Flowmaster 50 series Delta Flow or Dynomax Super Turbo

Currently have 40 series Flowmasters on the 65 - headers, 383. It's so loud, the drone is awful, I actaully do not enjoy cruising in it and forget the radio, it sounds nice when I'm not in it, but other then that... AGGGHHH.

So I have 70 series on my 70 BB and like them but they are kind of quiet and big so don't think I'll go there for the 65 SB.

I am not concerned on the performance aspect, but more sound. Like a good rumble but don't like the drone and too loud (my son loves it)

So looking at the 50 series Delta flows and my freind recomended the Dynomax Super Turbo 17749, which are at least 35.00 cheaper per muffler, thats a plus.

Just curious if anyone is using either or has used both and to just give me your thoughts and opinoons on sound.

Thks

I also had 40 series on my 66 Chevelle and had a bad drone when driving. I switched to the 50 series delta, drone was gone and it had almost the same sound has the 40's.

Re: Flowmaster 50 series Delta Flow or Dynomax Super Turbo

Dynomax Super Turbo flows far better than any Chokemaster. It has that "muscle car" rumble at idle and low speed and nice, not too aggressive but noticeable, sound at WOT. No annoying drone, (even with 3" exhaust) you can actually have a conversation while cruising without raising your voice.

Re: Flowmaster 50 series Delta Flow or Dynomax Super Turbo

I've got the Dyno Max Super Turbos on my 70, I absolutely love them. They have a nice deep rumble at idle and while you are cruising they are not loud but have a nice deep sound with no droning.. If you stomp on it, the car sounds like a muscle car should.

The Dynomax sounds like where I want to go, I love a rumble, but just don't love the drone and loudness. Especially that I am primarily a cruiser.

Re: Flowmaster 50 series Delta Flow or Dynomax Super Turbo

Magna flow for me. I had the muffler shop stuff in the biggest ones they could under there. My 454 is not loud, but not quiet, especially when I step on it.

If you lend someone $20, and never see that person again, it was probably worth it.

Re: Flowmaster 50 series Delta Flow or Dynomax Super Turbo

There's a lot of good advise here, and you can't go wrong with the Super Turbo's. The 17749 is a 20" muffler, the quietest one they make. They also come in 14" (17734) and 16" (17629) so you can pick your sound level. The 20" seems to be the hands down favorite for those who want peace and quiet while cruising and an awesome exhaust note when you get on it. Plus, they will support 700 HP so you can't beat that. Having said that, the 50 series Flowmaster will flow fine for mostly all of our street driven cars while eliminating the drone of the 40's. There are 2 levels of 50's- Delta and Super. The Super 50 is the quieter of the two, but still retains the bass tones that FM is famous for while eliminating the drone. A 70 series is a Super 50 with a longer case. MagnaFlow's are a straight- through design that is generally quiet while cruising (especially the 18" version) but come very much alive as you get on it. They do not sound anything like a Flowmaster, but have a subdued glasspack sound when revving. It's all a matter of taste, there's no right or wrong, but you'll probably find that Dynomax has the edge when it comes to sound control, performance, and bang for the buck.

Re: Flowmaster 50 series Delta Flow or Dynomax Super Turbo

My '67 with a 350 had Flowmaster 40's and I had the same problem, too loud and too much drone in the interior. I had them replaced with 50 series Delta. Perfect! Nice exterior sound, no drone inside. My wife and I can now carry on a conversation at highway speeds without shouting.

Re: Flowmaster 50 series Delta Flow or Dynomax Super Turbo

Dynomax 17665's on mine. Nice and quiet in car at cruise. Sound awesome when the 505 goes into tire smoke mode Engine made 8 HP less on dyno with these mufflers compared to open headers and 16" extensions.

Re: Flowmaster 50 series Delta Flow or Dynomax Super Turbo

Don't forget about your sponsor's mufflers... Pypes Exhaust. We have Race Pro's which are equivalent to the 50 series and the CFM flow of these are just about the same as a straight pipe... 492.2 vs 500 cfm. They are the only muffler with packing inside to get rid of the drone. I have them on my two cars and I love the sound. It's a real nice Musclecar sounding muffler at idle, them what you get on it, it's loud, but when you back off and cruise, it's a nice mellow tone.

Here's a link of 71 Chevelle with a 3" Race Pro mufflers on it. Granted it's 3" which is a bit louder than the 2.5", but you can get the feel of it.

Here's a drive-by with the same car.

PM me and I can give you a really good deal on these mufflers...
Thanks... Mike
