Recommend me some racing mufflers for my Charger

[KohrtRacing]

Looking for recommendations for best flowing / sounding muffler for a 383 B-Body with 2.5” full exhaust? I don’t care for the stock motor open header sound and have to have the ability to tune at home (neighbors ) so full exhaust is going back on my Charger.

I hear good things about Dynomax? Flowmaster too. I threw my Summit exhaust kit back on but figured I’d upgrade the 2-chamber mufflers it comes with. Any good resources to listen/view outside of the manufacture site and YouTube? I’m seeking the classic muscle car sound with some bite when wide open during racing.

Thanks in advance. Mid-13’s with my ‘68 Charger nicknamed “Project 68.”

Dynomax ultra flow or magnaflow.

Dynomax ultra flows are very hard to beat.
Good sound, good horsepower, not too loud.
I have 3"magnaflows on one of my cars. Nice long case, good flow, quiet-ish.
Jones makes several very inexpensive stainless mufflers, available at summit.

Flowmaster all the way, their super 10's have a good sound

Flowmaster should be called Flowless.....
Jim Hand tested a large number of 2.5" mufflers in his Pontiac book. Compared to an open pipe, FM were below 60%. Dynomax Ultra flow was 99% & Dynomax Welded Ultra Flow was 101%.

Go old school...Purple Hornies, Thrush Cherry Bombs, Thrush Rattlers. They all have that classic muscle car sound.

Cherry bomb header muffler. Sounds great... flows great.

I had to change to a chambered muffler from the ultra flows. They were great but I do like the the Hooker ultraflows

I just switched to Hooker Ma-flows and am pretty happy with them... i also added some resonators in my tailpipes to quiet it a bit more (3" out the back) and am pretty happy with it now..

What resonators did you go with? What is the outside diameter?

amazon specials.. they are only 3.5" outside diameter... i wish i had gone 4.5" but i wasn't sure how much space i had... The main reason i got them is my exhaust was crazy raspy (think old mans 78 chevy pickup) which i 100% hate.. it cleared that right up..

To the OP - at your power level, you have a lot of options. If sound is a key criteria, I’m not sure I can help much. The right sound is truly a personal choice/opinion.

On the quieter side, you can run the Dynomax Super Turbo mufflers. I ran the 2 1/4” long body version (17747?) in my car. I Ran 12.8s @ 109 mph in my 4200 lb Charger with them.

Hooker maxflows won a 1000hp muffler shootout on engine masters. Forgot about them.
I had hooker aeros on this car. Sounded good, ran good. They were the cheapest 3.5 in/out I could find at the time. Never ran it uncorked.

Wow thanks for this reference. Great episode, never saw this one. Glad I went 2.5” as my hunch suspected there wasn’t a big difference. They reveal the answer. Spend the money on the good flowing mufflers!

I wish i had gone 2.5".. i went 3" cause i'm a 16 year old at heart and it's just too loud

Best for flow would be a straight through design. Flowmaster Fx are a cheap, flow through unit. https://www.amazon.com/Flowmaster-71419-FlowFX-Muffler-Stainless/dp/B07J2L2KM4?th=1

I guess that makes me twelve. (I went 3.5 systems on two of my cars, lol)

you can get them in many sizes & configurations stainless steel
not very expensive either last I saw
FlowX by Flowmasters
straight thru welded design, not just crimped like others
well sort of, it's a slight bent from end to end, see thru with an offset enter & exit

like $69 at Summit Racing, sounds great too, a lil' throaty but not too loud
especially if you use tail pipes out the rear
no drones either, if using the proper sized pipes
