Quiet!
I have the Colt exhaust on my 2001 Grand Cherokee WJ that comes with 14" body, 9" wide single chamber muffler (a common size EVERYBODY makes). I liked it but over time I got fatigued with it's volume. If I was 21 I'd have probably left it. This Dynomax was a direct replacement for the (or any) 14" muffler. Almost bought the #17747 which is a 20" body of the same muffler and close to the oem size muffler. Glad I didn't because that would have likely been too quiet. This one is already hardly louder if any than stock but it sounds good all the time and at every rpm. Can also hold conversations and listen for other noises in the vehicle (it's a 24 year old vehicle, that's important lol). This is about as civilized of a performance muffler you're going to find.

Muffler
That's exactly what I ordered by part number 2 1/4 in and out. It has a deep rich sound with a 12-in tell pipe turned down. This is on my 1997 Chrysler Sebring 2.5 l motor with resonator left on

Sonido moderado pero fino
Da un sonido moderado y fino. Lo cual hace que el coche suene elegante. Es como un volumen similar al original, pero en tono grave. Haciendo que los coches parezcan qué suenan así de agencia.

good deep sound
instal instead of rear mufflers on Challenger V6, got a good deep tone, not loud, no drone. this is what i wanted. Could be more rumble, but it is fine. More loud- more drone, had experience.
