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%.
