison between the 2 chamber Flowmaster 40's with an X pipe vs 3 Chamber Delta Flows using an H pipe. I made this change and couldn't find any good videos so I made one.

[@jasonkaiser1292]

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

[@markwaltman1524]

No doubt

[@danmyers9372]

Too tin canny sounding for my old ears. Flowmasters make everything sound like a 1980’s 5.0 Foxbody. I guess if you grew up in the era. I grew up with glass packs.

[@jawahnthompson6306]

@@danmyers9372 glass packs are garbage to me. just end up blowing the fiberglass out of them with some power

[@powerband5235]

40s sound way too good 👍

[@ralfbond258]

indeed

[@dougmurray7684]

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

[@brandonwoods9866]

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

[@aapddd]

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

[@user-qc7hr4my7r]

I run the 50 series delta low profile mufflers on my 68 ss 396 which they don’t make any more. Love the sound of them, much deeper then 40’s.

[@buzzzmiller]

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

[@vdrivevideo]

Thanks for watching Buzz! I'm not expecting a million views from this just hoping to show these results. Finding the right sound is difficult as you well know.

[@dannydennis318]

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

[@davidkeeton6716]

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.

[@vdrivevideo]

Thank you Sir! I like the Cragars too but prefer the aluminum drag wheels . 👍

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

[@danmyers9372]

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.

[@driverjamescopeland]

I'm with you. That tinny sound is what's so intrusive when you're trying to have a conversation. Their 50-series Big Block SUV muffler is the best muscle car muffler I've heard.

[@Sir.VicsMasher]

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.

[@richardsmith-qy6vl]

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.

[@davidkeeton6716]

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.

[@markwaltman1524]

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!!

[@leosun8469]

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?...

[@rondellasvisuals707]

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

[@powerband5235]

Original 40s sound so good 👌

[@overcastfriday81]

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.

[@rickydenardis8597]

Great video I like the 40's

[@thund3rxiii469]

40's are for sure the move. I've ran them in both my current and previous trucks. So mean, yet humble.

[@davidkeeton6716]

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.

[@vdrivevideo]

It’s hard to describe but the difference is noticeable both in and out of the car. The 50’s are a deeper yet quieter note. Also noteworthy is the cross pipe. It also tames it down a tick as well as adding a smoothness to the lower rpm range. I highly recommend the cross pipe and IMo I even like the cross pipe over the x pipe. Good luck and thanks for watching!

[@gordocarbo]

50s are notably quieter but they make 70 series that really pipe things down but still have the FM exh note

[@gordocarbo]

@@vdrivevideo Only put on an X to help kill high frequency noise to quiet it down Best exh I ever had was duals with no crossover at all sound wise. NExt choice would be another H

[@cliffklimas8324]

Agreed!

[@rexspangler4641]

I listened to this video again and definitely the 3chamber and h-pipe sound so much better:did you ever consider the borla pro xs? These mufflers have a very aggressive sound with very little drone. Oh by the way, good-looking chevelle!!

[@Blusmbl]

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

[@vdrivevideo]

Significantly quieter inside. It's a deeper yet lower decibel sound imo.

[@Blusmbl]

@@vdrivevideo awesome, thank you. My car has 3.5” pipes, 2 chambers and no tailpipes. I love the sound but it’s too loud. If going down to 3” pipe, delta flows and tailpipes quiets it down but keeps the tone I’ll be happy. Yours sounds great!

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
